木橑尺蠖 Culcula panterinaria Bremer et Grey 是一种杂食性的尺蛾类害虫,在浙江杭州以蛹在茶树根际附近土中越冬,年发生2—3代。气温和相对湿度是影响木橑尺蠖生长、发育的主要环境条件。风可帮助初孵幼虫扩散,大暴雨可使低龄幼虫致死,土壤质地则影响入土化蛹深度。主要天敌是木橑尺蠖核型多角体病毒(NPV)。防治宜采用灯光诱杀、人工捕捉、保护利用天敌和化学农药综合措施。化学农药以3.12ppm 溴氰菊酯、12.5ppm 氯氰菊酯、20ppm 杀灭菊酯、40ppm 多虫畏、250ppm 喹硫磷及250ppm 灭幼脲Ⅲ效果较好。
Culcula panterinaria Bremer et Gray is a omnivorous moth pest that pupae in Hangzhou, Zhejiang Province, wintering in the soil near the rhizosphere of tea trees, occurring 2-3 generations annually. Temperature and relative humidity are the main environmental conditions that affect the growth and development of the mullet. Wind can help the proliferation of newly hatched larvae, heavy rain can kill young larvae, soil texture will affect the depth of the soil into the pupation. The main natural enemy is Scleroderma nuclear polyhedrosis virus (NPV). Prevention and control should use light trapping and killing, artificial capture, protection and utilization of natural enemies and chemical pesticides comprehensive measures. The chemical pesticides with 3.12ppm deltamethrin, 12.5ppm cypermethrin, 20ppm fenvalerate, 40ppm dichlorvos, 250ppm quetiapine and 250ppm diflubenzuron Ⅲ better.
