小地老虎小地老虎Agrotisypsilon夜蛾科昆虫的一种。农作物的大害虫。分布于世界各地。中国各省(区)均有分布,其中以沿海、沿湖、沿河以及低洼内涝、土壤湿润而多杂草的旱粮区和粮棉间种地区发生最重,在其他旱作区、蔬菜区也有不同程度的危害。成虫翅展42~52毫米;雄蛾触角双栉形;前翅暗褐色,环纹、肾纹黑边,肾纹外有一黑色楔形纹,亚端线中段内侧有3个楔形黑纹;后翅灰白色。幼虫黄褐或暗褐色,体表粗糙,臀板有黑点。蛹红褐或暗褐色。年发生代数因地区而异。第一代幼虫危害重。食性杂,玉米、高粱、棉花、烟草、麻类、马铃薯、蔬菜等受害最重。成虫白天隐藏在阴暗处,夜间活动,对糖蜜和黑光灯趋性强。小地老虎卵多散产,喜产在小苗上。幼虫1~2龄取食心叶,3龄后扩散,白天潜伏根际,夜间活动,常切断嫩茎或将断苗拖至穴中。
