Greenhouse and field experiments indicated that when the adult female of Atherigona varia var. soccata Rondani was given a choice between exotic and Indian sorghum varieties for oviposition, the former were highly preferred. Ovipositiona1 preference was manifested in a higher average number of eggs per plant and a higher percentage of plants infested with eggs. Damage as measured by percentage of dead hearts was significantly higher on exotic than on Indian varieties where flies were offered a choice; when there was no choice for oviposition, exotic and Indian varieties were damaged equally. Varieta1 differences affected larval survival and adult emergence of this fly.
