Evaluation of pathogenicity of certain mitosporic ascomycete fungi to the house fly, Musca domestica L. (diptera : muscidae)‎

Abstract EN

The virulence of five fungal strains, Acremonium cephalosporium, Aspergillus niger, Penicillium chrysogenum, Trichoderma viride, and Verticillum albo-atrum by application of 108 conidia mL1 to larvae and adults of house flies, Musca domestica was determined.

A.

niger produced the highest percentage of mortality to larvae, 85.1 ± 1.60, and adults, 98.2 ± 3.10, of house flies.

Topical application of the fungal strains to larvae showed concentration-dependent response and caused mortality ranged between 41 % and 83 % with LT50 values varying between 5.22 and 7.81 days.

The highest percentage of mortality, 83.9 ±3.52, was produced by 107 conidia mL1 of A.

niger with LT50 5.22.

The lowest mortality percentage, 41.2 ± 3.00 with LT50 7.81, was produced by 105 conidia mL1 of V alboatrum.

On the other hand, the highest percentage of mortality to adults of house flies 97.3 ± 3.52was produced by 107 conidia mL11 of A.

niger with LT50 3.49.

While the lowest mortality percentage, 59.1 ± 2.38 with LT50 6.91, was produced by 105 conidia mL 1 of V.

albo-atrum.
