Abstract 1. Ecological studies: Occurrence of spider families collected from broad bean and cotton crops: The percentage of spider families and occurrence of their species their families during two successive years. Seasonal abundance of the three pests, the cotton leafworm, aphids and phytophagous mite and their associated predatory spiders. Association between the three pests and spider families. Average number of spiders’ predators and their families from broad bean and cotton plants during two successive years. 2. Biological studies: - Laboratory studies on the biology of the spider as a potential natural agent in biological control. 3. Toxicity of some alternative pesticides on adults (females and male): - Effect of alternative pesticides, local petroleum oil (KZ oil 95% EC), microorganism product (Streptomyces avermitilis) (Vertimec 1.8% EC), and plant extract (Piper nigrum) on predatory spider. 4. Biochemical studies to investigate the effect of nutrition and alternative pesticide on total protein and protein bands in adult spiders. |
