Ovarioles are smooth, gradually widening white tubes with different stages of eggs. The ovarioles were gently removed, and the right and left ovarioles were separated and counted the ovarioles. We observed that the ovaries of laying queens were extended from second abdominal up to fourth abdominal segments. Each ovariole is supplied with tracheae. The tracheae are auriferous types characterized by coating spiracle tubules with permeable cuticle, which may bring the tracheal air into close contact with haemolymph.
