Effect of four entomopathogenic fungi, Beauveria bassiana, B. brongniartii, Paecilomyces fumosoroseus and Metarhizium anisopliae, isolated from different host insects, was tested in the laboratory against the teak defoliator, Hyblaea puera (Cramer) (Lepidoptera: Hyblaeidae) to assess their virulence and efficiency. Five different concentrations, 2x106, 4x106, 6x106, 8x106 and 1x107 conidia ml-1were directly and indirectly applied onto third instar larvae of H. puera. All the four fungi tested under both application methods were pathogenic to H. puera with higher efficiency in direct application than indirect application. At 9 days after exposure, the mean per cent mortality obtained was 100, 93.02, 93.02 and 66.74%, respectively, for B. bassiana, B. brongniartii, P. fumosoroseus and M. anisopliae at the highest concentration of 1 x 107 conidia ml-1 in direct application. Mortality of the larvae varied according to the concentration of conidia, method of application and fungi. The lowest LC50 (1.89 x 106 conidia ml-1) and LT50 (91.18 hr) values obtained for B. bassiana in direct application showed that B. bassiana was more pathogenic to H. puera than the other three fungi.Keywords

Surveys for entomopathogenic fungi in the central forest circle of Kerala revealed the seasonal incidence of Beauveria bassiana in small pockets on Gargara mixta Buckton (Hemiptera: Membracidae) feeding on the leaves of Helicteres isora (Sterculiaceae) in the moist deciduous forests (MDF) at Vazhachal. Incidence of B. brongniartii on chrysomelid beetles (Coleoptera) feeding on teak leaves was also observed in small pockets in teak plantations. Infection was prevalent during post-monsoon months. The infection due to B. bassiana and B. brongniartii ranged from 36.8 to 100 and 45.5 to 100 per cent, respectively. The seasonal incidence of naturally occurring entomofungal pathogens, B. bassiana and B. brongniartii form small scale epizootics in nature under favourable environmental conditions. Such virulent pathogens can be exploited in pest control programmes.Keywords
