Female reproductive system and ovarian development in Aprostocetus brevipedicellus(Hymenoptera:Eulophidae)
There are no reports on the ovary structure and development of Aprostocetus brevipedicellus both domestically and internationally until now.Here we observed the female reproductive system,egg morphology,and ovarian development characteristics of A.brevipedicellus.The results showed that the internal reproductive system of female A.brevipedicellus included a pair of ovaries,two lateral oviducts,one median oviduct,spermatheca and poison sac,etc.The female external genitalia comprised the ovipositor,ovipositor sheath,inner plate,and outer plate.Meanwhile,we found that A.brevipedicellus is synovigenic parasitoid.A few mature eggs were observed in the ovaries of newly emerged females,and the number of mature eggs and total eggs increased with the age of female adults when sufficient nutrition was available.The peak number of mature and total eggs was observed 72 h after emergence.Furthermore,the results showed that both the number of mature and total eggs were positively correlated with the body length of female A.brevipedicellus,with correlation coefficients of 0.936 and 0.941,respectively.These results provide a theoretical basis for scientific research and utilization of A.brevipedicellus.
