ABSTRACT The fungal isolates collected from Karaikal were tested against seven insect pests using different inoculation methods viz., spraying, crawling and dipping. Dipping method was found to be highly effective (82.50 percent) to coccinellids followed by spraying and crawling methods (48.75 and 13.75 per cent ). Larval mortality of spotted pod borer in pulses is more with spraying method (85.00 per cent). Isolate of Fusarium moniliforme on Green Leaf Hopper (GLH) recorded 90 per cent mortality with spraying method. Isolate of F. pallidoroseum against third instar of rice leaf folder caused 82.50 per cent mortality in spraying method followed by crawling (62.5) and dipping methods (42.5 ). Among the three methods, spraying method was considered to be superior. Isolate of F.pallidoroseum against third instar larvae of E. vittella recorded 50.00, 40.00 and 90.00 per cent mortality with spraying, crawling and dipping methods respectively. In general spraying method was found to be superior .
