What was accomplished under these goals?
Invasive non-nativeorganisms have a costly impact upon forest health and the economy.Financial loss from invasive species in forests can reach billions of dollars annually, but this adverse financial effect can be lessened by early detection and prompt management. The ultimate success of management will depend upon studies designed to develop effective monitoring methods and to elucidate the biology ofinvasive pests. Thorough research on invasive insects innortheastern forests has been limited to a few high-profile insects, such as the Asian longhorned beetle and the emerald ash borer. The investigations conducted during this project focused upon insect groups and speciesthat have not been studied thoroughly in forests of the northeastern United States.The research should contribute to the design of effective detection and monitoring methods for several pestiferous species, to the understanding of the biology and impact of invasive species, and to the development of a comprehensive database for longhorned beetles. Biological data derived from studies should assist stakeholders in sampling for invasive species. New trapping methodology and biological information should aid in the design of management programs for several alien insects that have invaded northeastern forests. Collectively, the results of the project should contribute to decreasing the negative impact of invasive insects upon forest health and products and improve sustainable forestry. During this project, chemical lures wereshown to be highly attractive to adults of the European spruce needleminer, the Japanese cedar longhorned beetle, and the spotted wing drosophila. Traps with lures can be used immediately to detect these pests earlyand thus to allowprompt intervention to reduce damage. In field experiments, feeding by the lily leaf beetle significantly reduced the weight of wild lilies, thus, demonstrating for the first time that this invasive species is impacting native lilies and potentially altering biodiversity. The comprehensive database developed with data collected during this study and from museum specimens provides a valuable tool for determining the seasonal activity,distribution, and hosts of destructive wood-boring longhorned beetles.Such information will be essential to the design of control programs. Objective 1: Develop detection and monitoring methods for non-native invasive insects. In field trials, male moths of the European spruce needleminer (Batrachedra pinicollela) were attracted to wing traps baited with a sex attractant that contained 100 milligrams of Z-5-decen-1-ol and 100 milligrams of Z-5-decen-1-yl acetate in plantations of Norway spruce (Picea abies), the favorite host. Minor changes in amounts of the two chemicals in the pheromone lure did not significantly alter the total catch. Males flew for 5-6 weeks between lateMay and mid-July; the start of the flight in each plantation varied by 1 week over a 3-year period and was 1 week earlier in southern than northern Connecticut. Based upon captures in wing traps, the invasive moth occurs throughout New England and in New Jersey, New York, and Pennsylvania. In 2015, panel traps baited with (R)-3-hydroxyhexan-2-one, a sex pheromone, and with1-(1H-pyrrol-2-yl)-1,2-propanedione, a natural product of unknown function, captured more adults of the Japanese cedar longhorned beetle (Callidiellum rufipenne) than did traps baited with just one of the compounds or with nothing. The European barberry fly (Rhagoletis meigenii) was successfully captured with baited yellow sticky traps that are sold commercially for the highly destructive apple maggot fly (Rhagoletis pomonella). When these traps were deployed in common barberry (Berberis vulgaris) and Japanese barberry (B. thunbergii) over 3 years, they captured mainly females over 5 weeks between mid-June and late July, with the start and the end of the adult flight varying by 1 week. Small translucent cups baited with apple cider vinegar successfully trapped the invasive spotted wing drosophila (Drosophila suzukii) throughout Connecticut. Efforts to recover the invasive katydid (Meconema thalassinum) in the nests of wasps (Isodontia spp.) in artificial structuresdeployed in forests were unsuccessful. Objective 2: Provide new information on the biology and impact of the lily leaf beetle and the barberry fly.In field cages, individual plants of the native Canada lily (Lilium canadense) were supplied with 0, 5, or 10 eggs (2013) and with 0, 5, or 10 neonate larvae (2014) of the lily leaf beetle (Lilioceris lilii) in May to measure the impact of feeding upon plant growth. When the dry weight of lilies in each group was measured in late July or early August and analyzed with an analysis of variance and the Tukey test, the dry weight of whole plants was significantly higher in the controls (0 eggs or larvae) than in the two groups with larval feeding. In 2013, larvae that fed after hatching from 10 eggs had a mean dry weight of only 16.1% of that of the controls. In 2014, Canada lilies with 10 larvae had a mean weight of 24% of that of the controls. Based upon the comparison of mean dry weight, the impact of beetle feeding was slightly less in 2014 than it was in 2013. The reduced impact in 2014, however, may have been due to the plants being larger at the time of infestation. Over 3 years, the berries of the two exotic barberry species were infested with the European barberry fly. Surprisingly, the larvae that exited the fruit were not parasitized. To exclude the possibility that parasitism happened after the larvae had dropped to the ground to pupate, pupae from rearing enclosures filled with sand were removed, placed inthe soilscreened cages (with the top removed) in September, and retrieved in late Mayto allow parasitoids to emerge.Again, no parasitoids appeared in the rearing containers in the laboratory. Despite the fly apparently being parasitoid-free, the density of flies in berry samples and captured on sticky panels did not increase enough over the course of the study to suggest that the fly might be a suitable biocontrol agent. Based upon flies reared from samples and captured on sticky panels, the density ofthe barberry flyis higher in common barberry, the original host plant, than in Japanese barberry. Objective 3: Develop a database on the longhorned beetles of Connecticut. Data from adults of longhorned beetles (Cerambycidae)captured in traps or on flowers, reared from infested wood, attracted to lights, captured in flight interception or on sticky traps, and deposited in major museums were compiled in an Excel database.Biological data from over 20,000 specimens were entered into the database thatincludes information on distribution, activity periods, hosts, and methods of sampling. This database will be used to develop an annotated checklist of the longhorned beetles of Connecticut, as explained in my next research proposal (McIntire Stennis 397). During the 4-year project,91 species, or about 47% of the estimated cerambycidfauna of Connecticut, were reared from the wood of dead or stressed live trees.In all, 344 host associations wereconfirmed, with anaverage of 3.7 hosts/ reared species. The red-headed ash borer (Neoclytus acuminatus acuminatus) used the most hosts, a total of 34.At a major trapping site in North Branford, Connecticut, 51 species of longhorned beetles were captured in traps baited with sex pheromones, host volatiles, or both. The number of captured specimens of 24 species was sufficient to determine their seasonal flight pattern. Panel traps baited with ketones were most proficient in capturing species in the subfamilies Cerambycinae and Lamiinae.Panel and other traps, baited with appropriate attractants, may soon widely be used to detect foreign species that are potential pests of northeastern forests.

Invasive exotic organisms have a negativeeffect upon forest health and the economy. Invasives in forests can cost billions of dollars annually, but this adverse financial impact can be lessened by early detection and prompt management of these pests. The ultimate success of management will depend upon studies designed to develop effective monitoring methods and to elucidate the biology of invasive pests. For the most part, extensive research on invasive forest insects has been limited to a few high profile wood-borers, such as the Asian longhorned beetle (Anoplophora glabripennis) and the emerald ash borer (Agrilus planipennis). The investigations outlined in this project focus upon insect groups and individual species that have not been studied thoroughly in forests in the northeastern United States. The research should contribute to the design of effective detection and monitoring methods for several species, to the understanding of the biology and the impact of two species, and to the development of a comprehensive database on a large group of native and non-native wood-boring beetles (Cerambycidae). New biological data derived from the proposed investigations should assist stakeholders in sampling for invasive species and in recognizing their potential damage. New trapping