摘　　要：4 病原线虫及其应用 4．1线虫的研究概况 昆虫病原线虫（Entomopathogenic nematodes）属线形动物门，线虫纲的一类小型多细胞生物，其形态简单，种类繁多。它可寄生于昆虫体内，所以义称嗜虫线虫。嗜虫线虫以感染期线虫（Infective Juveniles，IJS）侵入健康幼虫、蛹、成虫体腔内，并杀死其昆虫个体。有些线虫侵染的性状类似寄生蜂的寄生；The management of underground pests in sugarcane has been relying on high toxic, high residual pesticides for a long time. The problems such as resistance, re-rampancy, residue and environmental pollution caused by it rendered considerable public concerns. It is an urgent call to develop a safer and more effective way of pest management. This paper reviewed the history, current situation, and reference value of the application of microorganism, nematode, insect enemy for biological control of sugarcane underground pests. The prospect of biological control was also discussed in this paper.
