灭幼脲是七十年代出现人工合成的一种昆虫几丁质合成酶抑制剂,属苯酰苯基脲类衍生物.它的主要作用是通过胃毒或触杀抑制昆虫表皮的几丁质合成,使变态受阻而丧失生命力.具有低毒、低残留、无污染,对人畜安全,使用方便等优点.是一种较理想的选择性杀虫剂.笔者于1986年4～6月对马尾松毛虫卵、幼虫及松大蚜的生物活性和杀虫效果进行了试验,现将结果整理报导如下:
Chlorbenzuron is an insect chitin synthase inhibitor synthesized in the seventies and belongs to the benzoylphenyl urea derivatives. Its main function is to inhibit the insect chitin synthesis through stomach poisoning or contact toxicity , So that perverted obstruction and loss of vitality. Has low toxicity, low residue, non-polluting, safe for humans and animals, easy to use and so on. Is an ideal selective insecticides.