methodology and biological information should aid in the design of managment programs for several alien insects that have invaded northeastern forests. Collectively, the results of the research should contribute to reducing the negative impact of invasive insects upon forest health, forest products, and possibly biodiversity. Objective 1:Develop detection and monitoring methods for invasive species.For the third consecutive year, adult males of the European spruce needleminer (Batrachedra pinicolella) were attracted to wing traps baited with a sex attractant lure that contained 100 milligrams of Z-5-decen-1-ol and 100 milligrams of Z-5-decen-1-yl acetate in a plantation of Norway spruce (Picea abies). In southern Connecticut, the adult flight of males spanned about 5 weeks in 2014 and started about 1 weeklater in 2014 than 2013.Over three years of trapping, the annual start of themale flight variedby 2 weeks. Based upon captures in pheromone traps, this invasivemoth occurs throughout New England and in New Jersey, New York, and Pennsylvania. The barberry fly (Rhagoletis meigenii), which infests thefruits of invasive barberries (Berberis species), was capturedon yellow sticky traps in North Branford, Connecticut,over 5 weeks between late June and late July. As with the previous insect, the start of the adult flight in 2014was 1 week later than it was in 2013, and 2 weeks later than it was in 2012. To ensure the detectionthe first adults each year, the stickytraps should be deployed no later than the first week of June. The trapping methods used in these studies can be used immediately to detect the European spruce needleminer and thebarberry fly and to monitor their seasonal flight periods throughout the northeastern United States. Objective 2: Provide new information on the biology and impact of the lily leaf beetle and the barberry fly. In a field experiment conducted in 2014, individual caged plants of the native Canada lily (Lilium canadense) were supplied with 0 (control), 5, or 10 first-instar larvae of the the lily leaf beetle (Lilioceris lilii) in May to determine the impact of feeding upon plant growth until late July. When the dry weights of plants in each treatment group werecompared with an analysis of variance and Tukey's test, the mean dry weight of whole plants was significantly higher in the controls (no larvae on plants) than in the two groups initiallyinfested with young larvae. The trend was similarwhen only the bulb weight was considered. Canada lilies initially infested with 10 larvae had a mean dry weight of 24% of that of the controls, and the ones with 5 larvae had a dry weight of 55.3% of that of the controls.Based upon final dry weight, the impact of beetle feeding was slightly less in 2014 than it was in 2013.This reduction may have been due to the plants being larger at the time of infestation in 2014 than 2013. Also, in 2014 an unidentified small mammal destroyed 50% of the caged lilies, greatly reducing the the number of plants available for comparisonin each experimental group. Thus, based on the field experiments conducted in 2013 and 2014, feeding by lily leaf beetles detrimentallyaffected the growth of wild lilies, and, in particular, theweight of their overwintering bulbs. For the second year, no parasitoids of the barberry fly emerged from samples of infested wild barberries collected throughout Connecticut.Next year pupae of barberry flies placed in the soil beneath plants will be evaluated for rate of parasitism. Objective 3: Develop a database on the longhorned beetles of Connecticut. New data from adults of longhorned beetles (Cerambycidae) collected in traps or on flowers, reared from wood infested by larvae, or extracted from labels of museum specimens were entered into an Excel database, which now has over 11,760 entries. To date, rearing from dead wood has produced86 species of cerambycids and over 300 host associations. In North Branford, cross-vane panel traps baited with adult pheromones and host volatiles captured 51 species of longhorns, or about 26% of the 200 species currently known from Connecticut. The number of captured specimens of 24 species was high enough to allow their seasonal flight pattern to be determined accurately. Therefore, baited panel traps were excellent for ascertaining the flight period of adults of many species, but particularly those in the cerambycid subfamilies Cerambycinae and Lamiinae.These traps, when provided with appropriate attractants, may soon be used widely to detect new cerambycids that are potentially destructive to wood products.

