This news (May 21) The Insect Ecology and Pest Management Discipline Group of the Institute of Forestry of the Chinese Academy of Forestry recently published a research paper in the entomological journal Journal of Applied Entomology, and the important research results have clarified the chemical ecological relationship between the host monoterpene and the spruce octodonis forest.

Spruce eight-toothed beetle is a very important dry moth pest in the Eurasian spruce forest ecosystem, and its population outbreak can lead to large-scale death of spruce forests. There is a complex chemical ecological interaction between the host plant monoterpene and the outbreak of spruce octodonite populations, especially the ecological interaction mechanism between host resistance and spruce octodon beetle overcoming host resistance and successful colonization.
In this study, insect toxicology determination, chemical analysis and behavior determination methods were used to clarify the ecological functions of three spruce monoterpenes in the outbreak of spruce octodonis populations. Three host monoterpenes exhibited great differences in toxicity and metabolism in spruce octodonde, and the metabolites had different biological significance.
This study not only reveals the ecological versatility of the host monoterpene in the process of regulating the dynamic population of spruce octodontic beetle, but also elucidates the synergist and ant ant of spruce eight-toothed beetle population aggregation, which can be directly applied to the regulation of spruce octodon beetle population, and provide technical support for improving the comprehensive management of spruce eight-toothed beetle population. The first author of the paper is Fang Jiaxing, a doctoral candidate at Senhuan Senbao Institute, and the corresponding author is Kong Xiangbo, a researcher at Senhuan Senbao Institute. The work has been jointly funded by the basic scientific research business fund project of the central public welfare scientific research institute and the national "13th Five-Year Plan" key research and development plan project.
