Research Project: Evaluation of Novel Entomopathogenic Fungi for Grasshopper Management

Location: Pest Management Research Unit

2011 Annual Report


1a.Objectives (from AD-416)
Identify new, better entomopathogenic fungi (Metarhizium, Beauveria spp.) that are pathogenic to grasshoppers and Mormon crickets.


1b.Approach (from AD-416)
Utah State has isolated well over 400 isolates of the two fungi, with funding from USDA APHIS, in the search of a good mycoinsecticide for Mormon crickets. These isolates will serve as the basis for ARS identifying a candidate(s) for grasshopper management in parallel to Utah State’s objectives. Utah State will provide as many as 400 isolates, based on selection by both ARS and Utah State. ARS will evaluate these isolates using multiple criteria, including pathogenicity towards grasshoppers, mass production potential, thermotolerance, and selective nontarget insect studies.


3.Progress Report

Northern Plains Agricultural Research Laboratory, Sidney, MT, accessed 150 Metarhizium isolates chosen from Utah State collection, for evaluation as potential mycoinsecticide for grasshopper and Mormon cricket control. Subcultures were made from received material, place in long term storage; preliminary evaluations of spore production were completed and bioassays partially completed. ADODR monitoring was via bi-monthly telephone calls or emails to update partner on results.
