The lesser mealworm is one the most important problem to avian production system, being a potential vector of avian and other animal pathogens. The objective of this study was to evaluate the neem cake (Azadirachta indica) A. Juss (Meliaceae) as an alternative to control the Alphitobius diaperinus Panzer (Coleoptera: Tenebrionidae). The neem cake was directly applied to substrates at 100g m^-2 and were evaluated the lethal and sublethal effects to A. diaperinus adults, as mortality, oviposition, repellent effect and feeding. There was no effect on adult mortality, but were observed reduction of the oviposition (23%), repellent effect, and reduction of insect feeding (21%).
