A. AmjadM. Shafiullah MasihR. 3200033Weekly data for population trend of Nysius inconspicuus Distant. showed that its attack was initiated in May at late seed development stage and remained until sunflower harvesting. The average number of bugs was 0.15 per head in the second week of. May. A sharp increase was observed in its population and a maximum number (216.5 bugs/plant) was recorded in the. Jest week of June at the time of harvest during spring, 1994. Dimecron 100 SCW at 300 mliacre, Paramat 50 EC at 450 ml/acre, Thiodan 35 EC at 700 mliacre and Tamaron SL 100 at 450 ml/acre were tested for the control of dusky bug, N. inconspicuus Distant. on sunflower during spring 1994. They effectively controlled the bug population and saved the yield significantly. There was no significant difference for dusky bug mortality among the tested insecticides. The bug control increased crop yield and percent oil content significantly compared to check. Dimecron 100 SCW gave the best result regarding the yield (2205 kg ha1) and oil content (45.33%) followed by Paramat 50 EC (1867 kg ha1 and 44.71%), Thiodan 35 EC (1781 kg ha1 and 45.17%) and Tamaron SL 100 (1727 kg ha1 and 43.30%), respectively. The effective control is achieved when the crop was sprayed at 10-day interval.]]>Birtles, D.B., B.C. Waddell and J.H.
