| 摘 要： | 在观察叶甲科昆虫生物学特性的工作中,我们曾发现过鸡血藤黄叶甲 Gonioctena fulva(Mots)伪胎生的生殖方式,即每次生殖时,常先产一粒卵,再胎生出幼虫。1984年初夏,又发现同一属的十三星角胫叶甲 Gonioctena tredecimmaculata(Jacoby)营胎生生殖,这种生殖方式在叶甲科中是少见的。为此,我们于1984—1985年对其生物学特性作了较系统的观察,结果报道如下。

| Abstract: | The beetle Gonioctena tredecimmaculata(Jacoby)is a defoliator of Puerarialobata(Willd)Ohwi.It has one generation per year.The overwintering adultsbegin emerging from the soil in late April and soon start to mate.Females beginviviparity 5 to 6 days after first mating.Each female may depoist 3 to 6larvae per day and with a total of about 22 to 58.The larvae,which pass throughfour instars,require about 10 to 12 days in May and 13 to 16 days in June toreach the pupal stage.The pupal period lasts 5 to 6 days.New adults beginappearing in early June and begin entering into soil for aestivation and hiber-nation in early July after feeding.The life of adults varies from 353 to 379days.Some individual females can live 415 days. |
