Morphometric characterization of male genitalia is an important aspect for studying intraspecific
variation in Lepidoptera. In this study, size variation in the male genitalia of rice yellow stem borer
(YSB) Scirpophaga incertulas (Walker) collected from nine locations through sex pheromone traps was
examined. Measurements of male genitalial parts like uncus length (UL), uncus width (UW), valva length
(VL), valva width (VW), saccus length (SL), saccus width (SW), aedeagus length (AD) were considered.
Significant size variation was observed among the populations, and the measurements SL, SW, VL, VW,
UL, UW and AD contributed to about 16% to location variability. The results showed that all characters
except valva width was significantly different (p≤0.05) among the nine populations.
