目的 利用绿篱技术人工模拟现场，研究不同杀虫剂的灭蚊效果及滞留效果。方法 应用绿篱技术分别将2.5%高效氯氟氰菊酯微囊悬浮剂（大灭）、10%顺式氯氰菊酯（奋斗呐）和10.4%氯菊-烯丙菊水乳剂（列喜镇）喷淋鸭脚木，移入户外帐篷中，每帐放入雌性白纹伊蚊30只，24 h后放入1只小白鼠和4个诱蚊诱卵器，3 d后收集诱蚊诱卵器，观察并记录蚊虫存活数。结果 2.5%高效氯氟氰菊酯微囊悬浮剂可保持滞留灭蚊效果达21周以上，10%顺式氯氰菊酯可保持9周；10.4%氯菊-烯丙菊水乳剂无明显的滞留效果，蚊虫周最大存活数分别为4、15、21只，中位存活数分别为1、5、7只。结论 2.5%高效氯氟氰菊酯微囊悬浮剂和10%顺式氯氰菊酯在绿篱技术药物喷洒灭蚊中均具有良好的滞留效果，前者滞留效果更佳。

Objective To study the efficacy for mosquito control and residual effect of different pesticides by artificial simulation as barrier spray on vegetation. Methods Using insecticidal barrier spray on vegetation technology, Scheffleraoctophylla were sprayed separately by 2.5% effective chloric fluorine with ester millirod suspending agent (Demand), 10% alpha-cypermethrin (Fendona) and 10.4% chlorine chrysanthemum-allyl chrysanthemum water emulsion (alpha-cypermethrin). Then they were moved to an outdoor tent. A total of 30 female Aedes albopictus were put into every tent weekly. One rat and four mosquito oviposition device were introduced into every tent after 24 h, then collected mosquito eggs after 3 d, and recorded survived mosquitoes. Results 2.5% effective chloric fluorine with ester millirod suspending agent remained effective for more than 21 weeks, 10% alpha-cypermethrin for 9 weeks, and 10.4% chlorine chrysanthemum-allyl chrysanthemum water emulsion had no residual effect. The maximum of weekly counts for survivors was 4, 15 and 21 respectively. The median was 1, 5 and 7. Conclusion Both 2.5% effective chloric fluorine with ester millirod suspending agent and 10% alpha-cypermethrin have good mosquito killing and residual effect by using insecticidal barrier spray on vegetation, 2.5% effective chloric fluorine with ester millirod even better.
