摘要: 目的 探索高效氯氟氰菊酯微囊悬浮剂在绿篱上滞留喷洒对蚊虫的防制效果。方法 2015年8月13日启动试验,持续进行1个月,选择自然条件和蚊虫密度一致的对照区、试验区共2个区域进行研究。在试验区采用低容量喷雾对绿篱叶片(重点是叶片背面)进行滞留喷洒,并采用CO2诱蚊灯法对施药前后成蚊密度进行持续监测,用相对密度下降率(%)来评价防制效果。结果 对试验区绿篱进行滞留喷洒处理后,与对照区相比,处理后2周内蚊虫相对密度下降率均>80%,处理后第3、4周相对密度下降率均>70%。上述研究在同一地点于2017年8月中旬的重复结果与2015年研究结果基本保持一致。结论 基于对环境安全和蚊虫可持续控制的考虑,配合环境治理措施,在适宜的应用环境和条件下,采用合理的药剂和剂型规范地对绿篱进行滞留喷洒,对较高密度成蚊能持续发挥较好的控制效果。

Abstract: Objective To investigate the effect of residual spraying of lambda-cyhalothrin microcapsule suspension on hedgerow in preventing and controlling mosquitoes. Methods This test was initiated on August 13, 2015, with a duration of one month. Two areas (control area and test area) with similar natural conditions and mosquito density were studied. Residual spraying was implemented using low-volume spray on the leaves (especially the backside) of the hedgerow in the test area. The change in the density of adult mosquitoes after spraying was continuously monitored by the CO2 lamp trapping method. The prevention and control effect was evaluated by the decrease rate (%) of relative density. Results After residual spraying of the hedgerow in the test area, the relative density of mosquitoes showed a decrease rate of more than 80% within 2 weeks and a decrease rate of more than 70% at 3 and 4 weeks after treatment as compared with those in the control area (no insecticide treatment). The study above was repeated once in the same place in mid-August, 2017, with the obtained results basically consistent with those in 2015. Conclusion Taking account of environmental safety and sustainable control of mosquitoes, it can achieve a good control effect on relatively high-density adult mosquitoes by standardized residual spraying on hedgerow using proper insecticides and dosage forms under feasible application environments and conditions accompanied by environmental control measures.
