摘　　要：通过室内饲养观察和解剖云斑天牛雌虫生殖系统,研究了单次和多次交配对云斑天牛雌虫精子数量的消耗、产卵量、产卵历期和寿命的影响,并对云斑天牛雌虫生殖系统、精子形态及精子在雌虫生殖系统中的分布动态进行了研究。结果表明,多次交配的云斑天牛雌虫交配-受精腔内的精子数量长期保持在80万个左右,而单次交配的云斑天牛雌虫交配-受精腔内精子数量随着天数的增加而下降。多次交配的雌虫产卵量(31.44粒)和产卵历期(30.12d)都显著大于单次交配雌虫的产卵量(27.88粒)和产卵历期(25.75d)(P<0.05);多次交配的雌虫寿命低于单次交配的雌虫,但两者差异不显著(P>0.05)。The effects of single and multiple mating on quantitative depletion of spermatozoa and fecundity in Batocera horsfieldi Hope were investigated by dissecting bursa coplatrix-spermatheca and observting the biological characteristics in the laboratory.The reproductive systems of the female,spermatozoa morphology and dynamic distribution of spermatozoa in female reproductive system were also described in this paper.The results showed that about 800 thousand spermatozoa were always retained in the bursa coplatrix-spermatheca of multiple mating females,but the amount of spermatozoa declined according to the days extension after copulation in the bursa coplatrix-spermatheca of single mating females.The fecundity（31.44）and the period of reproduction（30.12 d）of multiple mating females were significantly higher than the fecundity（27.88）and the period of reproduction（25.75 d）of single mating females（P0.05）.However,the longevity were not significantly different between multiple and single mating females（P0.05）.
