植食性昆虫的寄主选择机理及行为调控策略

Host-plant selection mechanisms and behavioural manipulation strategies of phytophagous insects

害虫是影响农作物生产的重要因素,过度使用化学农药已带来严重的"3R"问题。为了长期有效地控制害虫的危害,基于植食性昆虫寄主选择机制的行为调控策略已成为害虫治理研究的重要方向。天然植物资源(如驱避植物、诱集植物与诱集枝把)、物理模拟材料(如诱集色、驱避色与诱集模型)和人工合成物质(如引诱剂、驱避剂、刺激剂与抑制剂)等研发工作皆取得了突破性的进展。除单一措施的使用外,多种诱集措施协同利用的"诱集+诱集"策略、诱集措施与趋避措施结合使用的"排斥-诱集"策略也已被广泛应用。

Insect pest is one of the most important factors adversely affecting the development of crop production, and the control method intensively depending on insecticide application has brought serious 3R （residue, resistance and resurgence） problems. The novel control strategy based on the behavioral manipulation of phytophagous insects has become a main research field in recent decades for sustainable management of crop pests. Many trap and repellent techniques derived from the natural plant resources （ e. g. trap crop, repellent crop and trap twig bundle）, physical stimulant materials （e. g. trap color, repellent color and trap model） and synthetic compositions （e. g. attractant, repellent, stimulant, deterrent） have been developed successfully. Beside the single trap strategy, the pull-pull strategy combining different trap measures and the push-pull strategy integrating the utilization of trap and repellent measures, have been widely exploited for pest management in agricultural production.
