刺桐姬小蜂Quadrastichus erythrinaeKim是一种新入侵的有害生物,仅危害刺桐属植物Erythrina spp.,繁殖能力强,扩散速度快。为了有效控制刺桐姬小蜂的危害,本研究通过施药方法、药剂浓度试验对不用作用类型的9种农药进行筛选,结果表明,使用树干注射施药防治刺桐姬小蜂效果明显高于包杆施药和喷雾;混剂25%吡虫啉.丁硫克百威防治效果较高,10d后防治效果可以达到95%以上,其它药剂防治效果由高到低依次为:20%丁硫克百威、30%敌敌畏.氧化乐果、8%吡虫啉.啶虫脒、31%氟虫腈.三唑磷、20%氧化乐果、5%吡虫啉、5.1%吡虫啉.阿维菌素、10%敌敌畏。
Quadrastichus erythrinae Kim is a newly invaded pest that damages only the Erythrina spp., Which is highly fertile and diffuses rapidly. In order to effectively control the harm of the hedgehog wasps, nine kinds of pesticides of non-use type were screened by the method of application and the test of the drug concentration. The results showed that the effect of using the trunk injection to prevent and cure the hedgehog was significantly higher Including spraying pesticides and spray spraying. The control effect of 25% imidacloprid and metsulfuron-methyl is higher, and the control effect after 10 days can reach more than 95%. The control effects of other agents are as follows: 20% Oxymeto, 8% Imidacloprid, Acetamiprid, 31% Fipronil, Triazophos, 20% Omethoate, 5% Imidacloprid, 5.1% Imidacloprid, Abamectin, 10% .
