摘  要:
脐腹小蠹Scolytus schevy(?)i Seme. 是克拉玛依地区榆树的主要害虫,研究表明该虫在克市一年发生两代,以老熟幼虫越冬,雌虫产卵46—75粒。幼虫在韧皮部和木质部之问取食,造成植株输导组织破坏,营养及水分的运输受阻。林区气候干燥、郁闭度低、树势差,脐腹小蠹发生严重。室内涂干灭虫试验表明,40%久效磷,3%呋喃丹+柴油、六六六粉+柴油灭虫效果很好。

摘  要:
The elm bark beetle, Scolytus schevyrewi Seine. is one of the most injurious insect pest of elm tree in Karamay region. Results from this report shows that the elm bark beetle appears in two generations per year on elm tree and the winter is passed in last instar larva in Karamay. The female lays 46—75 eggs. The larva feed on elm tree between the wood and the inner bark causing the damage of transporting tissue of the bark and impeding the transport of water and nutrition matter within elm trees when forestry is in dry weather, low canopy density and the trees are of poor growth. The laboratory experiment makes known that it is very effective by smearing the elm trees with 40% monocrotophous (EC), 3% carbofurran (granule) plus diesel oil and BHC(dust) plus diesel oil.
