ASSESSMENT OF BIO-CONTROL AGENT PERFORMANCE AND INSECTICIDAL PROPERTIES OF BIO-EXTRACTS AGAINST APHID (SCHIZAPHIS GRAMINUM R.) ON WHEAT, (TRITICUM AESTIVUM L.) CROP.

An experiment was conducted on wheat variety, pasban 90, at post graduate agricultural research station (pars), university of the agriculture faisalabad during 2009-10 to study the effectiveness of bio-extracts (neem leaves extract, neem seed kernel extract, ginger extract mixed with neem leave extract and a bioagent (chrysoperla carnea) against wheat aphid. the experiment was conducted under rcbd with three replications. neem leaves extract mixed with ginger extract significantly lowered the aphid mean population 1.10 (86.08% mortality) per tiller followed by neem leave extract mixed with surfactant, where mean aphid population remained 1.95 (82.20% mortality) and neem seed kernel extract where mean aphid population recorded was 2.28 (81.27% mortality) per tiller after 24 hrs, 72 hrs, 7 days, 15 days and 22 days. chrysoperla carnea also reduced the aphid mean population to some extent and mean aphid population was 8.14 (29.49%) in comparison with check treatment after 24 hrs, 72 hrs, 7 days, 15 days and 22 days. yield data per acre showed significant differences among each treatment. data was analyzed and compared with the help of (lsd) test ≤ 0.05.
