Screening of Some Sunflower (Helianthus annuus Linnaeus Compositae) Genotypes Against Insect Pests

Muhammad Aslam and Hafeez-ur-Rahman

Abstract

Six different genotypes of sunflower (Helianthus annuus L.) were screened against Aphids (Aphis gossypii), whitefly (Bemisia tabaci), leaf miner (Phytomyza atricornis), green leaf hoppers (Empoasca spp.), painted bugs (Bagrada spp.), and sunflower seed weevil (Smicronyx spp.) at, early, growing and anthesis stages. The results concluded that SMH-9707 was found partially resistant against aphids, whereas SF-187 was found less-susceptible against leaf miner and resistant against whitefly. Suncross-24 was found highly susceptible against painted bug among all the six genotypes of sunflower. SF-187. Parsun-1 and suncross-24 were partially resistant against green leaf hoppers. SMH-9707 was found highly susceptible against sunflower seed weevil and SF-187 was found partially resistant.
