This book describes number of aphid species attacking wheat varieties, population dynamics of aphid's species by collecting them from the field by using different collection techniques, and examine them in the laboratory under the microscope for the sake of species identification. The effect of abiotic factors on aphid's population was also determined. Four species of wheat aphid viz., Schizaphis graminum, Sitobion avenae, Rhopalosiphum padi and Rhopalosiphum maidis were identified on the basis of their taxonomic characters out of which S. graminum was most destructive. SARC-2 and SARC-8 were...

This book describes the entrance of Cr (III) into the food chain of silkworm from mulberry plants irrigated using Cr (III) containing synthetic effluents during the year 2010 at Sericulture Laboratory in Agricultural Entomology Department. The objective of the study was to evaluate the accumulation of Cr (III) in soil, mulberry leaves, silkworm larvae, silk glands and feaces and to observe the effects of this accumulation on the growth of silkworm larvae and silk yield. The soil, plant, silk glands silkworm and their excreta were sampled to determine Cr. (III) amount using Atomic ...

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...
