【摘要】 探讨了植物体内几丁质酶与昆虫种群动态的关系，发现几丁质酶对蚜虫的发育、存活和生殖都有明显的影响，并最终调节种群的动态．实验结果显示，几丁质酶对若蚜的影响比成蚜大，并与蚜虫的翅型变化关系密切，表现了其作为抗性物质所具有的抵御虫害的功能．更多还原

【Abstract】 Experiments were carried out to study the relationship betweenchitinase in Viola faba leaves and Aphis craccivora population dynamics.It is found that chitinase has an obvious effect on the developmental duration, survival rate, reproduction rate of Aphis craccivora and in thelast analysis regulates the insect population dynamics. The resules alsoshows that the chitinase has a stronger effecton nymphs rather than theadults and it is closely related formation of the ophid.更多还原
