苯酰基脲类杀虫剂防治苹果金纹细蛾研究

Experiments of Benzoylphenyl Urea Insecticides in Asiatic Apple Leaf-miner Control

作者于1996年进行了苯酰基脲类杀虫剂防治金纹细蛾的试验研究,灭幼脲、除虫脲、杀铃脲、氟虫脲对金纹细蛾有良好的防治效果。灭幼脲1 000～2 000倍、除虫脲 3 000倍、杀铃脲和氟虫脲各 5 000倍在防治后1个月内对叶片的保护作用均能达90％以上。从药效和成本综合考虑,生产上首选药剂为25％灭幼脲悬浮剂,推荐使用浓度为2 000～3 000倍。

Experiments of benzoylphenyl urea insecticides in controlling asiatic apple leaf-miner (Lithocolletis ringonieiia)on apple trees were carried out in summer of 1996. Mieyouniao, di-flubenzuron, triflubenzuron and flufenoxuron are highly effective to control larvae of the leaf-miner. The effectiveness of the leaf protecion could be over 90 % within 30 days after spraying 0. 5‰- 1‰ of Mieyouniao, 0. 33‰ of diflubenzuron, 0. 2‰ of triflubenzuron and flufenoxuron. In terms of effective and economic consideration, the best choice for production use is 25% suspension mieyouniao. Recommended application concentration is 2‰-3‰.
