| ABSTRACT Beauveria bassiana is naturally found in broiler chicken houses, and has been shown to be active against the lesser mealworm, Alphitobius diaperinus. The effectiveness of soil application of B. bassiana in emulsifiable oil-type formulation (Unioeste 4 isolate) to control the lesser mealworm in commercial poultry house was evaluated. The fungus was applied to the dirt floor of poultry house at 4.2 × 109 conidia/m2 (treated aviary) and the insect population was assessed before and 96, 146 and 216 days after application (DAA). In the control aviary, no treatment was performed to control those insects. Molecular techniques were used to confirm the presence of the fungus in dead A. diaperinus. Significant treatment effects were observed, with 56% and... |

| Global poultry production is plagued by a wide variety of arthropods. The problems associated with their chemical control have led to an increasing search for control alternatives, and entomopathogenic fungi seem to be a promising strategy. Despite the large number of insects and mites considered as important pests in animal production, studies on the use of entomopathogenic fungi for their control are still scarce compared with agricultural pests, particularly in Brazil. This article reviews some damages and control aspects of the main arthropod pests that affect Brazilian poultry production, including house flies, lesser mealworms, and feather mites, by the use of the entomopathogenic fungi Beauveria bassiana and Metarhizium anisopliae. Studies published... |

| ABSTRACT Poultry red mite Dermanyssus gallinae is a cosmopolitan and hematophagous species commonly found in layer houses around the world. Poultry mite infestations may cause anemia, stress, low body weight and egg production, and mortality. Mite control is typically based on chemical products, but they are not effective and leave residues in eggs; therefore, alternative control methods, such as entomopathogenic fungi, need to researched. This study aimed at evaluating, in the laboratory, the activity of Brazilian isolates of entomopathogenic fungi against D. gallinae. The mites were collected from a commercial layer house and were sprayed with conidial suspensions (1 × 108 conidia/mL) of five isolates of Beauveria bassiana and Metarhizium anisopliae. All... |
