abstract
The present study was conducted for screening of some popular varieties of sunflower viz., Armoni, Hysan-33, NK-Singi, S-278 and US-666 against sucking pests namely jassid, aphid, whitefly, thrips, dusky cotton bugs and predators namely ladybird beetle and green lacewing at the research farm area of The Islamia University of Bahawalpur, Pakistan during spring, 2014. According to analysis of variance, there was significant difference in population of jassids on different varieties. Significantly more population was observed in US-666 (20.36) and lowest in S-278 as 16.43 (P<0.05). Significant difference was not found in population of other pests and predators in different genotypes. However significant difference in the populations of these pests and predators was found on different dates of observations. On harvesting yield, maximum yield was 963 Kg/hec on variety S-278 followed by NK-Singi (900 Kg/hec), Hysun-33 (808 Kg/hec), US-666 (767 Kg/hec) and Armoni (699 Kg/hec) in descending order.
