    • Abstract


      An extremely low egg output, almost approaching zero level, and with no sign of viability, occur inEarias vittella (F.) when the females are coupled for mating with antennectomised males or if both sexes paired for coition are wingless. However, sexual union arranged between normal females and males whose both wings or only fore or hindwings are excised facilitates these insects to deposit fertile eggs whose number, however, always remains markedly lower (more so when the males in the breeding pairs are without hindwings) in comparison to that recorded for mated females in pairs where both sexes are normal.
