Resumo: | ABSTRACT This study aimed at evaluating the effect of the use of disinfectants and insecticides recommended for the control of pathogens and insects in poultry houses on the biological parameters of the entomopathogenic fungus Beauveria bassiana strain Unioeste 4. Disinfectants and insecticides were used at recommended concentration (RC), half the recommended concentration (0.5 RC), and twice there commended concentration (2RC). All treatments were sprayed on the fungus previously inoculated on PDA culture media. Germination, colony forming unit (CFU), vegetative growth and conidial yield were evaluated. Germination was the most affected parameter by insecticides, with reduction of up to 25% using Couro Limpo and Cypermil products. Cypermil also reduced the vegetative growth in all tested concentrations. Conidial production was reduced when products were used at the highest concentration. On the other hand, the confirmed mortality of the lesser mealworm by the fungus was not affected by none of the tested products. All disinfectants at the highest concentration reduced germination and conidia production, but did not affect fungus vegetative growth. The confirmed mortality by the fungus was most influenced by the product TH4. All tested products tested were considered compatible with the fungus.
