Description

The study was conducted on the wheat crop for the management of aphids in the research area of University of Agriculture, Faisalabad during 2009. Fedding efficacy of various larval instars and adult of C. Septempunctata L. was studied under laboratory conditions of Biodiversity and Biosystematics Lab. Department of Agri- Entomology university of Agriculture, Faisalabad. The results revealed that the fourth larval of C. Septempunctata L. consumed more aphids (36.67) followed by third (30.32), second (16.47) and first instars (2.10) respectively. Whereas the adult of C. Septempunctata L. was found very much voracious and consumed 74.07 aphids. All the insecticides were statistically equal, in controlling the population of aphids. However Advantage caused more mortality followed by Acelan, Imidacloprid, Black Warent and Rigorous in field conditions. All the insecticides were also tested against aphid in controlled conditions of labs. The effects of these insecticides were statistically equal. However However Advantage caused more mortality followed by Acelan, Imidacloprid, Black Warent and Rigorous in field conditions.
