荸荠白螟(Scirpophaga nivlca Fab.)俗称荸荠螟、白螟。在我国江苏、浙江、安徽、江西等省大多数县均有分布。幼虫为害荸荠、席草、甘蔗等植物。在本地区主要为害水生植物荸荠的地上部分(茎、叶)造成荸荠(食用球茎)减产。同时茎叶为害后,不能编织草帽等物品,失去利用价值。 本地区每年发生3—4代,以8月下旬至9月上旬的第三代幼虫为害最严重。因成虫有选择性产卵习性,凡长势好的田块,为害最严重,枯心苗多达60％以上。有明显的枯心塘(和水稻三化螟一样);也有虫伤 Water chestnut white borer (Scirpophaga nivlca Fab.) Commonly known as water chestnut borer, white borer. In our country Jiangsu, Zhejiang, Anhui, Jiangxi and other provinces are most of the distribution. Larvae harm water chestnuts, mat grass, sugar cane and other plants. Water chestnuts (edible bulbs) are cut in the aerial parts (stems, leaves) of the major aquatic plant water chestnuts in the region. At the same time stems and leaves harmful, can not knit straw hat and other items, loss of use value. 3-4 generations occur in the area each year, with the third generation larvae most severely affected in late August to early September. Because adults have selective spawning habits, where good growing plots, the most serious damage, as many as 60% of seedlings. There is obvious dead heart pond (and rice borer the same); also have insect damage
