| 用啶虫脒等7种杀虫剂和其混剂对菜心种子包衣处理后，对种子安全性及保护作用进行评价，筛选适合菜心种子包衣防治黄曲条跳甲的杀虫剂。结果表明，各处理对菜心幼苗株高和株鲜重无显著影响，但对种子发芽势、发芽率、出苗率和受害指数方面的影响存在差异。苏云金杆菌（Bt）和乙基多杀菌素能提高种子发芽势、发芽率和出苗率，能显著降低菜心受害指数；啶虫脒、氟虫腈、虫螨腈和唑虫酰胺4种药剂相比，啶虫脒能显著降低菜心受害指数，氟虫腈次之，4.0 g/200 g处理剂量能显著降低菜心受害指数；虫螨腈和唑虫酰胺降低受害指数作用不显著；但啶虫脒3.0 g/200 g和4.0 g/200 g处理剂量对种子发芽势、发芽率和出苗率均有显著降低作用。氯氰菊酯与不同剂量啶虫脒、虫螨腈和氟虫腈混配后进行种子包衣处理，对种子安全性均较单剂差，前期均能显著降低种子发芽势。含有不同剂量啶虫脒的混剂与啶虫脒单剂具相似规律。总体而言，单剂Bt综合效果最优，啶虫脒、乙基多杀菌素、氟虫腈次之，虫螨腈和唑虫酰胺较差；混剂安全性较单剂差，但保护作用相对优于单剂。 |

| To screen the feasibility of flowering cabbage seed dressing with common used insecticides against striped flea beetle (Phyllotreta striolata),seven insecticides were applied to evaluate protective effect and safety assessment in present study. The results showed that under different treatments, all insecticides had different influence on seeds germination potential, germination rate and emergence rate except plant height and weight. Bt and spinetoram could promoted seeds germination potential, germination rate and emergence rate, and could reduce leaf injury index significantly effectively. Among acetamiprid, fipronil, chlorfenapyr and tolfenpyrad, acetamiprid could reduce leaf injury index significantly, but 3.0 g/200 g and 4.0 g/200 g treatment dose could significantly reduce seeds germination potential, germination rate and emergence rate; followed by fipronil, safety assessment was good and 4.0 g/200 gdose could significantly reduce the leaf injury index; safety assessment of chlorfenapyr and tolfenpyrad was also good, but there was no distinguishable difference in reducing leaf injury index. As flowering cabbage seed treated with mixed insecticides (cypermethrin+acetamiprid, fipronil and chlorfenapyr respectively), low seeds germination potential was investigated, and safety assessment was not as good as above single insecticides. The mixture of cypermethrin and acetamiprid showed a similar situation with single acetamiprid agent. Overall, Bt is the best, followed by acetamiprid, spinetoram and fipronil, but chlorfenapyr and tolfenpyrad were relatively worse. The safety of mixed insecticides was worse than that of the single insecticide, but the protective effect is relatively better. |
