| Abstract: | Applications of a commercially produced Beauveria bassiana product, balEnce, were compared with pyrethrin treatments for the control of adult house flies in New York high-rise, caged-layer poultry facilities. An integrated fly management program, which included the release of house fly pupal hymenopteran parasitoids, was used at all facilities. Adult house fly populations were lower in B. bassiana-treated facilities during the spray and post-spray periods, as recorded on spot cards. Concurrently, the numbers of house fly larvae recovered in B. bassiana-treated facilities were less than one-half that of the pyrethrin-treated facilities. House fly pupal parasitism levels were low, but similar under both treatment regimes. The numbers of adult and larval Carcinops pumilio, a predatory beetle, recovered from B. bassiana-treated facilities were 43 and 66% greater than from the pyrethrin-treated facilities, respectively. |
