Abstract
The effects of Neemark, commercial preparation obtained by neem
(Azadirachta indica) seed kernels extract, on Tetranychus urticae Koch and Phytoseiulus
persimilis Athias-Henriot were tested on bean leaf discs treated with different
concentrations in laboratory experiments. Neemark can be considered moderately
toxic for T. urticae but highly toxic for young stages and adults of Ph.
persimilis at 3% and 5% concentrations. Also were investigated two new vegetable
oils formulations 7094 and 1294 D/S on T. urticae in concentrations 0.5%,
1 % and 2% caused high toxicity and promise for the near future an alternative
solution in the control of tetranychids in greenhouse culture and field crops.
