| 为明确延迟交配对马铃薯块茎蛾 Phthorimaea operculella 的影响，在室内条件下，分别对初羽化未交配的马铃薯块茎蛾雌虫、雄虫及雌雄虫同时延迟 1 ～ 5 d 配对饲养，研究不同延迟交配处理对该虫产卵量、卵的孵化率及 雌雄成虫寿命的影响。结果表明，从产卵量来看，分别将雄虫或雌虫延迟 1 ～ 3 d 交配对产卵量无显著影响，而延迟 4 和 5 d 交配能显著降低其产卵量，其中雄虫分别延迟 4 d 和 5 d 交配后使单雌产卵量分别降低了 20.50% 和 42.00% ，雌虫分别延迟 4 d 和 5 d 交配后单雌产卵量分别降低了 26.01% 和 35.79% 。当将雌雄同时延迟 1 ～ 2 d 交 配，对单雌产卵量无显著影响，而延迟 3 d、4 d 和 5 d 交配时，产卵量分别降低了 12.50% 、23.84% 和 44.57%。 从卵的孵化率来看，延迟 1 ～ 5 d 交配对卵的孵化无明显影响。从成虫寿命来看，不同延迟交配对雌雄虫的寿命均无显著影响。由此表明，马铃薯块茎蛾延迟 3 d 或4 d 后交配有利于降低其产卵量，因此可通过在田间设置性诱剂以干扰马铃薯块茎蛾正常交配来降低产卵量，从而达到控制田间马铃薯块茎蛾下一代虫口数量的作用。 |

| To clarify the effects of delayed mating on potato tuber moth，Phthorimaea operculella，the effects of the newly emerged adults of potato tuber moth were reared for 1 ～ 5 days on fecundity，hatching rate and longevity of male and female adults were compared after different delayed mating treatments ( delayed female，delayed male，delayed female and male) under indoor conditions. The results showed the delay of mating for 1 ～ 3 days had no significant effect on the fecundity of both females and males，but the fecundity of males decreased by 20.50% and 42.0% ，the delay of females decreased by 26.01% and 35.79% when the mating was delayed for 4 and 5 days，respectively. The simultaneous delay of mating by 1 ～ 2 days had no significant effect on the fecundity per female，but when the mating was delayed for 3，4 and 5 days，the fecundity decreased by 12.50% ，23.84% and 44.57% ，respectively. From the perspective of egg hatching rate，the delay of 1 ～ 5 days had no significant effect on egg hatching. In terms of adult longevity，different delayed mating days had no significant effect on the longevity of males and females. The delayed mating for 3 or 4 days was beneficial to reduce the fecundity of potato tuber moth. Therefore，the fecundity of potato tuber moth can be reduced using sex attractants in the field by interfering with the normal mating of potato tuber moth，which can be used to control the population of the next generation of potato tuber moth in the field. |
