摘　　要：采用制作玻片标本和扫描电镜技术研究了康氏粉蚧Pseudococcus comstocki(Kuwana)在不同发育阶段的显微形态特征及蜡泌物的超微形态。结果表明:三格腺是康氏粉蚧最主要的腺体,随着虫体的发育,数量增多,分布变广,每个腺孔分泌一根蜡丝,覆盖体表;管腺只在特定的时期分泌长的空心蜡管构成卵囊;多格腺分泌多棱形卷曲的小蜡丝粘附在卵粒上,防止其相互粘连。The microscopic characteristics and ultrastructure of wax secretion by different life stages of the mealybug Pseudococcus comstocki （Kuwana） were observed under a light microscope and a scanning electron microscope. This revealed that the main pores of P. comstocki are trilocular pores, which increase in number and become more widespread with development. Furthermore, each wax filament is secreted from individual locular pores distributed over the dorsum of body. Tubular ducts produce long, hollow filaments that serve as a framework for the ovisac structures at a distinct time during development. The egg surface clings to a thin layer of small curled and multi-ridged wax filaments produced by multilocular pores, which prevents them sticking to each other.
