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 Research presented in this book was conducted in the Bio systematic laboratory in the Department of Agri. Entomology, University of Agriculture Faisalabad. Collection of Aedes albopictues was done on weekly basis from the botanical gardan of the University and from different localities of Faisalabad by placing tires, collected mosquitoes were rearded in the insectry. Fifteen plants and Thirteen citrus cultivars were used as larvicide. Soxhelt apparatus was used for extraction of oil by using different plant parts. Ether was used as solvent, 30 late 3rd and early 4th instar larvae were...

Pesticides have been used to control these pests but none has yielded better cost and benefit ratio due to increasing hazards related to human life, domestic animals and environment. Recent trends in cotton production have been to minimize the use of pesticides and ultimately control the pest by better management practices (BMPs). Keeping in view these critical issues the experiment was conducted during May-October 2009 under randomized complete block design (RCBD) with five treatments, biological control agents (T1), foliar applications of botanical Neemosal, azadirachtin+salannin...

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...
