BACKGROUND: Endosulfan is a semi-permanent pollutant that can be transported long distances through the atmosphere. Although phased out in many countries, it is still used in some highly populated areas and thus greatly contributes to environmental pollution. It can impact non-target species such as Leptopilina boulardi, a hymenopteran parasitoid that is beneficial because it controls the populations of its host. Only one L. boulardi egg can successfully develop in its host, a Drosophila larva. Consequently, parasitoid females generally lay only one egg per host, except when they are infected by a virus (LbFV) that triggers superparasitization behavior (laying more than one egg per host). The effects of an LC 20 of endosulfan on the parasitization behavior of two L. boulardi strains, one infected by LbFV and the other not, were evaluated. laid per host (i.e., the rate of superparasitization) irrespective of whether the strain was infected by LbFV or not. CONCLUSIONS: Recent research has shown that the organophosphorus insecticide chlorpyrifos induced superparasitization in parasitoid females. Both endosulfan and chlorpyrifos are neurotoxic and induce nervous system hyperstimulation. The fact that endosulfan does not trigger superparasitization, whereas chlorpyrifos does suggests that this effect is due to the specific pathway impacted by chlorpyrifos, the cholinergic nervous pathway. The consequences of these results in the context of awareness of environmental pollution by pesticides are discussed. RESULTS: Endosulfan decreased the number of host larvae parasitized by both strains (decreased rate of parasitization) but had no impact on the number of eggs

“…For examples, insecticides have been shown to interfere with the sexpheromonal communications of the parasitoid wasp Trichogramma brassicae (Delpuech et al, 1998a(Delpuech et al, , 1999a(Delpuech et al, , 2012(Delpuech et al, , 1998b(Delpuech et al, , 1999bDupont et al, 2010). Insecticides have been shown to interfere with the kairomonal communications (Delpuech et al, 2005;Komeza et al, 2001) and circadian rhythms (Delpuech et al, 2015) of Leptopilina parasitoids. In this work, it is shown that the neonicotinoid imidacloprid does not modify the parasitism behavior of L. boulardi, contrary to what was expected.…”

Organochlorine pesticide pollution of surface water, groundwater, soil, sediments, and air has been recognized as a major problem in many countries because of the persistence in different environments and the consequent potential adverse health effects. This report presents a review of literature on organochlorine insecticide of endosulfan, which has been used extensively for agricultural purposes. It summarizes information on nomenclature, physical-chemical properties, production, metabolism, degradation, distribution in the environment, toxicity, regulation, and technologies for the treatment of water and soil contaminated with this pesticide.
