| 摘 要： | 通过室内饲养小地老虎,研究了交配对其成虫寿命和繁殖的影响.结果 表明,小地老虎成虫的寿命随其交配状况而有所变化,无论雌蛾还是雄蛾,未能得到及时交配时,则寿命稍长些,交配过的雌蛾产卵前期缩短、产卵期延长、产卵量增大.小地老虎的交配次数对其产卵量和幼虫孵化率有明显的影响,0次交配的产卵量最低,并且产的是不育卵,均不能孵化;随着交配次数的增加,其产卵量和幼虫孵化率都显著增大.

| Abstract: | The effects of mating times on longevity and reproduction of Agrotis ypsilon were studied in the lab.The results showed that the longevity of Agrotis ypsilon is closely related with their mating times.The unmated adults live longer than mated ones and the females live longer than the males.The mated females had characteristics of a shorter ovipositing prophase,a longer ovipositing period and larger ovipositing quantities.The mating times could distinctly affect the adult's ovipositing quantities and the lar... |
