Abstract
Three isolates/strains of Metarhizium anisopliae were isolated from swarmed adults of Coptotermes heimi at No-shehra Virkan, Gujranwala. The exposure methods of these isolates against termites included soil substrate and filter paper treatment with different concentrations (1 x 10(4), 1 x 10(6), 1 x 10(8), 1 x 10(10) conidia mL(-1)) of conidial suspension. LT50 for three strains of M anisopliae on C heimi were comparatively more (65-106 h) in soil than on filter paper (50-83 h). There was significant difference in different concentrations of all strains of M. anisolpliae (p<0.05).
