Ocorrência de Metarhizium anisopliae (Metsch.) Sorok. em adultos de cascudinho (Alphitobius diaperinus) (Panzer) (Coleoptera: Tenebrionidae) em aviários comerciais em Cascavel, PR
[Natural occurrence of Metarhizium anisopliae (Metsch.) Sorok. on adults of the lesser mealworm (Alphitobius diaperinus) (Panzer) (Coleoptera: Tenebrionidae) in poultry houses in Cascavel, PR, Brazil]
Neotropical Entomology 33 (6), 793-795
Abstract: Alphitobius diaperinus (Panzer), the lesser mealworm, is the most important pest in large-scale poultry production and is capable of harboring several types of poultry pathogens. Chickens feed readily on the beetles in infested litter and this sometimes causes nutritional problems and the weight gain may be affected. Chemical insecticides are usually applied, however beetle infestation are very difficult to control using these products. Besides, this control method can also offer risks to chicken and man. Microbial control may be a promising strategy to control A. diaperinus in poultry houses and natural occurrence of entomopathogenic fungi is very important to control the lesser mealworm in poultry houses. The objective of this work was to register the occurrence of Metarhizium anisopliae on adults of the lesser mealworm in commercial poultry houses in Brazil.

Alphitobius diaperinus (Panzer) é uma das pragas mais importantes que atacam criações comerciais de frango de corte em todo o mundo. Os insetos são hospedeiros de microrganismos patogênicos às aves, provocam ferimentos no trato digestivo das mesmas e afetam a conversão alimentar. Embora seja praticado, o controle dos insetos com inseticidas químicos é insatisfatório, na maioria das vezes, e oferece risco às aves. O controle biológico destaca-se como alternativa viável, uma vez que os entomopatógenos são inócuos a animais homeotérmicos, não oferecendo risco de contaminação às aves e ao produtor. A presença de entomopatógenos no ambiente contribui para o controle natural dos insetos-praga e, neste sentido, o presente trabalho teve como objetivo registrar a ocorrência natural de Metarhizium anisopliae sobre adultos de A. diaperinus, em aviários comerciais no município de Cascavel, PR.
