Two isolates of Metarhizium anisopliae were selected based on virulence in order to clarify the relation-ships between adhesion and virulence of conidia to Thrips palmi. LC_<50> values (CFUs/ml) of M. anisopliae UZ and OE-2 to adults of T. palmi were 7.5×10^5 and 2.5×10^5, respectively. The conidia of M. anisopliae OE-2 bound to the adult cuticles more effectively than conidia of M. anisopliae UZ. This suggests that the virulence of M anisopliae to T. palmi is correlated with the number of adhereded conidia. The conidial detachment value, conidial germination ratio on the adults and LD_<50> values (number of conidia/adult) were also compared between the two isolates. These experiments also demonstrated that conidial development after adhesion affected the virulence of M. anisoplae to T. palmi.
