Toxicity and Lethal Effect of Greenhouse Insecticides on (Coleoptera: Coccinellidae) as Biological Control Agent of (Hemiptera: Aphididae).

Deltamethrin and imidacloprid are commonly used insecticides for controlling sub-sucking insects in greenhouses. However, their application may cause sublethal effects on the aphid coccinellid predator (Coleoptera: Coccinellidae). Here, we study (i) the toxicity and the effect of two sublethal doses (LD and LD) of deltamethrin and imidacloprid on in a laboratory microcosm and (ii) the residual toxicity of the two insecticides in a greenhouse.

Toxicity and Influence of Sublethal Exposure to Sulfoxaflor on the Aphidophagous Predator (Coleoptera: Coccinellidae).

(Goeze), the variegated ladybug, is a predator of many insect pests, especially aphids. Sulfoxaflor is a chemical insecticide that can be used to control many sap-feeding insect pests, for instance, plant bugs and aphids, as an alternative to neonicotinoids in different crops. To improve the combination of the and sulfoxaflor in an IPM (integrated pest management) program, we studied the ecological toxicity of the insecticide to the coccinellid predator at sublethal and lethal doses.
