Ocorrencia de metarhizium anisopliae (Metsch.) Sorok. em adultos de cascudinho (Alphitobius diaperinus) (Panzer) (Coleoptera: Tenebrionidae) em aviarios 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
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.
