Evaluation of new traps and attractants to improve pheromone/kairomone-based monitoring systems will involve the selection and formulation of different kairomones and kairomone combinations, and different pheromone release rates by the cooperator, and testing by ARS of stored-product insect response to these attractants using observational behavioral analysis and wind tunnel, small box, and large room bioassays. For the evaluation of mating disruption, warehouse pheromone dispensers will be developed by the cooperator, and the impact of high levels of pheromone release on warehouse beetle mating success, population growth, and colonization will be evaluated by ARS. In addition, data from field trials of mating disruption programs for Indianmeal moth will be evaluated to determine overall efficacy and identify factors that impact efficacy. The more specific research approaches used by ARS are listed below. a. Evaluation of new traps and attractants to improve pheromone/kairomone-based monitoring systems. i. Evaluation of new kairomones against the standard kairomone using wind tunnel bioassay. ii. Determine how new kairomone for red flour beetle influences the response of warehouse beetle, cigarette beetle, drugstore beetle, sawtoothed grain beetle, granary weevil, and confused flour beetle. iii. Determine the impact of pheromone release rate on red flour beetle response to kairomone using new Dome trap design. iv. Test prototype of new Dome trap design and attractants in windtunnel and large chamber (20 by 16 ft) tests. Use paired tests of new versus standard trap/attractants using red flour beetle and choice tests of new trap design and other commercially available traps. v. Evaluate behavioral interactions with new adhesives used in sticky traps. b. Initiate development of a mating disruption system for warehouse beetle. i. Conduct shed studies determining the feasibility of mating disruption for warehouse beetle: impact on mating, oviposition and population growth. 1. Release immature stages of warehouse beetle into sheds in patches of diet and evaluate the rate of population growth with and without mating disruption (up to 6 month tests so can evaluate multiple generations). Also include initially uninfested patches to determine impact of treatment on patch colonization. 2. Evaluate the behavior of males and females under mating disruption conditions and measure mating success. ii. Evaluation of mating disruption datasets from commercial food facilities, and conduct mating disruption trials in several commercial food facilities. c. Provide regular updates and annual reports on progress.
