Three-dimensional reconstruction of pore canals in the cuticle of the brown planthopper

摘要

Dear Editor,The insect cuticle is a multifunctional coat that defines and stabilizes the shape of the body,appendages and internal organs,serves as a barrier against water and chemical compounds,such as insecticides,prevents infection and protects against predators(Moussian,2010).The surface of insects is covered by a lipid layer composed of diverse hydrocarbons,wax esters,fatty acids,fatty alcohols,sterols and triglycerides.Delivery of lipids to the body surface occurs through the cuticle by a nano-canal system consisting of pore canals(PC)and wax canals(WC).
