不同浓度的3种药剂对黑竹缘蝽的防治效果研究

为探索黑竹缘蝽的无公害防治的方法，于2013年在福建省沙县选用1%苦参碱可溶性液剂（喷烟型）、12%烟碱·苦参碱乳油和18%阿维菌素乳油进行黑竹缘成虫和若虫的防治试验。结果表明，采用喷烟技术施放苦参碱类和阿维菌素乳油，用药后3d对防治黑竹缘蝽成虫和若虫的防治效果均可达80%以上。其中2种苦参碱类药剂防治中最佳使用量为1∶9，18%阿维菌素乳油最佳药剂用量为1∶40。

Preventive Effect of Different Concentrations of Three Kinds of Agents on Notobitus meleagris

To explore the pollution-free prevention method and control of Notobitus meleagris,1% matrine SL （smoke type）,1 .2% matrine-nicotine missible oil,and 1 .8% Avermectin missible oil were selected to test the preventive effect on control of the nymph and adult of N.meleagris at Shaxian County,Fujiang province in 2003 . The result showed that,after 3 d of spray matrine and Avermectin missible oil by smoke spray technology,the pre-ventive effect on nymph and adult was more than 80%.In which,the optimum agent dosage for two kinds of ma-trines was 1∶9 ,while 1∶40 was the best dosage for Avermectin missible oil.
