| 摘要: |
| 在２５℃恒温、１４．５～１５．０ｈ光照条件下，比较了杏、苹果、枣、桃、酸枣、山楂、海红、石榴等８种寄主上桃蛀果蛾越冬幼虫出土和成虫羽化的时间差异，并进行了杂交试验。结果表明，幼虫出土和成虫羽化时期在寄主间差异明显；不同寄主来源的成虫间容易杂交，并产生可育的Ｆ1代。Ｆ1代滞育率差异悬殊，表明不同寄主上的桃蛀果蛾临界光周期有差异。 |

| Abstract: |
| Experiments on the season ality and crossing of the peach fruit,moth,
Carposina sasakii Matsumura,among different host plants were conducted in lab at a
constant temperature of 25℃ and a photoperiod of 15 L:9 D.The results show that the
seasonal histories of the moth differ markedly among various plants,but are synchronized with the fruiting phenology of the very plant the moth originates from.The moths
from different plants are easy cross and produce fertile F1 offsprings.The diapaucing incidences of the grown larvae on different plants differ greatly under the same condition,
suggesting that have different photoperiodic responses. |
