摘要/Abstract

摘要： 以稻纵卷叶螟为研究对象，按不同配方配制了6种人工饲料分别用来饲养稻纵卷叶螟，以筛选出适合饲养稻纵卷叶螟的人工饲料。结果表明，在温度为24~26 ℃，相对湿度大于80%，光照条件大于14 h的条件下，其中饲料D、E、F饲养稻纵卷叶螟二龄幼虫只能完成二龄发育，少数幼虫存活到三龄或三龄以上；饲料C饲养稻纵卷叶螟二龄幼虫也只能完成三龄发育；而饲料A和B饲养的稻纵卷叶螟二龄幼虫能完成整个世代发育，存活率分别为26.17%和36.40%，接近对照组新鲜水稻叶饲养的存活率36.67%，且蛹质量和新鲜水稻叶饲养的幼虫没有显著差异，但与对照相比，幼虫历期延长4~6 d、化蛹率下降8%~9%、羽化率下降11%~12%。

Abstract:

Rice leaffolder (Cnaphalocrocis medinalis Guenee) is one of destructive and widespread insect pest throughout the rice growing regions from the tropics to temperate zone. The present article deals with the artificial diet for Cnaphalocrocis medinalis Guenee. Under the conditions of 24~26 ℃, RH 80% and 14(L):10(D), most of the second instar larvae reared on the diet D, E, F could not survive to the third instar; none of the second instar larvae reared on the diet C could develop to the 4th instar; if the second instar larvae were reared on the diet A, B, they could develop to adults, and their survival and pupa weight were similar to the controls, but the larvae developmental period, pupation and eclosion rate were lower than the control's.

Key words: Cnaphalocrocis medinalis Guenee, artificial diet, survival rate, pupation rate, eclosion rate
