セジロウンカ成虫腹部の外形的所見と卵巣発育

抄録

Abdominal corpulence of the S. furcifera female adult was classified using 5 scores (0 to 4) and the correspondence of this and ovarian development was studied. More than half of healthy females with scors of ≥ 3 at the macroptera and ≥ 2 at the brachyptera were able to lay eggs. Causes of abdominal corpulence are important in determining sexual maturity. The percentage of mature females based on abdominal scores related positively to the insect's population.
