Abstract
Adult emergence in Contarinia sorghicola (Coq.) in fields of sorghum in California is a single-phase diel rhythm with peak eclosion 1-2 h after sunrise. Males began emerging 30-45 min earlier than females and by the time the latter reached peak numbers, male emergence was 85% complete. Males began emerging at 55-60 deg F and females at 65-70 deg F. Emergence of both sexes ceased at 95 deg F. The sex ratio was near 1:1 early in the season (August) but by October females outnumbered males by about 2:1. Females dispersed to susceptible florets and oviposited until they died. Males continued to swarm round head from which they had emerged and were not associated with blooming heads
