Progress 09/01/00 to 08/31/05
Outputs Mike Rose passed away and this grant was taken over by the Co-PI from another university. I believe he turned in a hard copy of the termination report and summary to the granting agency due to the fact he was from another university.

Progress 09/01/00 to 08/31/04
Outputs Dr. Michael Rose is is deceased. The remaining funds were reliniqued to Kansas State University, Dr. Gregory Zolnerowich. The project will be finalized there.
Impacts The taxonomy of exotic Eretmocerus species attacking Bemisia will enable evaluation of estblishment, distribution and species compositions of exotic speceis, and aid in pest management decisions. Taxonomy of native Eretmocerus species will elucidate species complexes on a broader whitefly host fauna in regions where exotic Eretmocerus are known to exist. This will allow for examination of possible non-target host utilization by exotic species, and possible competiton between native and exotic Eretmocerus for various host resources.

Submitted to Pan Pacific Entomologist. A new native species of Eretmocerus that attacks the American whitefly Aleuropleurocelus nr. oblanceolatus on the New World plant Lantana in the San Diego area of southern California near, but somewhat isolated by a mountain range from, Imperial Valley locations where exotic Eretmocerus were released against and recovered on Bemisia, has been characterized and described, and
illustrations completed. A new native species of Eretmocerus that attacks the cosmopolitan whitefly Trialeurodes abutiloneus (Haldeman) that is sympatric in field crops with Bemisia in the California San Joaquin Valley where exotic Eretmocerus have been released against and recovered on Bemisia, is being characterized and drawings are completed. A new native species of Eretmocerus that attacks the American whitefly Tetraleurodes mori (Quaintance) on Morus, which also harbors Bemisia in the California San Joaquin Valley, is being characterized and drawings are completed. 9. A new species of Eretmocerus that attacks the American whitefly Tetraleurodes perseae, a California invader of avocado, has been characterized and figured. Under review with Vedalia: the International Jour. of Biological Control. Three new American Eretmocerus species reared from Aleurotrachelus, Bemisia and Trialeurodes living on cassava in northern South America are being characterized. These American species are

Sorting of [these] specimens to series believed to represent species. Examination of [these] series of specimens with dissecting and compound microscopes. Digital measurements and analysis of same under the compound microscope. Results for 2001-2002. Eleven Eretmocerus species reared from Aleurothrixus floccosus (Maskell), an American whitefly species from southern South America to the southern U.S., described in Vedalia: The International Jour. Biological Control, in 2001. Three Eretmocerus populations imported from Ethiopia, Hong Kong and Sudan released against Bemisia in the U.S.were examined.

Progress 01/01/01 to 12/31/01
Outputs Numerous populations of parasitic Hymenoptera in the genus Eretmocerus (Aphelinidae) were introduced from foreign countries and released in the United States as natural enemies of the pest whitefly, Bemisia (tabaci group) during the recent national action program run by the USDA. Eight species - four exotic and four native - that attack Bemisia in the United States have been characterized and described by Rose and Zolnerowich. Current field population compositions of Eretmocerus species living in Bemisia, and other non target whitefly species, remains unknown. This research seeks to elucidate the composition of Eretmocerus species living in Bemisia and other whitefly species in areas where exotic Eretmocerus species have been released. State and federal scientists that were active in the release of exotic Eretmocerus agreed to provide samples of Eretmocerus reared from Bemisia and other whitefly (e.g., Aleurothrixus, Dialeurodes, Paralyrodes, Tetraleurodes,
Trialeurodes, etc.) within the exotic species release vicinities on both agricultural and non-agricultural plants to enable this immediate goal. The longer-term goal is to gain background that will allow for assessment of possible non-target whitefly host utilization by exotic species. To this end, the following have been accomplished following microslide curation and examination of series of specimens: Two additional exotic Eretmocerus populations from Ethiopia and Hong Kong that have been released against Bemisia in the U.S. are now being characterized; eleven Eretmocerus species reared from Aleurothrixus floccosus (Maskell), an American whitefly species that occurs from Argentina to the southern U.S., have recently been characterized and described (see Publications); a recently discovered Eretmocerus attacking a newly invading Asian whitefly, Aleuroclava jasmini (Takahashi), in Florida has been characterized and this publication will soon be submitted (see publications); two new
species of Eretmocerus that attack Tetraleurodes acaciae (Quaintance) in areas of southern California where exotic Eretmocerus have been released against and recovered from Bemisia are being characterized and described (see publications); three new species of Eretmocerus reared from non-target whitefly on non-agricultural desert vegetation in and around the California Imperial Valley where exotic Eretmocerus releases have been intense are being characterized; a new species of Eretmocerus reared from both Trialeurodes abutiloneus (Haldeman) and Bemisia in areas of Florida and Georgia where exotic Eretmocerus species have been released is being characterized; and six new species reared from Bemisia, Trialeurodes and Aleurotrachelus in the Americas are being characterized
Impacts A better understanding of the Eretmocerus species complexes attacking whitefly in the Americas. The establishment of exotic Eretmocerus species on Bemisia in the U.S. Possible non-target host utilization by established exotic Eretmocerus species.

Progress 01/01/00 to 12/31/00
Outputs Specimens from cooperators in California and Texas are being curated and examined. Slide-mounted specimens are being sorted into exotic and native groups. Series of specimens are being sorted into series that are thought to represent species. Additional specimens are expected from all cooperators as the warm season allows for field recovery sampling.Exotic populations from Bemisia originating in Hong Kong and Ethiopia are being characterized.Original specimens from Ethiopia are to be provided by USDA cooperators. Specimens from a multiple year survey of 4 species of whitefly in Columbia taken from a single host plant will now be included in this study. Examinations show that 4-5 undescribed species of Eretmocerus are involved. Understanding this species diversity will aid our understanding of species diversity and characterizations in the US.
Impacts Evaluations of the national Bemisia program will be enhanced as species are discriminated.
