Survey to isolate and identify the entomopathogenic fungi associated with whitegrubs was conducted in Himachal Pradesh during 2008 and 2009. The whitegrubs were collected from 14 locations and Beauveria bassiana (Bals.) was found to be associated with grubs of Brahmina coriacea (Hope) in Shillaroo and Kheradhar areas. The fungus infected grubs were observed only in higher hills of Shimla and Sirmour districts. At Shillaroo, 0.98% grubs of B. coriacea were observed to have fungal infection, whereas at Kheradhar 20.2% of the grubs showed symptoms of mycosis. When field collected grubs were reared separately location- wise in laboratory, very high percentage of mycosis (55.29%) was recorded. Kheradhar and Shillaroo populations of whitegrubs showed white muscardiane infestation in 8.72 and 5.27% of the grubs, respectively. Conidia of the fungus were globose to subglobose measuring 2.0-3.0×2.0-2.5 μm. Incubation of Shillaroo, Kheradhar, Kharapathar and Solan isolates was done at 20, 22 and 26 °C. After 15 days, the radial growth of Shillaroo isolate of B. bassiana was recorded to be 7.66 cm as compared to 7.60, 7.60 and 7.36 cm for Kharapather, Solan and Kheradhar isolates, respectively.Keywords

The efficacy of six insecticides namely chlorpyriphos 20 EC (5.0 ml/kg seed), imidacloprid 17.8 SL (5.0 ml/kg seed), clothianidin 50 WDG (3.5 g/kg seed), thiamethoxam 25 WG (3.5 g/kg seed), bifenthrin 10 EC (2.5 ml/kg seed) and chlorantraniliprole 18.5 SC (2.5 ml/kg seed) as seed treatment was tested against grubs of Melolontha indica Hope under laboratory conditions. Rajmash, Phaseolus vulgaris L. was used as test crop. The experiment was conducted in plastic trays filled with soil and farm yard manure (FYM) in 3:1 ratio. In each tray, ten third instar grubs of M. indica were released and 20 treated rajmash seeds were sown at a depth of about 5 centimeter. The results revealed that plants from chlorantraniliprole 18.5 SC (2.5 ml/kg seed) treated seeds registered least mortality (20.0 %), followed by chlorpyriphos 20 EC (5 ml/kg seed) (21.67 %) at 10 days after sowing (DAS). The grub mortality recorded in seeds treated with chlorantraniliprole 18.5 SC (2.5 ml/kg seed) and chlorpyriphos 20 EC (5 ml/kg seed) was 56.67 and 46.67 per cent, respectively at 20 DAS. Therefore, seed treatment with chlorantraniliprole 18.5 SC (2.5 ml/kg seed) could be another alternative in addition to chlorpyriphos 20 EC (5 ml/kg seed) for effective management of M. indica grubs infesting rajmash under field conditions in high hills of north western Himalaya.Keywords
