description

Acetone extracts of Annona cherimola Mill., Melia azedarach L., Artemisia absinthium L. and Quassia spp., were tested in laboratory trials on young females of Tetranychus urticae Koch (Acariformes,Tetranychidae). In the post-infestation tests, extracts of Melia and Annona caused a high mortality of the target females (84% and 96% for Melia and Annona, respectively) after 24 hours and 100% for both extracts after 48 hours. On the other hand Artemisia extracts caused 84% mortality of females after 10 days even if the oviposition rate was statistically lower than in the controls (2.5 and 6.7 eggs/female/day for Artemisia and controls, respectively).
