Landing counts made in a residential area in San Juan, Puerto Rico during the 5-year period, 1980-84 indicated that malathion ULV applied by LECO Fog Generators was not effective against Aedes aegypti. Of 25 applications only 6 resulted in a decrease on the first day after treatment and only one remained much less than the pretreatment count on the second and third days after treatment. Daily, the number of mosquitoes landing for a 5-minute period at each of 2 stations was recorded. An ideal year created by averaging the monthly data suggested that the seasonal variation of mosquitoes was inverse to that of reported dengue incidence.
1980年至1984年这5年期间，在波多黎各圣胡安的一个居民区进行的着陆计数表明，使用LECO烟雾发生器进行的马拉硫磷超低容量喷雾对埃及伊蚊无效。在25次喷雾中，只有6次在处理后的第一天导致蚊虫数量减少，只有一次在处理后的第二天和第三天仍远低于处理前的计数。每天记录两个站点中每个站点5分钟内着陆的蚊子数量。通过对月度数据进行平均得出的理想年份表明，蚊子的季节性变化与报告的登革热发病率的变化相反。
