甜菜象虫是辽宁省甜菜苗期生产上的重要害虫之一。辽西山地及辽河平原大部分地区适合藜科、苋科和蓼科植物的生长,其中有许多种类为象虫尤其是短喙象亚科(Br-achyderinae)和方喙象亚科(Cleoninae)的寄主植物。当甜菜幼苗出土后,这些象虫从野生寄主和去年甜菜地迁到本年甜菜地,咬食甜菜子叶和幼嫩的真叶,发生严重地块,造成田间缺苗断垄,需要毁种或补种。 Asteraceae is one of the most important pests in the seedling stage of beet in Liaoning Province. Most of the western Liaoning and the Liaohe Plain are suitable for the growth of the Chenopodiaceae, Amaranthus, and Polygonaceae species, many of which are elephants, particularly the Br-achyderinae and Cleoninae Host plant. After the beet seedlings were unearthed, these elephants moved from the wild host and last year’s beet to the beet in this year, biting beet leaves and tender young leaves, causing serious land blockages that caused the lack of seedlings to break the ridge, replant.
