Valoración de hongos entomopatógenos para el control biológico de plagas agrícolas

Abstract

In this research note, the authors present the outcomes of a study about enzymes’activities and virulence of monosphorics cultives of the selection for mico-insecticide production. This information is used to characterize the fungi as a bio-regulator of the white fruit fly and the grasshopper. The research shows that M. Anisopliae var. Acridum cultives followed the preoduction of proteases as high (144 UP/ml), medium (56.82 UP/ml) and minor (4.27 UP/ml), and caused the death of grasshoppers following this patterns: 18 days, 11 days, 14.8 days Moreover the P. Fumosoroseus ahowed a relation between the early activity of proteases or quitinases (120-160h) and a higher mortality of inoculate nymph with higher concentrations of conidia (4.7 x 10 6 and 4.7 x 10 5 ml).
