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...
