The aim of presented studies was to determine the toxicity of some pesticides to predatory bugs Orius laevigatus and Macrolophus caliginosus. The results of performed studies revealed that the tested predatory bugs were sensitive to insecticide Kohinor 200 SL (imidacliprid) and fungicide Falcon 460 EC (spiroksamina, tebukonazol, triadimenol) in laboratory tests. The pesticides Abarex 018 EC (abamectyna) and Blotch 500 SC (chlorotalonil) showed to be selective for O. laevigatus and M. caliginosus. These pesticides might incorporated into IPM (Integrated Pest Management) programmmes of greenhouse crops.
