Oilseed rape (Brassica napus) has numerous insect pests, some of which are stem-miners. Currently, blue stem weevil (Ceutorhynchus sulcicollis) is not considered a pest of oilseed rape. In the present study, a total of 60 (30 untreated, 30 insecticide-treated) oilseed rape plants were dissected; and stem-mining larvae were collected, and subsequently allowed to pupate in soil. After pupation, all emerged adult weevils were identified as either blue stem weevil (C. sulcicollis) or cabbage stem weevil (Ceutorhynchus pallidactylus). We report that under favourable conditions C. sulcicollis was capable of reaching pest status, and was significantly more abundant than C. pallidactylus, indicating a critical need for future studies regarding C. sulcicollis.

油菜 ( Brassica napus ) 有许多害虫，其中一些是茎矿工。目前，蓝茎象鼻虫（Ceutorhynchus sulcicollis）不被认为是油菜害虫。在本研究中，共解剖了 60 株（30 株未经处理，30 株经杀虫剂处理）油菜植物；收集采茎幼虫，随后在土壤中化蛹。化蛹后，所有出现的成年象鼻虫都被鉴定为蓝茎象鼻虫（C. sulcicollis）或卷心菜茎象鼻虫（Ceutorhynchus pallidactylus）。我们报告说，在有利的条件下C。sulcicollis能够达到害虫状态，并且显着多于C. pallidactylus ，表明对C的未来研究的迫切需要。沟颈。
