abstract
Six wheat varieties were screened under Bahawalpur conditions for infestation of aphid species complex during 2014-15. Infestation of aphid population and their natural enemies were recorded during February-April 2015. Lowest population of aphid (0.13 aphids/tiller) was recorded on 6309-2013 during 3^rd week of April whereas highest population (39.97 aphids/tiller) was harbored on Shafaq-2006 at1^st week of March. A close association between the population of natural enemies and aphid was recorded. Natural enemies (ladybird beetle and syrphid fly) showed negative but non-significant correlation (-0.0078, -0.0081) respectively. No population of lacewing was observed throughout the experiment.