Non-native invasiveorganisms have a negative impact upon forest health and the economy.Financial loss to invasives in forests can reach billions of dollars annually, but this adverse financial effect can be reducedby early detection and prompt management of these pests.The potential success of management relies heavily upon research to develop effective methods ofmonitoring and toelucidate the biology of pests. Unfortunately, thorough research on invasive insects in northeastern forests has been limited largely to a few wood-boring species, such as the Asian longhorned beetle (Anoplophora glabripennis) and the emerald ash borer (Agrilus planipennis). The research proposed in this project focuses upon insect species and groupsthat have not been studied in-depth in northeastern forests. The investigations should contribute to the development of effective detection and monitoringmethods forseveral species, to the elucidation of the biology andthe impact of two species, and to the formationof a database on the biology of a large group of destructive wood-boring beetles. New biological information derived from the proposed researchshould aid stakeholders in finding invasive species and in recognizing their potential harm. New trapping methodology and biological data will assist in developing management programs for several exotic insects that have invaded northeastern forests.Overall, the findings should contribute to decreasing the detrimentalimpact of invasiveinsects upon forest health and valuable forest products. Objective 1:Develop detection and monitoring methods for invasive insects. In a second year of field trials in plantations of Norway spruce (Picea abies), adult males of the European spruce needleminer (Batrachedra pinicolella), whichcauses cosmetic damage to spruce foliage,was highly attracted to wing traps with a lurebaited with a sex attractant of 100 micrograms each of Z-5-decen-1-ol and Z-5-dececen-1-yl acetate.The male flight period extended from early June to mid-July in 2013; the onset of flight was about 1 week later in 2013 than 2012.The barberry fly (Rhagoletis meigenii), which infestsfruits of non-native barberries (Berberis spp.), was captured on yellow sticky traps between late June and mid-July; the start of the adult flight also was about 1 week later in 2013 than 2012.Efforts to recover the invasive katydid (Meconema thalassinum) in the nests of wasps (Isodontia spp.) invarioustube traps were unsuccessful in 2012.The pheromone traps for the spruce needleminer and the yellow traps for the barberry fly are effective devices that can beused immediately for determining the distribution and seasonal flight patternof these two insects. Objective 2:Provide new information on the biology and impact of the lily leaf beetle and the barberry fly.In a large-scale field experiment, individual caged plants of the native Canada lily (Lilium canadense) were supplied with 10, 5, or0 eggs of the lily leaf beetle (Lilioceris lilii) in May to measure the impact of larval feeding upon plant growth. When the dry weight of the lilies was measured in August and analyzed with an analysis of variance and the Tukey test, the weight of the whole plants was significantly higher in the controls (0 eggs) than in the two groups with larval feeding. In fact, the lilies initially infested with 10 eggs had a dry weight of only 16.1% of that of the controls, and the ones with 5 eggs had a dry weight of only 29.9% of that of the controls. The larvae that fed after hatching from 10 eggs completely devoured the foliage of 47% of the total lilies in their experimental group; no lilies in the 10-egg group developed flowers. Thus, larval feeding by the lily leaf beetle had a severe impact upon wild Canada lilies in cages, suggesting that even moderate infestations in wild lilies may have a detrimental consequences. The barberry fly emerged from 85% of 20 berry samples collected throughout Connecticut, indicating that it is widespread.Surprisingly, no parasitoids emerged from the samples, which contained larvae at the time of collection.Host specific larval parasitoids may not have been introduced into the United States when the fly was. Potential parasitism oflarvaeand pupae in the soil needs to be examined before this fly can be deemed parasite-free. Objective 3:Develop a database on the longhorned beetles of Connecticut. New data from adults of longhorned beetles (Cerambycidae) collected in traps or on flowers, reared from wood infested by larvae,or examined inmuseum collections were entered into an Excel database, which now has 8,700 entries.To date, rearing has yielded a total of 85 species of cerambycids (47% of the known state fauna) and 286 host associations. In North Branford, black panel traps baited with sex pheromones and host volatiles captured at least 43 species of longhorns or about 24% of the cerambycid species currently known from Connecticut. The abundance of 20 species captured in traps was sufficiently high to discern the seasonal flight pattern of adults. Thus, baited panel trapswere excellent for determining the seasonal flight pattern of many species, particularly thosein the subfamilies Cerambycinae and Lamiinae.These traps probably can be used to survey for new, potentially destructive,invasive wood-borersthat are in one ofthe genera or subfamilies known to be attracted togeneric pheromones and host volatiles.

