The Entomopathogenic Fungi and for Management of the Melon Fly : Pathogenicity, Horizontal Transmission, and Compatability with Cuelure.

In the laboratory, the pathogenicity of thirteen isolates of (Metschnikoff) Sorokin and two isolates of (Balsamo) Vuillemin against the melon fly (Coquillett) were assessed by exposing adults to 0.3 g of dry conidia (~3 × 10 conidia) of each isolate for 5 min and monitoring mortality for up to 5 days. Compatibility with a male pheromone, cuelure, (4-(p-acetoxyphenyl)-2-butanone), was determined by testing conidial germination and germ tube growth of the most promising isolate, ICIPE 69, in the presence of cuelure at different temperatures.

Performance of Three Isolates of and Their Virulence against under Different Temperature Regimes, with Global Extrapolation of Their Efficiency.

The performance of entomopathogenic fungi in pest control is usually affected by both biotic and abiotic factors. This study aimed to determine the effects of various temperatures (15, 20, 25 and 30 °C) on conidial germination, mycelial growth and conidial density and virulence to the melon fly of three selected isolates of The three isolates, ICIPE 18, ICIPE 30 and ICIPE 69, had previously been selected in laboratory bioassays. Percentage mortality by the three isolates ranged between 16.
