The bark weevilPissodes nemorensis, a pest of pines and exotic cedars in the southeastern United States, utilizes a male-produced aggregation pheromone. The presumed pheromone components, grandisol (cis-2-isopropenyl-1-methylcyclobutaneethanol) and its corresponding aldehyde, grandisal, were isolated from extracts of male volatiles and male hindguts. A field test in northern Florida showed that the combination of grandisol, grandisal, and slash pine (Pinus elliottii) bolts acted synergistically to attract large numbers of male and femaleP. nemorensis. These components deployed in various paired combinations were not as attractive as the tripartite mixture. There was no evidence that flying weevils were attracted to unbaited pine bolts. The aggregation pheromone forP. nemorensis appears to be similar to that of a parapatric sibling species,P. approximatus.
树皮象鼻虫 Pissodes nemorensis 是美国东南部松树和外来雪松的害虫，它利用一种雄性产生的聚集信息素。从雄性挥发物和雄性后肠提取物中分离出了假定的信息素成分大根香叶醇（顺式-2-异丙烯基-1-甲基环丁烷乙醇）及其相应的醛，大根香叶醛。在佛罗里达州北部的田间试验表明，大根香叶醇、大根香叶醛和湿地松（Pinus elliottii）原木的组合协同作用，吸引了大量的雄性和雌性 P. nemorensis。这些以各种配对组合部署的成分不如三元混合物具有吸引力。没有证据表明飞行象鼻虫会被未诱饵的松树原木吸引。P. nemorensis 的聚集信息素似乎与近缘种 P. approximatus 的信息素相似。
