1 Effective biological pesticides based on oil formulation of deuteromycete fungal spores have been developed for use against locusts and grasshoppers. The isolate IMI 330189 of Metarhizium anisopliae (¯avoviride) var. acridum has been registered, extensively ®eld tested and its operating charact...

A mixture of lambda‐cyhalothrin (lambda‐cyhalothrin: chemical insecticide) and Metarhizium anisopliae (flavoviride) var. acridum Driver and Milner, an entomopathogenic fungus (bioinsecticide) was used for grasshopper control in Mali. An oil‐based formulation of Metarhizium anisopliae (flavoviride...

Trials on the use of Metarhizium flavoviride Gams and Roszypal conidia in oil-based formulation for the control of grasshoppers, particularly Hieroglyphus daganensis Krauss, in Malanville, north Benin, are described. Preliminary work examined sprayer types, application rate, and time of applicati...

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...

Inventory of insects associated with Jatropha curcas L. (Euphorbiaceae) was conducted from June 2011 to May 2012 at 5 sites in southern and central Benin. Thirty-two major insect pests and 14 natural enemies, including 6 parasitoids and 8 predators, were recorded. The most important phytophagous ...

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...
