摘    要:研究东亚飞蝗孤雌生殖和两性生殖的生殖特性,为飞蝗种群动态的预测及蝗灾的防治奠定基础。通过室内罩笼饲养试验,对东亚飞蝗孤雌生殖和两性生殖寿命、死亡率、产卵量及产卵时期进行了比较。研究结果表明,进行孤雌生殖的雌性成虫平均寿命显著长于两性生殖,死亡高峰期比两性生殖延后10 d左右。孤雌生殖平均每头雌虫产卵量为1.14块,而两性生殖为2.96块,两者存在极为显著的差异(P〈0.01)。而且两性生殖的产卵有明显的高峰期和周期性,孤雌生殖也有高峰期和周期性,但是高峰值显著低于两性生殖。可见,进行孤雌生殖的东亚飞蝗比进行两性生殖的生存力强但产卵能力弱。该研究结果有助于更为全面地了解飞蝗的生殖特性,也有助于了解飞蝗种群变动规律。

关 键 词:东亚飞蝗  孤雌生殖  产卵量  寿命  死亡率  产卵周期

Abstract:This paper reported a laboratory study on the comparison of lifetime,death rate,egg laying amount and egg laying period of bisexual reproduction and parthenogenesis.The results showed that mean lifetime of the parthenogenesis females was significantly longer than that of bisexual reproduction females(t-test,P<0.05),and the peak of death of the parthenogenesis females was later than that of bisexual reproduction.Most importance was that parthenogenesis female lays 1.14 pods per individual,significantly less ...
Keywords:Locusta migratoria manilensis  parthenogenesis  reproduction capacity  lifetime  mortality  periodical reproduetion
