The effects of Neemgard, an acaricidal and fungicidal formulation obtained from neem (Azadirachta indica) seed kernels, on the phytophagous mite Tetranychus cinnabarinus, the predacious mite Phytoseiulus persimilis, and the predatory spider Chiracanthium mildei, were investigated in laboratory experiments. Neemgard was highly toxic to T. cinnabarinus but had no toxic effect on C. mildei or P. persimilis. Another neem formulation - the insecticidal Neemix 45 - caused conspicuous repellency, but no morality, in T. cinnabarinus.
