为害荔枝树皮的新害虫荔枝巢蛾Comoritis albicapilla Moriuti在广东1年发生1代,由于幼虫藏匿于自身吐丝粘连粪粒组成的双层网下,使农药防治困难。作者以昆虫病原线虫为主,对比使用化学农药,寻求对该虫有效的防治方法。结果表明,荔枝巢蛾幼虫、蛹对昆虫病原线虫4个种的5个品系十分敏感,其感染率与病原线虫的剂量成正相关:Y=2.737+1.264X,LD_(50)=6.165 IJ/虫。但是,大田防效很不稳定,在同一剂量下,其防效可从14.2％～92.1％。研究表明,树皮的湿度是影响线虫存活和防治效果的最重要因素,春天雨季喷雾昆虫病原线虫防治荔枝巢蛾效果很好。
New pests that harm the litchi bark Comoritis albicapilla Moriuti occurs in Guangdong for one year and lives in the second generation because of larvae hiding in the double layer network formed by self-sticking shit and pellets, making pesticide difficult to control. The author of the main entomopathogenic nematodes, compared to the use of chemical pesticides, to seek effective control of the worm. The results showed that larvae and pupae of the larvae nest moth were very sensitive to five strains of four species of entomopathogenic nematodes. The infection rate was positively correlated with the dose of pathogenic nematodes: Y = 2.737 + 1.264X, LD50 = 6.165 IJ / . However, the field control effect is very unstable, with the same dose, the control effect can be from 14.2% to 92.1%. Studies have shown that the bark humidity is the most important factor affecting the survival and control effects of nematodes, the spring rainy season spray nematodes nematode control Lyme worms good results.
