小麦沟牙甲(Helophurus auriculatus Sharp)是我县近几年发生的一种毁灭性地下害虫,喜潮湿,主要发生在稻麦两熟地区的麦田。1984年以来,由于稻田排水不畅,低洼田面积扩大,田间杂草较多有利于此虫产卵、繁殖,危害日趋严重。全县发生面积6万余亩,分布于23个乡镇,一般造成缺苗20％～40％,严重田块达80％以上。

Helophurus auriculatus Sharp is a destructive underground pest that occurred in our county in recent years. It likes moisture and mainly occurs in the fields of wheat and wheat. Since 1984, due to the poor drainage of paddy fields and the expansion of the area of ​​low-lying fields, more weeds in the fields are good for spawning and breeding of the insects and the harm is becoming more and more serious. The county has an area of ​​more than 6 acres, located in 23 townships, the general lack of seedlings caused 20% to 40%, more than 80% of the serious field.
