Abstract
The effects of a commercial neem oil titolated in azadirachtin at 10,000 ppm on the phytophagous mite Tetranychus urticae Koch were investigated in laboratory trials. The material provoked a high mortality on the post embryonic developmental stages of the mite when citrus leaves were used as substrate, while mortality was lower (40%) on bean leaves. Neem oil caused a high mortality of young females (100%) and also a remarkable reduction of the oviposition rate in contaminated females (from 10.9 to 93.5%). The two choice-tests, carried out in order to evaluate the repellent effect of the material, showed that neem oil has long term repellent properties.
