摘要
寄生于蝗虫的厦门卵索线虫（Ｏｖｏｍｅｒｍｉｓｘｉａｍｅｎｅｎｓｉｓ）生活史周期为一年，流行时间为４～１０月，但在６～７月感染率为最高。在本种线虫流行区内，单位面积草地上蝗虫虫口数比非流行区明显降低，对蝗虫种群数量有显著的自然控制作用。
Completing one time of life cycle of Ovomermis xiamenensis require one year.In Xiamen,five species of locusts were served as the natural hosts, namely,Oedaleus abruptus,Aiolopus,tamulus Trilophidia annulata Acrida cinerea and Atractomorpha sinensis. The parasiticlarvae could be collected from the body cavity of the hosts from April to October,but its highestpeak was found to be June to July, Thereby, the infested locusts were retarded in their develop-ment,and the females were usually fOund to be sterile.Our observation showed that the emer-gence of the parasite could cause the death of the locust.The mermithid was suitable for use inthe biocontrol against locusts.
