2005 Annual Report 4d.Progress report. This report serves to document research conducted under a Specific Cooperative Agreement between ARS and the University of Idaho, Parma Research and Extension Center. Additional details of research can be found in the report for the parent project 5428-21000-010-00D, Pollinating Insect-Biology, Management, Systematics Research. Project Objectives: 1. Conduct laboratory, greenhouse, and field experiments examining the non-lethal and sub- lethal effects of pest management practices on pollinator biology and behavior, and subsequently on crop pollination. 2. Conduct laboratory, field, and greenhouse experiments to examine the lethal effects of pest management practices on pollinators and subsequently on crop pollination. Project report: This work provides the alfalfa seed industry with information concerning the safety to alfalfa leafcutting bees and important lygus bug predators of currently registered and potentially useful pesticides. We are trying to recruit a graduate student to conduct work outlined in objective 1. We are currently establishing the residual toxicity (RT25) of field-weathered foliage treated with acetomiprid, carzol, clothianidin, and novaluron, to alfalfa leafcutting bee and to several natural enemies of lygus bugs occurring in alfalfa seed fields. Data to date indicates that all of these compounds applied alone are safe to leafcutting bees, within 24 hours after application. Clothianidin remained very toxic to minute pirate bugs for more than 4 days after application. Carzol remained toxic to damsel bugs, bigeyed bugs and minute pirate bugs 3 days after application or longer. Assail remained toxic to minute pirate bugs more than 4 days after application, but was relatively safe to bigeyed bugs and nabids. 7.List your most important publications in the popular press and presentations to organizations and articles written about your work.
