| 摘 要： | 选用8种药剂对观赏草坪斜纹夜蛾进行化学防治研究,并运用方差分析和新复极差(LSR)测验对试验数据进行分析。结果表明:生物农药BT及新型农药克蛾宝对该害虫有较为理想的防治效果,氧化乐果对该害虫有较好的防治效果。在虫口基数不大时可选用BT进行防治,在虫口基数大或高龄幼虫较多时应选用克蛾宝、氧化乐果进行防治,并正确进行药剂的交替使用,以延缓其产生抗药性。

| Abstract: | In this study, we compared the prevention and cure effects of eight kinds of pesticide on the prodenia litura in ornamental lawn by using the analysis of variance (ANOVA) and LSR method. The results showed that the pesticide BT and the new-developed pesticide KeEBao were effective, and omethoate was effective as well. If the cardinal number of insect was small, BT was recommended. When the cardinal number of insect was big or elderly larvae were the major, KeEBaao and omethoate were recommended. Meanwhile, alternate use of pesticide was Very important, which could delay the anti-drag probability. |
