BACKGROUND The recent outbreak of bluetongue virus in northern Europe has led to an urgent need to identify control measures for the Culicoides (Diptera: Ceratopogonidae) biting midges that transmit it. Following successful use of the entomopathogenic fungus Metarhizium anisopliae against larval stages of biting midge Culicoides nubeculosus Meigen, we investigated the efficacy of this strain an...

Qinghai-Tibet Plateau and Gansu Corridor of China with distinct geographic and climatic conditions are remote and less disturbed by humans, in which are likely to find some new strains of fungal entomopathogens against B-biotype whiteflies that is a very important invading pest worldwide. In this research, nineteen strains among six species of entomogenous fungi were isolated from the soil samp...

There is growing interest in the use of entomopathogenic organisms to control leaf-cutting ants (Hymenoptera: Formicidae: Attini). However, the way leaf-cutting ants react as a colony to biohazards is poorly understood. We investigated the effects of Metarhizium anisopliae (Metschnikoff) (Deuteromycotina: Hyphomycetes) applied to the foraging arenas of mini-nests (queenless sub-colonies) of the...

En condiciones de laboratorio se evaluó la eficacia cuatro formulados a base Bacillus subtilis, thuringiensis var kurstaki, Metarhizium anisopliae, Beauveria bassiana más un testigo (agua destilada) sobre los estados desarrollo larval plaga Leptophobia aripa Boisduval. Se colectaron 15 larvas por cada estadio, colocadas en grupos 5 placa para total cinco tratamientos con tres repeticiones. Como...
