Maize Media Enhance the Conidia Production of Entomopathogenic Fungi Lecanicillium lecanii also Its Effective to Control the Weevil Cylas formicarius (Fabricius) (Coleoptera: Brentidae)

The growth of entomopathogenic fungi Lecanicillium lecanii is strongly related to the media in increasing sporulation, enhancing its effectiveness infecting target pests. This study aims obtain L. propagation with highest conidia production, and increased virulence on Cylas formicarius . first stage alternative selection consists of: Potato Dextrose Agar; maize, rice; bran. second infectivity best 5 treatments replications: synthetic insecticide (C + ); distilled water (C-); 10 7 conidia/ml; 8 9 conidia/ml. results show that colony rate (1.15 mm) Maize media, density (4.2 x 10⁸ conidia/ml) not significantly different from PDA (1.3 conidia/ml). germination (74.31%) weight (1.10 g) Rice maize (1.45 g). L.lecanii affect mortality C. (74%) substantially at a concentration LC 50 value obtained 2.6 10⁷ Thus, can be an medium for mass
