| 摘 要： | 油菜茎象甲田间防治试验表明：５０％氧化乐果乳剂１０００倍液和２．５％溴氢菊酯乳剂４０００倍液喷雾对成虫的防治效果较好。春季始盛期喷药优于秋季。氧化乐果羊毛脂、久效磷羊毛脂和氧化乐果聚乙烯醇涂茎剂防治幼虫的效果较好。化学防治应以春季成虫出土始盛期药剂喷雾为主，辅以幼虫初期涂茎剂防治。

| Abstract: | The results of field experiment showed that omethoate (500ppm) anddeltamethrin (6.2ppm) gave good control against adults of rapeseed stem veevil(Ceutorrhynchus asper Roel.). The effectiveness of pestcide-spraying in initial stage of adultappearance in spring was higher than that in autumn. Smearing stem of rapeseed plant withmixtures of omethoate and wool grease and of monocrotophos and wool grease achieved higheffectiveness against larva. It was recommended that rapeseed stem veevil can usually becontrolled by a single spray in the early stage of adult appearance in the spring and bysupplementory application with stem-smearing treatment in the early larva stage. |
