Patogenicidade de Metarthizium anisopliae var. anisopliae, Metarhizium flavoviride var. flavoviride e Beauveria bassiana a Nasutitermes coxipoensis (Isoptera: Termitidae) em cana-de-açúcar e compatibilidade com inseticidas químicos

Abstract (Summary)
Metarhizium anisopliae var. anisopliae, Metarhizium flavoviride var. flavoviride and Beauveria bassiana have proved action against several species of insects. These fungi can infect the termites naturally. The action of these fungi on Nasutitermes coxipoensis was evaluated in laboratory and conidia production in dead insects was quantified. The compatibility of M. anisopliae var. anisopliae reisolated from N. coxipoensis with insecticides fipronil, imidacloprid and endosulfan wasdetermined through germination, colonial growth and sporulation parameters. Infective doses by direct contact for each one of the fungi were determined by using bioassays. The compatibility of reisolated with the insecticides was determined testing five concentrations of products. Results showed that method of inoculation by direct contact of insects with fungus culture was efficient. M. anisopliae var. anisopliae showed higher virulence than M. flavoviride var. flavoviride and Beauveria bassiana. M. anisopliae var. anisopliae presented highest conidia production on dead N. coxipoensis . The compatibility study showed that fipronil was considerated compatible in following concentrations: 0,20 amp;#956;m, 0,50 amp;#956;m and 1,00 amp;#956;m and incompatible in 2,00amp;#956;m and 5,00amp;#956;m concentration and imidacloprid and endosulfan were compatible and they didn?t affect evaluated parameters
