Heteroptera Coreidae (Anoplocnemis curvipes, Homoeocerus pallens, Leptoglossus membranaceus et Pseudotheraptus devastans) : Four crop pest and their wild host plants

Heteroptera Coreidae are all phytophagous insects.They are both meet on cultivated and wild plants.The objective of this study was to identify the Coreinae on the different crops grown in Côte d'Ivoire, evaluate the damage on these plants and identify wild plants that serve as their refuge in the absence of crops.The samplings were carried out in areas cultivated across different regions and in the reserve of Lamto.The insects were captured using a sweep net, a harvesting cage and threshing technics.The catching were once a week in different areas during one year.The results indicate that among Coreinae harvested, Anoplocnemis curvipes, Homoeocerus pallens, Leptoglossus membranaceus and Pseudotheraptus devastans were the mostly encountered on the prospected plants.The polyphagous species was A. curvipes with over than 60 host plants identified.Gossypium barbadense was the most infected by the Coreinae, followed by Cocos nucifera and Vigna unguiculata.The damage caused by these insects on the plants and the yields are function of their number in the field.
