脐腹小蠹是新疆北部地区榆树树干的主要害虫 ,在奎屯一年发生 2～3代 ,以老熟幼虫在树皮内越冬。脐腹小蠹不断地重复侵害树势衰弱的植株 ,加快衰弱的速度 ,导致被害株迅速死亡。死亡不久砍伐的原木 ,最适於脐腹小蠹定居繁殖 ,是主要的虫源地。保证林木健康生长和消除虫源地是脐腹小蠹综合防治的基本环节。 Umbelorn beetle is the main pest of the elm tree trunk in the northern part of Xinjiang. It takes 2 to 3 generations a year in Kuitun to overwinter its mature larvae in the bark. The abdomen beetles continue to repeatedly infringe on plants with weak bonsai trees, speeding the rate of debilitation and causing the victim to die rapidly. The logs that died shortly after the harvest were most suitable for colonization and reproduction of Umbilicus, which is the main source of insects. To ensure the healthy growth of forest trees and to eliminate the source of insects is the basic part of comprehensive prevention and treatment of Beetles.
