Modification of fecundity and fertility during oogenesis by gamma radiation and/or ozone with a cytological analysis in the ectoparasitic wasp, Habrobracon juglandis (Ashmead)
… C to correlate by cytological examination of the ovarioles the effects of ionizing radiation and/or ozone on the germ cells at specific meiotic stages. The ovarioles from females exposed to 8 and 16 h ozone had gaps in the series of developing reproductive units and these abnormalities increased …

Studies on Conura torvina (Hymenoptera: Chalcididae) Reproduction and biology in Relation to Hosts in Brassica Crops
… Dissection of C. torvina ovaries indicated three ovarioles per ovary with a mean of 9.2 and maximum of 15 mature eggs per female. Host dissection indicated that a mean of 18 and maximum of 30 eggs could be laid per day. New eggs were produced as oviposition occurred. Significantly larger eggs were …
