摘要
柑橘木虱对常规杀虫剂的抗性不断上升,为减缓抗性的发展,更好地利用现有杀虫剂资源,对双甲脒和噻虫胺进行混配配方筛选。在盆栽实验中,进行不同配方对成虫的速效性和持效性实验,接着通过田间试验检测防效。在6个配方中,筛选出3个具有速效性的配方,20%双甲脒EC和48%噻虫胺SC的配比按有效成分计算分别为:134.00 mg/kg:80.40 mg/kg,134.00 mg/kg:60.00 mg/kg和100.00 mg/kg:60.00 mg/kg,这些配方药后3 d矫正死亡率分别100.00%、96.51%和96.37%。田间药效试验结果显示,前两个配方的3 d防效均为100.00%,10 d防效为96.91%和96.45%,表明这两个配方具有速效性。本研究结果可为柑橘木虱的化学防治提供新策略。
With the increasing resistance of Diaphorina citri Kuwayama to conventional insecticides,complex formulations of amitraz and clothianidin were screened to slow down the development of the resistance and take better use of existing pesticide resources. In pot experiments, different quick and lasting-effect formulation against adults was tested. The control efficacy of the formulation was tested by field experiments.Among 6 formulations, 3 of them had quick-effect. The ratio of 20% amitraz EC and 48% clothianidin SC were134.00 vs 80.40 mg/kg, 134.00 vs 60.00 mg/kg and 100.00 vs 60.00 mg/kg. The corrected mortality rate of 3rd day after treatment were 100.00%, 96.51% and 96.37%, respectively. In field trials, the control effects of 134.00 vs80.40 and 134.00 vs 60.00 on 3rd day were 100%, and they were 96.91% and 96.45% on 10 th day. The results of this study provided a new strategy for chemical control over D. citri Kuwayama.
