摘要: 对刺桐姬小蜂成蜂生殖系统进行解剖研究,并观察其产卵行为.结果表明:雌性生殖系统由1对卵巢、1对侧输卵管、中输卵管、受精囊和外生殖器等组成.雄性生殖系统由1对睾丸、1对输精管、1对附腺、射精管和阳茎等组成.雌成虫的每个卵巢平均有卵巢管9~13条,每条卵巢管平均有卵3~7粒,卵巢管内的总卵数平均为54~182粒.刺桐姬小蜂的产卵过程可分为寻找产卵位置、穿刺与试探、产卵、休憩与梳理4个步骤.Abstract: The reproductive system of Quadrastichu erythrinae Kim adults was studied anatomically.The insect's oviposition behavior was also observed.The reproductive system consisted of internal reproductive organs and external genitals.The female adult had a pair of ovaries,a pair of lateral oviducts,a median oviduct,a spermatheca and an ovipositor.The male adult had a pair of testes,a pair of vas deferens,a pair of accessory glands,an ejaculatory duct and a penis.On the average,there were 9-13 ovarioles in an ovary and 3-7 ova in an ovariole,thus,a total of 54-182 ova in a pair of ovaries.The oviposition process included 4 steps,i.e.,locating egg laying place,puncturing and probing,egg depositing,and resting and cleaning.
