各种害虫的生活习性和抗寒能力不同,越冬的方式与藏身的地方也不一样。有的以幼虫、蛹的形态越冬,也有的以卵或成虫度过寒冬。玉米螟以幼虫在玉米棒、玉米秆和高粱秆里越冬;粟灰螟以幼虫在谷茬内越冬;粟穗螟则以幼虫在粮仓及场边的草垛下潜伏越冬;二化螟以老熟幼虫在稻茬和稻草内越冬,蛴螬和象(虫甲)的幼虫却在土壤中越冬。蝼蛄、金针虫和地老虎一般在地下15~25厘米处做土室过冬;棉铃虫以蛹在辣椒、番茄等地里越冬;曲条跳(虫甲)以成虫在落叶、枯草中潜伏越冬。果树上的许多害虫,一般就躲藏在果树的裂缝、树梢、落叶落果里和周围杂草上过冬。也有的害虫在土隙石缝、屋角墙缝和农作物的种子里越冬。
The habits and cold tolerance of various pests are different, and the ways of overwintering are different from those of hiding place. Some larvae and pupae overwintering, and some with eggs or adults through the winter. Corn borer larvae overwinter in corn cobs, corn stalks and sorghum stalks; corn borer larva wintering in stubble; corn ear borer larva in the silos and on the side of the haystack under the winter lurking; Mature larvae overwinter in rice stubble and straw, while larvae of slugs and elephants (Arborvitae) winter in the soil. Scabies, pinworms and tigers usually make earth-mounds in the ground 15 to 25 centimeters over the winter; the cotton bollworm pupae in the peppers, tomatoes and other places in the winter; song hop (insect) to adults in the leaves, subtilis lurking overwintering. Many pests on fruit trees are generally hiding in cracks in fruit trees, treetops, deciduous fruit and the surrounding weeds on winter. Some pests also winters in crevices, corner joints and crops.
