不同小蠹类与天牛类引诱剂联用对蛀干甲虫的林间诱捕效果

松墨天牛Monochamus alternatus Hope是传播松材线虫病的主要媒介，引诱剂是抑制松墨天牛种群数量的无公害调控有效方式之一。本研究通过在中国浙江富阳的林间试验测定了6种小蠹类引诱剂与1种天牛引诱剂不同组合联用对松墨天牛成虫以及其他蛀干害虫的诱捕效果。结果表明： 横坑切梢小蠹Tomicus minor引诱剂3-carene-10-ol、云杉八齿小蠹Ips typographus引诱剂2-methyl-3-buten-2-ol、欧洲榆小蠹Scolytus multistriatus引诱剂4-methyl-3-heptanol和纵坑切梢小蠹T. piniperda引诱剂verbenol分别与松墨天牛引诱剂联用后，对松墨天牛的引诱效果无显著性差异(P<0.05)。西部松大小蠹Dendroctonus brevicomis 引诱剂exo-brevicomin或黄杉大小蠹D. pseudotsugae引诱剂1-methylcyclohex-2-en-l-ol与松墨天牛引诱剂联用后对松墨天牛的诱捕效果有减弱的趋势。另外，与单独使用中国天牛引诱剂相比，小蠹类引诱剂与其联用后在诱捕其他蛀干害虫的种类和个体数量上均有所减少。

Field efficacy of combinations of attractants for bark beetles and longicorn beetles in trapping wood-boring beetles

 Monochamus alternatus Hope is the primary vector for spreading pine wilt disease. Use of attractants in the control of M. alternatus population is effective and pollution-free. In this study, the field test was conducted to evaluate the attractiveness of M. alternatus attractant combined with six kinds of bark beetle attractants to M. alternatus adults. The results showed that there was no significant difference among the combinations of each of bark beetle attractants for Tomicus minor Hartig (3-carene-10-ol), Ips typographus Linnaeus (2-methyl-3-buten-2-ol), Scolytus multistriatus Marsham (4-methyl-3-eptanol), and T. piniperda Linnaeus (verbenol) with M. alternatus attractant (P<0.05). The combinations of attractants for either Dendroctonus brevicomis LeConte (exo-brevicomin) or D. pseudotsugae (1-methylcyclohex-2-en-l-ol) with M. alternatus attractant were less attractive to M. alternatus. Compared with M. alternatus attractant used only, the combination of either D. brevicomis or D. pseudotsugae with M. alternatus attractant was also less attractive as indicated by the species and number of wood-boring beetle individuals captured.
