摘要
于不同温度与不同相对湿度组合条件下,比较了两性生殖品系及人工转染含沃尔巴克氏体的孤雌产雌品系松毛虫赤眼蜂的羽化率、寿命、繁殖力等生物学特性,以及高温和滞育贮藏对其生殖行为的影响。结果表明,在20℃与RH45%、78%、92%,以及25℃与RH45%、92%的组合下两性生殖品系松毛虫赤眼蜂的羽化率高于孤雌产雌品系松毛虫赤眼蜂;在20℃与RH45%及30℃与RH92%的组合下两性生殖品系松毛虫赤眼蜂的寿命高于孤雌产雌品系松毛虫赤眼蜂;其余温湿度组合下羽化率、寿命和繁殖力二者均无显著差异。高温和滞育贮藏均会使已获及沃尔巴克氏体的孤雌产雌品系松毛虫赤眼蜂在第二代中出现少量雄性个体,但继续培养仍会恢复为完全孤雌产雌生殖。
Under combinations of temperature （20, 25 and 30℃） and relative humidity （45%, 78% and 92 % ）, eclosion, longevity and fecundity between Trichogramma dendrolimi Matsumura （T. d） and T. dendrolimi infected by Wolbachia （T.d. （w）） were compared in laboratory. And effects of high temperature and dispanse storage on the reproduction behavior of the T. d （w） line were determined. Results show that under the combinations of 20℃ （RH45%, 78% and 92%） and 25℃ （RH45%, 92%）, eclosion of T. d was significantly higher than T. d （w）; in the combinations of 20℃ and RH45%, 30℃ and RH92%, longevity of T.d was significantly longer than T.d （w） ; but no significant differences were found in eclosion, longevity and fecundity between the two lines in other combinations. Under high temperature and dispause storage, a small number of male offspring occurred in the second generation in thelytoky line, but disappeared under continous rearing.
