Toxicity of neem (Azadirachta Indica) seed kernel extracts prepared with different solvents, on the spider chiracanthium mildei


The toxicity of neem seed kernel extracts prepared with different solvents against the predatory spider,Chiracanthium mildei L. Koch, was investigated. The order of toxicity of the 4% extracts was pentane < acetone < ethanol << methanol = water (nontoxic). All extracts were nontoxic at 2.5%.
