The effects of neem seed kernel extracts from different solvents on the predacious mitePhytoseiulus persimilis Athias-Henriot and the phytophagous miteTetranychus cinnabarinus (Boisd.) were compared. All extracts were much more toxic to the latter pest than to the former. Using the respective LC50 for the two species, the toxicity index (LC50Phytoseiulus/LC50Tetranychus) was found to be 3 for the methanol, 4 for the ethanol, 23 for the acetone, and 58 for the pentane extract. The order of… CONTINUE READING
