摘　　要：美洲斑潜蝇LiriomyzasativaeBlanchard和南美斑潜蝇Liriomyzahuidobrensis(Blanchard)是我国的2种重要入侵性害虫。本实验室在标准化流程下饲养了48(L.huidobrensis)-160(L.sativae)个世代的稳定实验种群。美洲斑潜蝇的实验种群需要较大的繁殖规模(>100对)才能保持群体的稳定性。2种斑潜蝇4个发育阶段的形态特征和幼虫为害特征差别明显。南美斑潜蝇的发育历期比美洲斑潜蝇长,总产卵量低于美洲斑潜蝇,但产卵历期明显长于美洲斑潜蝇。这可能是南美斑潜蝇较之容易繁殖的重要原因。该实验种群的建立为物种驯化、寄主选择性、抗性筛选及其它生理学、生态学等诸多研究打下基础。Leafminers, Liriomyza sativae Blanchard and Liriomyza huidobrensis （Blanchard） are two of the most important invasive pests in China. Stable laboratory populations of these two leafminers are cultured through standardized procedure in our laboratory, having a history of about 48 generations for L. huidobrensis and 160 generations for L. sativae. A large-scale population of more than 100 mating pairs is essential for supporting a stable population of L. sativae. There exists clear difference in morphology of the four developmental stages and in damage characters with larvae between these two species. L. huidobrensis has longer developmental periods, and lays fewer eggs, but has much longer period of oviposition than L. sativae. These differences are considered as the important reasons why L. huidobrensis is easier to culture than L. sativae in laboratory. Availability of their laboratory populations established foundations for future study on species acclimation, host selection, resistance screening and for other physiological and ecological studies.
