Endocrine disruptors (EDCs) are present in the environment, coming from several origins (industrial products, pesticides or even hormones). When accumulated in organisms, EDCs can lead to endocrine system dysfunctions and consequently to population decline, which could in long term impact the ecosystem’s functioning. Although in vertebrates EDC biomarkers are well established (e.g. vitellogenin), few are available in invertebrates, such as arthropods (e.g. shrimps or insects).

This work intended to study the impact of the insecticide chlordecone (CLD), widely used in French West Indies until 1993, on the concentration of the 20-hydroxyecdysone (20-HE, key hormone of the arthropod endocrine system), in the decapod Macrobrachium rosenbergii (in vivo).
