Fruit flies were monitored at two different localities in litchi orchards to determine which species occurs the most abundantly. Monitoring was conducted in orchards near Nelspruit and Malelane. Sensus traps with 8-caryophyllene as well as a milk bottle trap with a protein hydrolysate were used. The dominance of the Natal fruit fly, Ceratitis rosa Karsch, in the Sensus as well as in the milk bottle traps, suggested that this species could be responsible for most damage caused by fruit flies in litchi orchards. C rosa was the most abundant species in both areas. The Marula fruit fly,
Ceratitis cosyra (Walker), does not seem to be of any importance in litchi production.
