水生捕食性昆虫小划蝽（Micronectaguadriseta），在鱼类养殖业中能侵害鱼苗、经观察它也捕食蚊幼虫，且捕食速度较剑水蚤快，同样的水体中，控制白纹伊蚊幼虫的效果和使用的投入量比剑水蚤类要好、少。在生物防制中，作为蚊虫的天敌之一，是一种值得保护和开发的资源。

Micronecta quadriseta is one of destructive insect in freshwater fish-farming.By observation it is to catch and feed on larva of Ade albopictus,too,Its speed of catching them is farster than Mesocyclops sp.as volume as in water,Its controlling efficiency is better and its using expenditures are less than latter with help of Micronecta quadriseta Lundblad under biocontrol of mosquitoes it is worth protecting and exploiting natural resources as a heavenly enemy of mosquitoes.
