Below are the names of former PMRU scientists with links to publications and other resources from their research efforts.
Retired - Insect Pathologist with PMRU's Grasshopper and Mormon Cricket Research Program (2000-2018)
Deceased - Research Plant Ecologist with PMRU's Biological Control of Weeds Research Program (2008-2018)
At Sidney ARS, Dr. Jaronski’s research centered on biocontrol of grasshoppers on U.S. rangeland, as well as continuation of older research on management of soil dwelling insect pests of various crops, including sugar beets and corn. His grasshopper work evaluated new technologies and new insect pathogenic fungi for the microbial control of grasshoppers, in close collaboration with USDA APHIS CPHST. This research included identification of baits, and chemical synergists, as well as new, better fungi and other microorganisms, and taking such technologies from the lab bench to the field. In the process, Dr. Jaronski created small scale solid substrate mass production systems based on his industrial experience which not only allowed Kg amounts of fungus spores for testing, but also provided technical advice about such technology worldwide. As a side project he studied the population genetics of Beauveria bassiana derived from grasshoppers using molecular techniques and comparing the molecular data with other phenotypical charactersitics of the more than 400 Beauveria isolates. His soil insect-targeted research was directed toward developing a practical mycoinsecticide, based on discovery of Metarhizium microsclerotia, that can be transferred to industry for commercialization for use against soil pest insects (sugarbeet root maggot, cabbage maggot, corn rootworm). The sugarbeet research is within the larger context of a biologically based management system for both pests and pathogens, using microorganisms, cultural practices, resistant/tolerant hybrids, and induced systemic response.
Dr. Jaronski had joined NPARL in March 2000 as an insect pathologist after a 17-year career in industry. After a Ph.D. program and two postdoctoral appointments concerning microbial control of mosquitoes, he did an abrupt left turn and (a) left the academic community for industry, (b) changed from medical entomology to agricultural pests. From 1983 to 1992, he worked at Abbott Laboratories as an insect pathologist, during which time his research involved commercial development of Beauveria bassiana and Bacillus thuringiensis for use against a wide variety of insects. In 1992 he switched to Mycotech Corp., Butte MT, a small, venture-capital biotech group commercializing Beauveria-based mycoinsecticides. There, Dr. Jaronski spent 8 years involved in all aspects of commercial development of the fungus - from the early basic research through field trials to generation of registration data, from basic mycology to formulation chemistry, from science to marketing. His last position prior to joining ARS was Manager of Biopesticide Research and Development for Mycotech.

Dr. Espeland’s research with NPARL’s Pest Management Unit focused on establishment, genetic identity and evolutionary potential of restored native populations in the face of biological invasions. This research includes the role of competition on restoration success, the role of genetic identity and maternal effects on the establishment of restoration materials. Additional research was established to track whole-ecosystem recovery after weed removal and restoration; this includes bird, insect and plant populations as well as soil conditions.
