Influence of some neonicotinoid insecticides on the predator [Coccinellidae: Coleoptera] Stethorus gilvifron

ABSTRACT

Laboratory and field studies were undertaken to investigate the influence of three insecticides belong to Neonicotinoids group [Actara 25WG [Thiamethoxam],Conquest 20SP [Acetamprid],Confidor20 SC, 5G [Imidacloprid]] and one organophosphorus insecticide Hostathion 40EC on the predator S. gilvifron. Results have indicated that the Neonicotinoids insecticide were less harmful against all stages of the predator compared with hostathion which gave high percent of mortality on all stages following direct foliar application. Actara was the most promising insecticide material particulary when applied to the soil, indicating the feasibility of integrating with the coccinellid predator in the control program
