摘　　要：通过应用高清数码摄相机手段,系统监测了蝶蛹金小蜂寄生黑纹粉蝶蛹的产卵习性。结果发现,蝶蛹金小蜂寄生黑纹粉蝶蛹的产卵过程可分为守卫、探查、产卵、整理4个阶段。蝶蛹金小蜂可以很好地寄生黑纹粉蝶蛹,暗期寄生产卵活动频次较少,光期后寄生产卵活动逐渐增加,寄生产卵活动呈现明显的昼夜节律。寄生产卵频次和时间分配主要集中在11:00—17:00,其中14:00—15:00为寄生蜂产卵高峰期。蝶蛹金小蜂寄生黑纹粉蝶蛹产卵活动频次分配率与产卵耗时分布呈正相关,单头黑纹粉蝶蛹体内产生的蝶蛹金小蜂后代数量随累计产卵时间和产卵频次增加而显著增多。随着寄主从预蛹发育到3日龄蛹,蝶蛹金小蜂单次寄生产卵耗时延长,且相对偏好选择在1日龄蛹体上寄生产卵。In this study, a digital camera was used to monitor the oviposition behavior of the parasitoid Pteromalus puparum Linnaeus on pupa of Pieris melete Ménétriés. The procedure of oviposition was summarized as guarding, probing, oviposition and cleaning. The oviposition activity showed a distinct circadian rhythm, with fewer activities at night and more activities at daytime. Oviposition occurred mainly during 11：00 to 17：00 and peaked between 14：00 and 15：00. In addition, oviposition frequency of P. puparum was positively correlated with time spent in oviposition. With the increase of total oviposition time and frequency, more offsprings were obtained. The time spent in oviposition increased with host pupal age. The female adults of P. puparum preferred fresh pupa（1 st day pupa） as host for oviposition.
