朝鲜毛球蚧雄虫预蛹期和蛹期生殖系统发育研究
Reproductive System Development of Male Prepupal Instar and Pupal Instar of Didesmococcus koreanus Borchsenius
摘要
Abstract
In order to study the development of the reproductive system of the"pre-pupa"and"pupa"of Didesmococcus koreanus Borchsenius,the morphological characteristics during the process from the 2nd instar nymphs to male adults were observed under the microscope(Olympus).The results showed that:the prepupal duration is 2-4 days,and the pupal duration is 4-6 days;The male reproductive system is composed of a pair of testis(T),a pair of vas deferens(vd),ejaculatory sac(es),ejaculatory duct(ej),and a pair of mesadenia(me).At different stages of development,the morphological structure of the male reproductive system of the D.ko-reanus was observed a series of changes.At the end of the 2nd instar nymphs,the apex of the T is enlarged and full of white content.In prepupal stage,the base of the T became thicker,the contents showed light and dark stripes,and the length of the vd and ej in-creased.The stripes in the T of the pupal stage disappear and the contents are gel-like.The T of the male adult became distorted,with a pointed end and enlarged base.The es of the male adult was enlarged and filled with white gelatinous spermatozoa.关键词
