摘  要：
在寄生蜂行为生态学研究中,通常将寄主体型大小作为寄主品质的主要性状来探究寄生蜂的搜寻行为机理,而忽略寄生蜂体型大小的意义。为揭示聚寄生蜂雌蜂体型大小对其产卵决策的影响,在严格控制寄主菜粉蝶Pieris rapae蛹体型大小(体重)的情况下,于室内观察了不同体型大小的蝶蛹金小蜂Pteromalus puparum雌蜂的产卵行为,并调查了子代蜂数量(窝卵数)、性比和体型大小的变化。结果表明:雌蜂在寄主上的驻留时间随其自身体型增大而缩短,但随寄主体重增大而延长。窝卵数和余卵量受到雌蜂体型大小的显著影响,均随雌蜂体型增大而显著增加(P<0.05);但子代蜂性比不受雌蜂体型大小的显著影响(P>0.05)。子代雌、雄性体型大小均与雌蜂体型大小无关,但子代雌蜂体型随寄主体重增大而增大。结果证实,雌性蝶蛹金小蜂体型大小影响其部分产卵决策。因此,在建立聚寄生蜂产卵决策模型中应考虑雌蜂体型大小这一重要变量因素。

摘  要：
Host body size,one of host quality attributes,is often a major focus of the study of foraging behavior in parasitoid behavioral ecology.But little emphasis was placed on parasitoid body size.To investigate the effects of female body size on oviposition strategy in the gregarious parasitoid,Pteromalus puparum,experiments were conducted in laboratory under the stringent control of host(Pieris rapae pupae) body size to observe the oviposition behavior and examine the changes in the clutch size,sex ratio,and body size of the progeny parasitoids.The results indicated that the residence time of females on host pupae decreased with increase of their body size,but increased with host body size.Larger females gave birth to more offsprings with more eggs reserved after a bout of oviposition.Sex ratio and body size of offspring parasitoids were not affected by female body size,but the body size of female offsprings increased with host body size.The results confirm that female body size may affect part of the oviposition strategy in P.puparum,and should therefore be incorporated into models of oviposition strategies for gregarious parasitoids as an important variable.
