One purpose of the sustainable agriculture is not having adverse effects on the beneficial insects. Presently non target insects are still exposed to high doses of various pesticides used on various crops. The major beneficial insects are domesticated pollinators such as honeybee. Regarding this one, no direct correlation between diffuse mortality, sublethal effects or colony collapse disorder and pesticides is clearly demonstrated. Nevertheless, studies have shown the complexity of the combined toxic effects between pesticides (principally synergy between insecticides and fungicides), their incidence on the insect health and their putative relationship with insect pathogens (bacteria, virus, fungi or mites). That leads to consider that the reduction of pesticides (qualitatively and quantitatively) is needed to prevent non target insects from excessive mortality even if other causes of over mortality exist.
Key words: sustainable agriculture / beneficial insects / toxic effects between / pesticide
