NO SIDE-EFFECTS OF NEEM EXTRACTS ON CHRYSOPERLA-CARNEA (STEPH) AND COCCINELLA-SEPTEMPUNCTATA L

The application of AZT extract and AZT extract + neem oil does not harm eggs, larvae or adults of Chrysoperla carnea and Coccinella septempunctata. Mortality and fecundity are also not altered by neem-treatment. Only if the larvae are sprayed directly with the neem products in the laboratory, mortality increases and morphogenetic defects can be observed during adult development. Under the test conditions proposed by the IOBC/WPRS working group "Pesticides and beneficial organisms" the neem products can be considered to be harmless.
