植物对蝗虫行为及种群的调控作用

蝗虫食性广,取食量大,对植物的破坏作用极大.植物不仅是蝗虫食物的直接来源,还为其提供栖息场所,对蝗虫个体行为和种群动态均有重要影响.植物挥发物和次生代谢物质对蝗虫的取食、求偶、繁殖、产卵行为和个体生长发育等具有明显的调控作用.植被覆盖度能够直接影响蝗群的聚集度和迁移距离,同时蝗虫对产卵地的植被覆盖度也有严格要求,特别对...

Regulatory effects of vegetation on the behavior and population of grasshoppers

Locusts have a wide feeding habit and a large amount of food intake, which has a great destructive effect on plants. Plants are the food of locusts and provide them with habitats, which have an important impact on individual behavior and population dynamics of locusts. Plant volatiles and secondary metabolites have obvious regulatory effects on the feeding, courtship, reproduction, oviposition behavior and individual growth and development of locusts. Vegetation coverage can directly affect the degree of aggregation and migration distance of the first generation of locust swarms. At the same time, locusts have strict requirements for the vegetation coverage as their spawning grounds, especially having a significant impact on the spawning behavior of locusts in swarms. In order to provide a wider range of ideas for comprehensive management of locusts, we reviewed and expounded the effect of vegetation on locust behavior and population dynamics, and discussed the relationships between vegetation and the occurrence of locust plagues.
