Efficacy of tetrachlorvinphos insecticide dust against darkling beetles in commercial broiler chicken barns

Abstract

Residual application of tetrachlorvinphos dust (Debantic 50WP) was evaluated against darkling beetles in commercial broiler chicken barns. The dust formulation was applied using an electrostatic duster after clean out of old litter at the start of a new broiler cycle. Tetrachlorvinphos dust provided adequate control of beetle larvae and adults up to 5 wk. One time of application is adequate for one commercial broiler chicken production cycle only.
