摘要
蝗虫具有聚集为害的特征。群居型蝗虫形态、生理、生化、行为等与散居型明显不同。蝗虫的密度、资源的空间分布方式、化学信息素和特定行为均能够引起蝗虫聚集行为反应。蝗群聚集后,通过遵守简单的行为规则,形成了一个高度有序的复杂系统,在这个有序的复杂系统里群体蝗虫能够取得散居个体不能获取的生态效益。
Locusts show aggregation behaviors in the fields. Solitary and gregarious locusts differ in many traits, such as morphology, physiological and biochemical characteristics and behaviors. The aggregation behavior is closely correlated with the density of locusts, distribution patterns of resources, pheromone and special action of locusts. After locusts crowed, movement of locust swarm in migration follows a complex system based on simple laws. Individuals within the group highly align collective motion. The highly ordered mechanism was beneficial to extend useful information in locust group so that the whole population could approach the largest ecological bene- fits.
