Abstract: This present research work has allowed a statistical modeling for conidial adhesion and the potential fungus Metarhizium anisopliae ability to lesser the mealworm Alphitobius diaperinus control, that is an important pest of poultry production, which causes damage to the birds by the development of injuries in the digestion tract, and yet it serves as vector of many avian pathogens. The study of the host cuticle adhesion is very important, whereas the adhesion process represents a complex event, as it is the first occurrence in the pathogenhost cycle, taking place after fungus deposition on the insect, aiming the penetration phase. Adult insects of A. diaperinus were exposed to three concentrations of the fungus: 1×10 3, 1×10 6 e 1×10 9 conidia/mL, for 5, 10 and 15 minutes of exposition to each conidial concentration. In order to verify the ability control of M. anisopliae, the insects were forced to the displacement on the conidial mass growth onto PDA medium for 10 minutes, resulting in a 8,1×10 8 conidia/mL inocullum potential, and the mortality was monitored during 21 days, obtaining 74% of mortality in larvae after 48h and 50% of mortality in adults after 15 days, under fungus exposition. ANOVA has showed that there is influence and interaction between both effects: concentration and time.
