| 摘 要： | 开展了静电喷雾与非静电喷雾48%噻虫啉悬浮剂和2%噻虫啉微胶囊悬浮剂防治马尾松毛虫Dendrolimus punctatus(Walker)和蜀柏毒蛾Parocneria orienta Chao林间试验。试验结果表明:使用相同浓度药液,静电喷雾的防治效果明显优于非静电喷雾的防治效果,药液浓度越低,增效幅度越大;静电喷雾低浓度药液与非静电喷雾高浓度药液能获得同样防治效果,可节省农药30%以上;48%噻虫啉悬浮剂4 000倍液和2%噻虫啉微胶囊悬浮剂2 000倍液可作为静电喷雾防治马尾松毛虫3～4龄幼虫和蜀柏毒蛾4～5龄幼虫的适宜药液浓度。 |

| Abstract: | Experiments were made in the forest with Thiacloprid 48% SC and Thiacloprid 2% CS against Dendrolimus punctatus and Parocneria orienta by means of electrostatic and non-electrostatic spraying.The results showed that the field control effect of electrostatic spraying was significantly better than that of non-electrostatic spraying at the same concentration.The lower the pesticide concentration,the greater the synergistic effect.Electrostatic spraying with low pesticide concentration could obtain the same control effect as non-electrostatic spraying with high pesticide concentration and save more than 30% of the pesticides.Thiacloprid 48% SC 4 000 times and Thiacloprid 2% CS 2 000 times could be used as the suitable concentration in electrostatic spraying against the 3rd and 4th instar larvae of Dendrolimus punctatus and the 4th and 5th instar larvae of Parocneria orienta. |
