The effects of Margosan-OTM, AzatinTM and RD9-Repelin on the phytophagous mite Tetranychus cinnabarinus (Boisd.), the predacious mite Typhlodromus athiasae, and the predatory spider Chiracanthium mildei were studied and compared in laboratory experimentsr.-No toxic effect of any of these neem formulations was observed on C. mildei. Margosan-O and Azatin were not toxic to either T. cinnabarinus or T. athiasae, but RD9-Repelin was highly toxic to both the phytophagous and the predacious mite. © 1993, Springer Science + Business Media B.V..
