Residual efficacy of pyriproxyfen and hydroprene applied to wood, metal and concrete for control of stored-product insects
Pest Management Science 65 (7), 791-797
Abstract: BACKGROUND: Pyriproxyfen and hydroprene are insect growth regulators (IGRs) that have been evaluated to control insect pests of field crops, but there are limited reports of efficacy against stored-product insects. A laboratory study was conducted to determine residual efficacy of pyriproxyfen and hydroprene on wood, metal and concrete surfaces. Pyriproxyfen was applied to the surfaces at 1.15 and 2.3 mg active ingredient [AI] m-2, while hydroprene was applied at the label rate of 19 mg AI m-2. Late-instar larvae of Tribolium confusum Jacqueline DuVal, T. castaneum (Herbst), Oryzaephilus surinamensis L., Lasioderma serricorne (F.) and Plodia interpunctella (Hübner) were exposed with a food source on the treated surfaces. Residual testing was conducted at 1, 28 and 56 days post-treatment.
RESULTS: Hydroprene was least persistent on concrete and generally most persistent on metal. Pyriproxyfen gave greater residual persistence than hydroprene, and there was no consistent difference in efficacy among the three surfaces. Efficacy varied among the five insect species, but generally P. interpunctella was the most tolerant species to both IGRs.
CONCLUSIONS: Pyriproxyfen gave effective residual control of primary stored-product insect species by inhibiting adult emergence of exposed larvae. Results show that pyriproxyfen can be a useful addition for pest management programs in mills, warehouses and food storage facilities.
