摘 要:
松材线虫（Bursaphelenchus xylophilus（Steiner et Buhrer）Nickle）引起的松萎蔫病是松树的一种毁灭性病害，该线虫原产于北美，借助于人类的贸易等活动，已于1982年扩散至我国并迅速蔓延。松材线虫需借助昆虫媒介才能完成寄主松树间扩散蔓延。松墨天牛（Monochamus alternatus Hope）是东亚松林内习见的蛀干害虫，是松材线虫最有效的传播媒介。有关该虫行为反应的研究，国内外虽有一些报道，但缺乏系统深入的研究。1986年以来，作者在研究松墨天牛综合防治技术过程中，陆续开展了成虫行为反应的系列研究。研究松墨天牛成虫的行为反应，对于深入探索该虫种群发展、松材线虫传播机制、灾害成因及其制定控制策略具有重要的科学意义。[第一段]

Abstract:
The results of the study showed that the optimum daily mean temperature that M. alternatus adult＇ s eclosion and leave host trees was 25 - 26 ℃. Monochamus alternatus adult carting Bursaphelenchus xylophilus, both the longevity and feeding numerical were lower than that of the non-carrier. The phototactic proportion of the population quantity of M. alternatus female and male adults was 1 ： 1.8. The population quantity proportion of M. alternatus femal and male adults flown to attractant was 1 ： 1.3. Under controlled condition, when M. alternatus adults 2 ♂ × 1 ♀ and 1 ♂ 1♀ reared respectively, for the former, the mean amount of egg deposited was 107.2, while the latter was 153.6. Of the two for non-pit quantity, the former was rather high or than the latter.[著者文摘]
