The lesser mealworm, Alphitobius diaperinus: Field trials for control in a broiler house with insect growth regulators and pyrethroids

摘要

abstract_textpTwo trials were conducted under field conditions for control of the lesser mealworm, Alphitobius diaperinus (Panzer), in a broiler growout house. Larvae were controlled with treatments applied after litter cleanout and either before the addition of new litter or to the surface of new litter. Three benzoylurea insect growth regulators (IGRs) and two pyrethroids provided 95-100 control of larvae through a 42 d grow-out period. The IGRs hexafluron, triflumuron, and UC84572 were equally as effective in controlling larvae as the two pyrethroids, cyfluthrin and permethrin. The pyrethroids greatly reduced the adult beetle population within 7 d posttreatment and held the population at low levels through the 42 d study; control of adults with the IGRs was not comparable. Numbers of adults were lower in most IGR treatments but in general not significantly different than untreated controls. Adult migration from untreated areas could have influenced these results./p/abstract_text
