Insecticidal effect of synthetic products and plant extracts on Alphitobius diaperinus. Popularly known as lesser mealworm or litter beetle, Alphitobius diaperinus (Panzer, 1797) has been causing damage to both the production and the health of poultry in confinement, becoming a major pest in the poultry industry. This study evaluated the insecticidal potential of plant extracts and synthetic products on adults of A. diaperinus. The experiments were conducted in laboratory conditions, under controlled temperature and relative humidity. The treatments consisted of extracts of Cinnamomum verum L., Allamanda cathartica L., Ateleia glazioveana Baill, Cymbopogon sp., Chrysantemum sp., a commercial product based on Neem (Azadirachta indica A. Juss.), insecticides lambda-cyhalothrin, dichlorvos and the control (distilled water). Survival evaluation was performed every 24 hours for 72 hours. The analysis of variance (ANOVA) was applied to compare the treatments. The most efficient treatments were dichlorvos and Neem, with 100% efficiency. There was no insecticidal activity against A. diaperinus for the commercially recommended insecticide (lambda-cyhalothrin) and for none of the plant extracts tested in the study. Finally, it is pointed out the advances obtained, as well as perspectives for effective use of products in the population control of the lesser mealworm.
