The lesser mealworm, Alphitobius diaperinus Panzer (Coleoptera: Tenebrionidae), is the most important pest in poultry production systems worldwide. Adults and larvae serve as alternative low-quality food for chickens and as a vehicle for animal pathogens resulting in signiﬁcant economic losses for farmers. Control of this pest is usually performed through insecticide application during the interval between chicken ﬂocks. However, due to the cryptic behaviour of this pest, chemical control is usually not eﬀective. With the aim of developing a sustainable approach to control A. diaperinus, we evaluated integration of the A. diaperinus aggregation pheromone with a highly virulent strain (Unioeste 04) of the fungus Beauveria bassiana (Bals.) Vuill. (Ascomycota: Cordycipitaceae) using an attract-and-infect device. Signiﬁcant levels of A. diaperinus mortality and lower numbers of oﬀspring (larvae) were observed in laboratory experiments using Unioeste 04. Horizontal transmission of the Unioeste 04 strain through contaminated living A. diaperinus and cadavers was also observed. In ﬁeld experiments in commercial poultry houses, a signiﬁcant level of A. diaperinus mortality was observed in Unioeste 04-treated arenas. The results show that the A. diaperinus aggregation pheromone can be used as an attractant in a device impregnated with infective fungal propagules, increasing adult infection and enhancing disease spread. In addition, the use of the microbial control agent inside the device allows the fungus to remain eﬀective for longer periods in the adverse conditions of the poultry house environment.
