摘要
飞蝗存在着有趣的型变现象,即群居型、散居型以及介于二者之间的转型变。飞蝗不同的型相之间存在着一定的差异,包括生理生化、形态特征以及行为习性等多个方面。目前的研究表明,飞蝗的型变主要与虫口密度、内分泌及化学信息物质等有密切关系。研究飞蝗型变的影响因素及其调控机理,对揭示飞蝗的发生规律、加强防治工作具有重要意义。
There are interesting transitions among each polymorphism of Locusta migratora （Linnaeus）, namely gregarious, solitarious phrase and intermediate forms among or between them. The different phrases can be distinguished by physiological, biochemical, morphological and behavioral traits and closely correlated to insect density, endocrine and semiochemical substances as recently reported. The research on influencing factors and regulatory mechanisms of phrase polymorphism in Locusta migratora could make significant contributions to reveal its occurring rules and improve its control effects.
