mechanisms of fungal pathogenesis. Some of his lepidopteran larvae. Recently he has collaborated with recent research (at Boyce Thompson Institute) focused John Vandenberg (USDA ARS) on testing fungi for on the use of molecular probes for differentiating control of the diamondback moth and the cabbage pathotypes within the Entomophaga grylli complex and maggot. species of deuteromycetes. Mike Villani is also based in Geneva, New York. He The Cornell Veterinary Entomology Program is under investigates management and control options for white the direction of Don Rutz with Research Associate grubs, primarily as pests in turf grass systems. He has Wes Watson and Graduate Student Stefan Long. The tested fungi, bacteria and nematodes for grub control primary focus of the group is the control of arthropod and has demonstrated their effects on grub behavior pests of livestock and poultry. Research efforts are within the soil. directed toward the development and use of entomopathogenic fungi Beauveria bassiana and Entomophthora muscae as biological control agents of house flies and stable flies. Other studies focus on the The USDA ARS Collection of Entomopathogenic biology of a recently discovered pathogen of fly Fungal Cultures, curated by Richard Humber, is now parasitoids, Nosema muscidijUracis, and other approaching 5000 accessions of more than 300 fungal Microsporidia. taxa from nearly 900 different invertebrate hosts and all parts of the world. This culture collection is the Elson Shields studies the biological control of alfalfa largest and most diverse of its sort worldwide. snout beetle, Otiorhynchus ligustici with the Associated activities include research on classical and entomopathogenic nematode, Heterorhabditis molecular approaches to the systematics and taxonomy bacteriophora. The northern New York strain of fungal entomopathogens (most recent efforts focus "Oswego is adapted to persist in the soil throughout the on VerticiOiumLecaniiand other hyphomycetes) and by severe winter conditions. After reintroduction into Graduate Student Kathie Hodge on morphological and field plots in 1991, this strain has persisted for> 40 molecular aspects of Hirsute/la. months. To date, excellent control has been achieved in small field plots. Ecologist Alan Sawyer and Support Scientist Mike G~ study the population ecology and epizootiology Also, in the Department of Entomology, graduate of fungal entomopathogens, with the goal of integrating student Sarah Vance, studying under Bobbi fungal biological control agents into insect pest Peckarsky, is completing a Ph.D. thesis on management programs. They are currently focusing mermithids parasitizing mayflies and mosqitoes. on Zoophthora radicans as a pathogen of the potato Graduate student Kirsten Hural, working under Sarah leafhopper. Via, is completing a Ph.D. thesis on variability in pathogenicity and susceptibility in an John Vandenberg studies and develops entomophthoraleanlaphid system. Professors Mike entomopathogenic fungi as biocontrol agents of pest Hoffmann, Paula Davis, Rick Roush, and Ward insects of agricultural crops. Current target fungi and Tingey have also been involved with research projects pests include Beauveria bassiana and PaeciLomyces using pathogens for insect control. fumosoroseus against the Russian wheat aphid and the diamondback moth. Support Scientist Mark Ramos Tony Shelton and Support Scientist Juliet Tang are coordinates field, greenhouse, and laboratory assays based in Geneva, New York, and study the against these pests. Post Doc Frank Cantone studies management, spore-toxin interaction, molecular the biology and genetics of P. fumosoroseus and biology and genetics of Bacillus thuringiensis in the determines the bases of fungal virulence and Graduate diamondback moth. Shelton has also been actively Student Jennifer Altre studies details of the infection involved with Alan Wood (Boyce Thompson Institute) process of these fungi in these pests. in field testing recombinant baculoviruses against.
