A review of the existing basis for maize stem borer IPM is given and the role of pathogens in the system is evaluated. Survey work outlining the major groups of insect pathogens is described; fungi (Beauveria bassiana and Metarhizium anisopliae), bacteria (Bacillus thuringiensis and Serratia marc...

A cotton field was used to set up an arena trial for investigating the dose transfer of oil-based ultra-low-volume sprays of Metarhizium anisopliae (Metchnikoff) Sorokin to the cotton bollworm Helicoverpa armigera (Hübner). Two doses of conidia (75 and 50 g/ha, being 3.75 × 1012 and 2.5 × 1012 co...

Deux expérimentations ont été mises en place pour étudier la réponse effet/dose de deux souches de champignons entomopathogènes, Metarhizium anisopliae, Met 31 et Beauveria bassiana, Bb 11 sur les stades larvaires de Helicoverpa armigera. Dans la première expérimentation, la souche Met 31 de M. a...

In many African countries, the misuse of chemical insecticides is questioned with the awareness of their negative effects on ecosystems and human health. There is, therefore, constant request from consumers for alternatives to chemical insecticide in plant protection. In the present study, the ef...

The present work aims to assess the pathogenicity of the conidia of six isolates of Metarhizium anisopliae and two isolates of Beauveria bassiana on Helicoverpa armigera in order to select the most promising ones for developing a microbiological product to be used in cotton fields. The pathogenic...
