Effects of Temperature and Humidity on the Pathogenicity of the Entomopathogenic Fungi in Control of the House Fly, Musca domestica L. (Diptera:Muscidae) under Laboratory Conditions

M. Sharififard, M.S. Mossadegh and B. Vazirianzadeh

Abstract:
The entomopathogenic fungi, Beauveria bassiana IRAN 187C and Metarhizium anisopliae IRAN 437C are the two most virulent isolates against the house fly, Musca domestica L. Effects of temperatures (15, 20, 25, 30, 35°C) and relative humidity levels of (45 and 75%) on virulence of the fungi were detected by immersion and inoculated larval bed methods for larvae and baiting method for adults. The results indicated no significant difference in larval mortality and larval cadaver sporulation at temperatures of 25-30°C and 45-75% RH for Ma 437 C. But Bb 187C caused higher mortality and cadaver sporulation at this thermal range and 75% RH. There was no significant difference in adult mortality between 20, 25 and 30°C for Ma 437 C and between 25 and 30°C for Bb 187 C. Mortality and fly cadaver sporulation were higher at the mentioned thermal range at 75% than 45% RH for both isolates. LT50 values decreased with temperature increasing between 15-30°C but increased again at 35°C. M. anisopliae caused more mortality and cadaver sporulation in wider ranges of temperature and humidity than B. bassiana. So, this isolate would be good candidate for microbial control of the house fly.
