木蠹蛾（鞘翅目：天牛科）是一种次生木蠹，被认为能够传播引起松树萎蔫病（PWD）的木蠹蛾。这一事实表明，PWD有在欧洲蔓延的风险，因此迫切需要有效的工具来检测和监测线虫和传播该疾病的昆虫物种。最近报道的2 -十一烷基氧基- 1 -乙醇为它们。Sutormale产生的聚集信息素为该物种开发有效的诱捕剂提供了可能性。已知一些欧洲树皮甲虫信息素化合物和寄主挥发物经常吸引这种物种。此外，燃烧树木的烟雾挥发物可能在m中起作用。sutorhost位置。本研究在三个国家（西班牙、瑞典和奥地利）进行了为期3年的诱捕实验，旨在开发一种高效的信息素-凯罗蒙诱捕剂的有效形式。进行了支持性管理。天线电图响应。还研究了异温素和异温素。GC - EAG记录显示m。雄性和雌性对异丙酚和异丙二酚有明显的反应，雌性对2‐甲基‐3‐丁烯‐2‐醇也有反应。查尔斯格兰引起了汤姆的反应。sutorfemale天线。在田间试验中，益senol是对m的两性最具吸引力的激素。而异二烯醇、顺式马鞭酚和2 -甲基- 3 -丁烯- 2 -醇具有吸引力，而硫醇具有吸引力。当与信息素结合使用时，大多数树皮甲虫激素增加了两性的渔获量，而黄铜矿素完全无效。因此，ipsenol是最强的个体激素形式。素和单素最好与费洛蒙结合。在西班牙和奥地利测试的烟雾挥发性混合物没有引起反应，这表明这些化合物可能与该物种寻找宿主无关。
Monochamus sutor(Linnaeus) (Coleoptera: Cerambycidae) is a secondary wood borer that has been hypothesized as capable of transmittingBursaphelenchus xylophilus,the causal agent of pine wilt disease (PWD). This fact supposes a risk of spread of PWD over Europe and has created an urgent need for effective tools to detect and monitor both the nematode and the insect species that vectors it. Recent reporting of 2‐undecyloxy‐1‐ethanol as theM. sutormale‐produced aggregation pheromone has opened the possibility of developing an efficient lure for this species. It is known that some European bark beetle pheromone compounds and host volatiles kairomonally attract this species. Besides, smoke volatiles from burnt trees might play a role inM. sutorhost location. In this work, field trapping experiments during 3 years in three countries (Spain, Sweden and Austria), aimed to develop an efficient pheromone‐kairomone lure operative forM. sutormanagement were carried out. Electroantennographic responses byM. sutortoIpspheromones and to thePityogenes chalcographuspheromone chalcogran were also studied. GC‐EAG recording showed thatM. sutormales and females clearly responded to ipsenol and ipsdienol, and females also responded to 2‐methyl‐3‐buten‐2‐ol. Chalcogran elicited a response toM. sutorfemale antennae. In field tests, ipsenol was the most attractive kairomone to both sexes ofM. sutor, whereas ipsdienol, cis‐verbenol and 2‐methyl‐3‐buten‐2‐ol were attractive and chalcogran was unattractive. When combined with the pheromone, most bark beetle kairomones increased catches of both sexes although chalcogran was completely ineffective. Thus, ipsenol was the strongest individual kairomone forM. sutorand the best single kairomone to be combined with the pheromone. Smoke volatile blends tested in Spain and Austria did not elicit responses, suggesting that these compounds are likely not involved in host finding by this species.
