1982年雨季,印度卡纳塔邦境内第一次发现一种捕食性蝽象,鉴定为Microvelia atrolineata。这种食虫蝽象主要取食蝎稻虱的若虫。它的若虫和成虫经常出现在受害禾科四周的水面上,当褐稻虱的若虫和成虫掉下水面时,它就立即上前取食,有时纠集成群多至7、8只攻击1只褐稻虱。水稻乳熟期,每400平方厘米,常有10—12只这种食虫蝽象,因此虫能大量取食褐稻虱的1、2龄若虫,故对压低褐稻虱的虫口密度有明显的作用。
For the first time in the rainy season of 1982, a predatory stink bug was found in Indian state of Karnataka and was identified as Microvelia atrolineata. This insecticidid stinkbug infests nymphs that predate louse infestation. Its nymphs and adults often appear on the water surface of the damaged Wo family, when nymphal and nymphs of Nilaparvata lupus drop off the surface of the water, they immediately feed forward, sometimes gathering as many as 7, 8, attacking 1 brown Tick. Milk milky period, every 400 square centimeters, often 10-12 only bug insects such as insects, so insects can eat large quantities of brown planthopper 1, 2 instar nymphs, it is obvious to reduce the population density of brown planthopper Role.
