大螟Sesamia inferens(Walker)是杂食性害虫,在我国南方稻区常为害水稻、玉米、高粱、禾筍、黄蔴、甘蔗等作物,由于暴食量大并常转株加重为害,形成枯心死苗,而且,近年来有发展上升趋势,尤杂交稻的发展对其发生更为有利,因此,大螟的测报和防治已显得甚为需要。大螟测报方法过去防治用诱测灯,但由于大螟趋光性弱,扑灯虫数少,资料残缺,规律不明,对测报和防治是有困难的。近年来,各种引诱剂的使用,已成为害虫管理中有魅力的工具。
Sesamia inferens (Walker) is a omnivorous pest. It is often damaging to rice, corn, sorghum, grass shoots, jute, sugarcane and other crops in the southern rice area in China. In recent years, there has been an upward trend in development. In particular, the development of cross hybrid rice is more favorable to its occurrence. Therefore, it is quite necessary to measure and control Sesamia inferens. Sesamia internode method used to control the past with the detection of light, but due to the weak phototacticity of Sesamia internodes, small number of flutter insects, incomplete data, the law is unknown, the report and prevention is difficult. In recent years, the use of various attractants has become an attractive tool in pest management.
