| Abstract | ||
| Ten entomopathogenic fungi were recorded naturally associated with cabbage aphid. They were five hyphomycetes and five Zygomycetes (four Entomophthorales & one Mucorales). Six genera showed good epizootic beside their safety to plants. They were: Panadora neoaphidis, Conidiobolus obscurus, Neozygites fresenii, Entomophthora planchoniana, Cladosporium cladosporioides and Verticillium lecanii. Efficiency of these entomopathogenic fungi against Brevicoryne brassicae was evaluated under laboratory conditions. P. neoaphidis was the most efficient with LC50: 2.5417x 102 conidia/ml then, V. lecanii which showed LC50 of 3.052x102 conidia/ml followed by C. obscurus which showed LC50 of 3.161×102 conidia/ml, then, N. fresenii which recorded LC50 of 8.536×102 conidia/ml. Then, C. cladosporioides showed LC50 of 23.271×102 conidia/ml, then at last comes E. planchoniana with LC50 of 70.593×102. | ||
