摘要:

  【摘要】 目的 通过药物处理蚊帐对蚊虫进行击倒实验,在北湾地区室内环境中通过药物处理蚊帐对蚊虫快速击倒效果进行研究。方法 研究中选用经BASF药物处理蚊帐、20次洗涤的BASF药物处理蚊帐、5 ml有效成分10%的奋斗呐处理的普通蚊帐(WHO推荐),普通军用蚊帐作为对照,在野外环境中用吸蚊器采集当地优势蚊种刺扰伊蚊分别放入4种处理蚊帐中,观察4种处理蚊帐对当地蚊虫的首数击倒、半数击倒、全数击倒时间,最后比较分析4种处理蚊帐对当地主要蚊种的快速击倒效果。结果 在对当地主要蚊种刺扰伊蚊的快速击倒效果上,经药物处理的BASF蚊帐>清洗20次药物处理的BASF蚊帐>WHO推荐的奋斗呐处理的蚊帐。3种处理蚊帐在7 min以内都能形成对蚊虫的首数击倒,3种蚊帐在首次击倒时间上差异无统计学意义(F=2.375, P=0.174), 在17 min内形成半数击倒,BASF药物处理蚊帐与奋斗呐处理蚊帐在时间上差异有统计学意义(P=0.036); BASF 2种处理蚊帐在27 min内可以全部击倒蚊虫, 奋斗呐处理的蚊帐则要54 min才能全部击倒蚊虫,BASF 2种处理蚊帐与奋斗呐处理蚊帐间差异均有统计学意义(P<0.001)。结论 经过药物处理的蚊帐比不经任何处理的普通蚊帐对蚊虫击倒效果要好,适当选择药物处理蚊帐可以为北湾边防部队提供有效的保护。

Abstract:

 【Abstract】 Objective To know the knockdown efficacy of mosquito?net treated by pesticides on mosquito in Beiwan. Methods The net treated by BASF® pesticide, the net treated by BASF® pesticide after washing twenty times and the net treated by FendonaTM recommended by WHO were used in treated area, and common military nets were selected in the control areas. Aedes vexans, the dominant species in Beiwan, was collected by mosquito aspirators and released into nets. The first knockdown time, medium knockdown time and total knockdown time were recorded, and then compare the knockdown time of 4 kinds of mosquito?net. Results For the knockdown efficacy to mosquito, the order was net treated by BASF® pesticide>net treated by BASF® pesticide after washing twenty times>net treated by FendonaTM recommended by WHO. The first knockdown time for three kinds of mosquito net  was  all  within 7 min, and there was no significant difference among them (F=2.375, P=0.174).  Medium knockdown time was 17 min, and there was significant difference between net treated by BASF® pesticide and  net treated by BASF® pesticide after washing twenty times (P=0.036). All the mosquito would be knocked down within 27 min for net treated by BASF® pesticide and net treated by BASF® pesticide after washing twenty times and 54 min for net treated by FendonaTM. There was significant difference among them (P<0.001). Conclusion The knockdown efficacy of net treated by pesticides could be better than non?treated net in Beiwan.