OUTPUTS: Non-native organisms negatively impact the biodiversity and the economy in North America. In forests in Connecticut and other northeastern states, new invasive insects are discovered annually. Early detection of these invasive species is an important factor in decreasing the cost of eradication or management. Despite concern about many invasive insects in the Northeast, research on improved methods of detection and on biology mainly is confined to a few highly destructive species, such as the Asian longhorned beetle, the emerald ash borer, the brown marmorated stink bug, and the spotted wing drosophila. In 2012, traps were deployed in or near forests to determine the seasonal activity of adults of the barberry fly (Rhagoletis meigenii), a potential biocontrol agent for invasive barberries (Berberis spp.), and of the European spruce needleminer (Batrachedra pinicollela), a potential spruce pest. Initially, the trapping data will pinpoint when experiments on these adults can be performed, and, in the case of the European spruce needleminer, when it might be controlled. Data on the infestation of wild stands of true lilies (Lilium spp.) will be valuable in determining the threat to native lilies posed by the lily leaf beetle (Lilioceris lilii), which increasingly is being detected in wild lily populations in northeastern North America. Experiments were designed to develop a method of detecting an invasive katydid (Meconema thalassinum) in forests by using sphecid wasps (Isodontia spp.) that sometimes provision their nests with adult katydids captured on forest trees. The development of effective trapping methods for the barberry fly, the European spruce needleminer, and the katydid will be valuable for mapping their distribution in North America. The larval and adult hosts of longhorned beetles, or Cerambycidae, also were investigated by rearing and trapping to ascertain what woody plants are at highest risk of attack by these wood-borers. Data on hosts, distribution, and trapping of cerambycid beetles were entered into a database that will be used to develop a checklist of the Cerambycidae of Connecticut and to advise stakeholders who might have economic loss from the included species. Experimental results from this project were reported orally or with poster displays at meetings and open houses attended by arborists, fruit-growers, forest managers, maple syrup producers, extension agents, survey specialists, home gardeners, and professional entomologists. PARTICIPANTS: The principal investigator, Chris Maier (Connecticut Agricultural Experiment Station), designed the research and supervised field and laboratory work. During 2012, Morgan Lowry and Tracy Zarrillo assisted with collecting samples in the field, rearing insects, databasing distributional and host records, and preparing figures for publication. Foresters with the Connecticut Department of Energy and Environmental Protection, the Metropolitan District, the South Central Connecticut Regional Water Authority, and Great Mountain Forest, Inc., assisted by finding suitable sites for research. TARGET AUDIENCES: The main target audiences are: arborists, state and private foresters, staff of the Forest Service and the Animal and Plant Health Inspection Service of the United States Department of Agriculture, conservationists, and others interested in invasive species. New information on invasive species in or near forests was disseminated to arborists at the annual meeting of the Connecticut Tree Protective Association, to state and private foresters during a forest health workshop at the Connecticut Agricultural Experiment Station, to fruit-growers at annual and twilight meetings of the Connecticut Pomological Society, to state citizens at the annual field day of the Connecticut Agricultural Experiment Station, and to professional entomologists at the USDA Forum on Invasive Species and at the annual meeting of the Entomological Society of America. PROJECT MODIFICATIONS: Not relevant to this project.
Impacts
The threat of costly injury from invasive insects underscores the need for improved survey methodology and for increased understanding of pest biology. New information that adults of the European spruce needleminer are attracted to wing traps baited with 100 micrograms of Z-5-decen-1-ol and 100 micrograms of Z-5-decen-1-yl acetate between late May and mid-July can be used immediately to monitor adult flight. Experiments in Norway spruce plantations in state forests have shown that both pheromone components are necessary to attract a large number of adult moths, but that the correct ratio and amount of the two chemicals in lures needs to be investigated further. The barberry fly, which infests the fruit of invasive barberries in forest understories, was trapped on yellow sticky panels between mid-June and mid-July. These data will be critical for designing experiments to evaluate the impact of the fly on barberries. Furthermore, the effect of insect parasitoids upon barberry flies is in the inital stages of being evaluated in the laboratory. In 2012, the lily leaf beetle was found in 80% of 10 stands of Canada lily (L. canadense)and in 75% of 4 stands of Turk's-cap lily (Lilium superbum) in Connecticut. These baseline data, along with future experiments in which beetles will be caged with lilies, will show how this invasive beetle affects native lily populations over time. New distributional data from longhorned beetles collected in pheromone-baited traps, new host associations obtained by rearing beetles from dead wood, and new behavioral observations on adults were entered into an Excel database (now with 8500 entries). This database will facilitate the identification of species that develop in woody plants and will assist in predicting the host range of pestiferous species. This new biological information, which includes over 270 host associations of beetles, should contribute to designing effective management programs for pestiferous longhorned beetles. Findings from my diversified studies in coniferous and broad-leaved forests should foster improved forest health in the Northeast.
