Compatibility of entomophages with biological and biorational pesticides

Severe adverse effects of chemical pesticides have driven demand for ecologically friendly technologies of plant growing with alternative pest control tactics. Traditional insecticides cause massive death of predatory ground beetles, bedbugs, coccinellids, lizards, flies and tachinid flies, parasitic trichogrammatids, ichneumonids, braconids and other useful species. Harmonized biological and chemical controls are becoming more relevant, which should include the use of beneficial entomofauna. This necessitates more data on sensitivity of entomophages to biologicals, biorational pesticides (i.e. natural substances and their synthetic analogues) and other selective chemistries. In this work, for the first time, we determined laboratory and field toxicity of several Russian and foreign conventional biologicals and chemicals for beneficial entomofauna of corn, potato and apple-tree agrocenoses. The originality of this study lies in its focus on searching commonly used biopesticides which can be integrated with entomophages in organic farming technology...
