A field experiment was conducted during the Kharif / Rabi season of 2014 in Regional Agriculture Research Station (RARS) to identify the appropriate sowing time to reduce pest incidence and to get higher seed yield. The sunflower hybrid, KBSH-53 recorded highest seed yield (12.95 q/ha and 12.05 q/ha) with reduced pest incidence and per cent foliage damage during the crop sown on first fortnight of September and second fortnight of August as compared to the crop sown on second fortnight of September, first fortnight of October and second fortnight of October.Keywords

Studies indicated the prevalence of high population of defoliator insect pests viz., Tobacco cutworm, Spodoptera litura Fabricius, cabbage semilooper, Thysanoplusia orichalcea Fabricius, Bihar hairy caterpillar, Spilarctia obliqua Walker, on sunflower during 2014. The mean population of defoliators and per cent foliage damage was recorded maximum in Basavana Bagewadi and Hungund taluk while, it was minimum in Indi and Muddebihal generally, the population of defoliator insect pests occurrence on sunflower crop was very low during seedling stage and it was gradually increased during vegetative stage of the crop and reached a peak occurrence during reproductive stage. Maximum population of coccinellids and spiders were recorded in Basavana Bagewadi and Hungund taluk whereas, minimum Indi, Muddebihal and Sindagi taluk, respectively.Keywords

Studies showed the evidences of high populations of pests on sugarcane viz., early shoot borer (Chilo infuscatellus Snell), ischolar_main grub (Holotrichia serrata Fabricus), woolly aphid (Ceratovacuna lanigera Zehnter), scale on sugarcane during 2014.Generally, the incidence of woolly aphid, scales and natural enemies was not appeared during seedling stage of crop since it require cold climate and high relative humidity (80-95) and moderate temperature (19 to 30°C). Therefore more population density of woolly aphid, scales and natural enemies was gradually increased during vegetative stage.Roving survey indicated that, higher dead heart percent damage of early shoot borer was recorded in Athani while, lower population of early shoot borer was noticed in Vijayapur taluka. The lowest population of ischolar_main grub was recorded in Vijayapur taluk while the highest population of ischolar_main grub was recorded in Athani taluka during the Seedling stage. Similarly, the lowest population of woolly aphid was recorded in Muddebihal taluk while the highest population of woolly aphid was recorded in Athani taluka. The higher population of scales was recorded in Basavana Bagewadi talukas while lower population of scales was noticed in Bilagi taluka. Maximum population of Micromusigoratus and Dipha aphidivora was recorded in Jamakhandi and Basavana Bagewadi taluks, while minimum population of M.igoratus and D. aphidivora was recorded in Bilagi and Muddebihal talukas.Keywords
