Bioeffects of the entomopathogenic fungi Beauveria bassiana (Bals.) on mushroom fly Bradysia ocellaris (COMS.) (Diptera: Sciaridae) [electronic resource].

Includes reference.

Laboratory experiments were carried out to determine the bioeffects of an isolate of entomopthogenic fungi Beauveria bassiana (Bals.) and Biofly a commercial product of B. bassiana, on the 1st instar larvae of mushroom fly. Bradysia ocellaris (coms), The bioactivity of B. bassiana was tested, using five concentrations of B. bassiana on some biological criteria of the mushroom fly, by calculating LC₅o values after three and seven days of treatment. Results indicated that the mortality rates percentage increased with the increase of the concentrations used and the period after treatment. The highest percentage of mortality occurred within the first seven days following treatment. Statistical analysis of the obtained larval-pupal and adults period and weight revealed significant differences between treated and nontreated insects.
