摘要
竹直锥大象虫(Cyrtotrachelus longimanus Fabricius)又名长足弯颈象,是竹子的重要害虫,往往造成严重的经济损失。我们从它的钻蛀性和生活史中土栖时间长等生态特性考虑,应用昆虫病原线虫进行了防治试验。在室内筛选中,发现这种害虫对格氏线虫(Steinernema glaseri Steiner)(包括KG、NC52品系和采自广东省阳江市的中国品系85011等)十分敏感,感染死亡率达80%以上。在竹林现场防治试验中,每虫笋滴注2,000条感染期线虫,杀虫效果一般可达70%以上。试验表明,昆虫病原线虫对于竹直锥大象虫的防治,是具有应用前景的。
The bamboo weevil, Cyrtotrachelus longimanus is irnportant pest of the bamboo shoots in south china.The results of our work showed that the use of the entomopathogenic nematodes to treat injected shoots has got primary success. There are 24 strains or species of the genus Steinernema and Heterorhabditis were applied. Over 70% borer were killed by the injected nematodes of three strains of Steinernema, glaseri in field tests. It is likely to prove a available method for control of this pest.
