We determined the site of pheromone production tissues and a partial route for the biosynthesis of the sex pheromone in Hedypathes betulinus (Coleoptera: Cerambycidae: Lamiinae), Brazil's main green maté pest. Pheromone was found predominantly in the prothorax of males, suggesting that this is the region of production of pheromones in this insect. Scanning electron microscopy revealed small pores that may be associated with pheromone release in males; these pores also were observed in females. A deuterium-labeled putative precursor (geranyl acetone-D5) of the sex pheromone of H. betulinus was synthesized. When applied to the prothorax of males, label from the precursor was incorporated into the pheromone components, confirming that pheromone production occurs in the prothorax and that the pheromone components are biosynthesized from geranyl acetone.
我们确定了巴西主要的绿色马黛虫（Hedypathes betulinus）（鞘翅目：天牛科：沟胫天牛亚科）产生信息素的组织部位和部分生物合成性信息素的途径。信息素主要存在于雄性的前胸，这表明前胸是该昆虫产生信息素的区域。扫描电子显微镜显示出可能与雄性信息素释放有关的小毛孔；这些毛孔在雌性中也有观察到。合成了巴西主要的绿色马黛虫性信息素的氘标记前体（香叶基丙酮-D5）。当将其施用于雄性前胸时，前体中的标记被掺入到信息素成分中，这证实了前胸是信息素的产生部位，并且信息素成分是由香叶基丙酮生物合成的。
