Non Technical Summary
Cerambycid beetles are key pests of trees worldwide, and cause further damage to lumber and wooden products. They are among the most common exotic insects associated with wooden packing materials and products intercepted in international quarantine. The primary management tactics for economically important cerambycids is application of insecticides or removal of infested trees. Little is known of their reproductive behavior and semiochemistry. We propose a concerted project to study patterns of use of pheromones by cerambycids. From a basic science viewpoint, these results will provide the raw material for drafting the first rough outline of patterns of pheromone chemistry and use within the Cerambycidae, and will shed further light on their various mate location strategies. These data also will allow testing of several hypotheses that relate to pheromone use. From a practical standpoint, many of the species to be studied are of economic importance, and identification of their pheromones will provide key information required for development of pheromone-based tools for monitoring and control. Furthermore, an outline delineating taxonomic patterns of pheromone chemistry and pheromone use will be enormously valuable for facilitating the identification of pheromones of invasive species as they inevitably arrive in the United States. This in turn will expedite development of methods for their detection, control, and eradication.

Goals / Objectives
1. To test for the use of volatile sex or aggregation pheromones in 20 species of beetles of the family Cerambycidae. 2. For those species that show evidence of attractant pheromones, to identify, synthesize, and confirm activity of the compounds. 3. To locate the glandular source of volatile pheromones for those species shown to produce such pheromones. 4. To use the data generated in Objectives 1-3, and all previous data from the literature to develop the first outline of trends in pheromone use, and trends in pheromone structures, in the Cerambycidae. 5. To use the data generated in Objectives 1-3 to test the following specific hypotheses: H1: For species that use volatile, male-produced sex or aggregation pheromones, male beetles will possess sex-specific prothoracic pheromone glands and the associated cuticular pores. H1 Corollary: Males of species for which there is no evidence of male-produced sex or aggregation pheromones will not possess the prothoracic glands and pores. H2: For species that use volatile, male-produced pheromones, male beetles will exhibit the characteristic calling behavior while producing pheromones. H3: For species that use volatile, female-produced pheromones, female beetles will possess sex-specific pheromone glands associated with the ovipositor.
Project Methods
For our studies, we have available approximately 30 cerambycid species spread over four subfamilies and 23 tribes. Objective 1. To test for the use of volatile sex or aggregation pheromones in each study species. Both sexes of all study species will be tested for pheromones in several ways: 1. If mating occurs on the larval host, beetles will be caged on cut logs in screen cages, whereas species that mate on foliage or inflorescences will be caged on the appropriate portions of the host. We will capture and sex wild beetles arriving on cages. 2. We will bioassay each sex with an olfactometer for a response to odors from males and females, respectively. Study species for which there is evidence of volatile pheromones will be carried on through Objectives 2 and 3. Objective 2. For those species that show evidence of attractant pheromones, to identify, synthesize, and confirm activity of the pheromone components. For all study species, odors released by individuals and groups of single-sex will be trapped to test for sex-specific differences in production of volatiles. Thus, headspace volatiles will be collected on solid phase microextraction fibers for sampling, and on a chemical adsorbent to provide larger samples for fractionation and bioassays. Extracts will be analyzed by gas chromatography (GC) and GC-MS, looking particularly for sex-specific differences in the profiles from males and females. Compounds will be identified by matching GC retention times to those of authentic standards, and by matching mass spectra with standards. As required, microchemical tests to determine the presence or absence of specific functional groups will be used to aid in identifications. If structures cannot be determined from GC-MS and microchemical tests, larger samples will be collected and purified by HPLC and/or preparative GC for NMR analysis. Absolute configurations of chiral compounds will be determined by synthesis of racemic material and one or both enantiomers, and analysis of the native and synthetic materials on a chiral stationary phase GC column. Identified compounds that are not commercially available will be synthesized to provide material for laboratory and field trials. Pheromone components and blends will be tested and optimized in the field. Objective 3. To locate the glandular source of volatile pheromones, for those species shown to produce such pheromones. For those species in which the experiments above confirm that males produce an attractant pheromone, the prothoraces of both sexes will be examined by light and scanning electron microscopy, looking specifically for male-specific pheromone glands and the associated pores opening onto the cuticle. We will determine the underlying structure of pheromone glands by examining cross-sections of the appropriate body parts under light microscopy. Objective 4. To use the data generated in Objectives 1-3 to develop the first outline of trends in pheromone use, and trends in pheromone structures, in the Cerambycidae.

Impacts
Our research has generated interest in the potential for using generic pheromones as probes to assess the species composition of communities of wood borers and also to detect new invasive species. Our methods now are being tested by colleagues in Hawaii, Chile, Canada, Brazil, the United Kingdom, the Czech Republic, China, New Zealand, as well as other areas of the United States. We have greatly refined and improved the design of pheromone traps, with the result that traps are much more efficient and longer lasting. These improvement are essential for developing pheromone technologies to be used for managing cerambycid species that are pests and for monitoring for invasive species. In the process, we also have identified new pheromones for many species with the goal of identifying phylogenetic patterns in the use of pheromones and pheromone structure. That information would greatly expedite the research involved in pheromone identification for new species, particularly new exotic species.

Impacts
The research has lead to improvements in design of traps for capturing cerambycid beetles, particularly in development of more effective pheromone emitters. Our research last year revealed that some species produce pheromones that are more complicated in the chemical composition than previously reported. This finding has important implications for identifying pheromones of new species, and we have modified our approach as a result. We also have conducted a survey of more than 100 species for a morphological character that is associated with pheromones, and this study has revealed than most of the species have the character (and therefore are likely to use long-range pheromones for mate location). We also have discovered that pheromones of many cerambycid species are comprised of one particular compound, either alone or as an important component, and multiple species within beetle communities will respond to this compound. This finding suggests that cerambycid species are cross attracted to pheromone of other species, with important implications for competition for resources.
