Abstract

The average number of ovarioles in three species of grasshopper reared in the laboratory was: Melanoplus sanguinipes (F.) 28.1 ± 2.4, M. bivittatus (Say) 80.1 ± 10.1, and Camnula pellucida (Scud.) 27.6 ± 2.7. Not all ovarioles developed mature eggs; some eggs were resorbed. The number of egg rudiments in the ovarioles increased somewhat with age of the grasshopper and would not limit the number of eggs laid. Some abnormalities are described and some discussion of the corpus luteum is included, particularly the relationship between a pigmented corpus luteum and ovulation.
