Field experiments against ischolar_main grubs in sugarcane and arecanut were laid out at Agricultural Research Station, Sankeshwar, Belgaum district and Sugavi village in Sirsi taluk of Uttar Kannada district of Karnataka, India, respectively. Application of Metarhizium anisopliae (Metschnikoff) Sorokin (Ma-1) against sugarcane white grub, Holotrichia serrata (Hope) at 1x1013 conidia ha-1 was found next best to chlorpyriphos and registered 91.95% reduction in grub population (60 DAT). The highest cane yield was recorded when M. anisopliae was applied @ 1x1013 conidia ha-1 (94.21t ha-1) and it was on par with chlorpyriphos @ 3lit a.i. ha-1 (93.76t ha-1). However, incremental benefit-cost ratio (IBCR) was high with higher dose of mycopathogen (7.83) followed by drenching of chlorpyriphos @ 2lit a.i. ha-1 (6.09). Application of M. anisopliae (Ma-1) against arecanut white grub, Leucopholis lepidophora (Blanchard) @ 2x1013 conidia ha-1 recorded 77.10% reduction in grub population and was next best to chlorpyriphos drenching @ 1 lit. a.i. ha-1 (96.80%).Keywords

Evaluation of food grains for suitability as substrates for mass production of the fungus, Acremonium zeylanicum (Petch) W. Garns and H. C. Evans revealed that the spore count increased with increase in duration of incubation period after inoculation till harvesting. Rice and sorghum grain served as potential substrates for conidial production of A. zeylanicum which yielded 9.15 × 108 and 8.33 × 108 conidia/g of substrate, respectively, 15 days after inoculation. Maize and bajra were next best alternatives. However, the other materials like ragi, bengalgram and wheat did not serve as efficient food source for mass production of the fungus.Keywords

Nomuraea rileyi (Farlow) Samson is a potential entomopathogenic fungus against lepidopteran pests. This was formulated as wettable powder and oil-based formulations to increase its efficiency in the field by using different carrier materials and oils and these were evaluated in the laboratory against two important noctuid pests, Helicoverpa armigera (Hubner) and Spodoptera litura (Fabricius). Among the wettable powder formulations of N. rileyi, viz., bentonite + glucose (7:1), talc + glucose (7:1), bentonite + sucrose (7:1) and talc + sucrose (7:1) recorded 87.0, 74.0, 72.0, 83.0 and 75.0 per cent mortality in S. litura and 79.0, 70.0, 66.0 and 88.0 per cent in H. armigera, respectively. The oil-based formulations (tank mix) with pongamia oil, sunflower oil, sesame oil and groundnut oil recorded 74.0, 90.0, 83.0 and 87.0 per cent mortality in S. litura and 73.0, 89.0, 87.0 and 87.0 per cent in H. armigera, respectively.Keywords

The fungus, Acremonium zeylanicum (Petch) W. Gams and H.C. Evans, was found infectious to sugarcane woolly aphid, Ceratovacuna lanigera Zehntner and caused differential mortality of different instars at varied concentrations. Studies on the efficacy of the entomopathogenic fungus revealed that the mortality of aphids increased with increase in concentration and time of application. First instar nymphs showed the highest mortality (92.5%) at 1x1010 conidia 1-1 and as the stage of the insect advanced, the mortality rate declined. On the contrary, lower mortality of aphids was recorded at 1x104 conidia 1-1 after 10 days of application.Keywords
