Pea odorants guide host finding behaviour in pea moth: a new strategy for sustainable insect management

豌豆黑卷蛾（Cydia nigricana）是豌豆的重要害虫。需要开发对环境安全的虫害防治技术，因为可用于有效防治的杀虫剂很少。第一项研究表明，C。nigricana和豌豆的物候。我们建议研究豌豆植物和豌豆蛾之间的嗅觉空间，旨在识别挥发性的线索，编码主机识别和主机发现在豌豆蛾女性，并实际使用这些化合物的安全管理豌豆蛾。昆虫与植物之间的交流，包括寻找寄主、交配和产卵。行为活跃的寄主植物信号的识别将使一个有效的方法，直接豌豆蛾控制的发展。此外，豌豆植物挥发物排放的时间和生理变化的特点将进行研究，以评估育种豌豆的抗虫草食动物的潜力。预期的产出是改善豌豆蛾和其宿主植物之间的化学通讯的知识，以及深入了解豌豆次生代谢产物的生物化学和豌豆蛾生物学和生态学之间的联系。将评估豌豆植物挥发物用于直接和间接豌豆蛾管理的潜在用途。

The pea moth Cydia nigricana (Lepidoptera: Tortricidae) is the key pest of pea Pisum sativum. Environmentally safe pest control techniques need to be developed since few insecticides are available for efficient control. First studies demonstrate a strong correlation between the seasonal flight period of C. nigricana and the phenology of pea. We propose to study the olfactory space between pea plant and pea moth, aiming at the identification of the volatile cues that encode host recognition and host finding in pea moth females, and the practical use of these compounds for safe management of pea moth. Communication between insect and plant regarding host finding, mating and egg laying will be investigated. The identification of behaviourally active host plant signals will enable the development of an effective method for direct pea moth control. In addition, the characterisation of temporal and physiological variation in pea plant volatile emission will be studied to evaluate the potential of breeding pea for resistance to insect herbivores. The expected output is improved knowledge of chemical communication between the pea moth and its host plant, as well as insights into the linkage between the biochemistry of the pea secondary metabolites and pea moth biology and ecology. The potential use of pea plant volatiles for direct and indirect pea moth management will be evaluated.
