The transmission of sperm in the female reproduction tract of cotton bollworm,Helicoverpa armigera
摘要
Abstract
The transmission and distribution of sperm in the reproduction tract of mated female Helicoverpa armigera,were studied with Feulgen smear and microscope count methods.The results were summarized as follows:(1)Both eupyrene and apyrene sperms started their transmission from the spermatophore to spermatheca at 1.5 h after copulation,and finished this process in half hour.Thereafter,the number of sperms in spermatheca decreased gradually;(2)After transferred to spermatheca,the sperms stored in the utriculus in the form of sperm mass.No sperm was found in lagena;(3)Transportation of sperm to the spermatheca was achieved by means of rhythmic muscular contraction of the female reproduction tract.The active apyrene sperm was also believed to assist in the transmission of the eupyrene sperm.关键词
