摘　　要：植物体表化合物是介导植食性昆虫寄主接受行为的重要因子,是潜在的害虫行为调节剂。植物体内的化合物可以渗透到叶表成为植物信息化合物。植物体表的可溶性糖、氨基酸、长链脂肪族烷烃以及某些次生化合物能提供植物种的或营养的信息,被昆虫的接触化学感受器感受。植食性昆虫受接触化合物的兴奋性信息与抑制性信息的平衡调节。文后还介绍了植物体表化合物组成及其接触化学感受的研究方法。The surface compounds from plants,which might be potential regulators of insect behaviors,are crucial factors for the mediation of host acceptance by phytophagous insects.Phytochemicals in the plants might be available in plant surface by leaching.It has revealed that the species-specific and nutrition information could be perceived by the contact chemoreceptors with surface compounds such as soluble sugars,amino acids,longer chain n-alkanes,and certain secondary metabolites.The process of host acceptance is regulated by the balance of stimulatory and deterrent input to the chemoreception neurons.The methodology for analysis of surface compounds from plants and for measurement of contact chemoreception of phytophagous insects was stated as well in the present review.
