Patterns of damage by Cryptophlebia peltastica (Meyrick) (Lepidoptera: Tortricidae) on litchi fruits, Litchi chinensis Sonnerat, at varying stages of maturity were determined in four orchards in Mauritius during two consecutive litchi seasons. Damage was found to start at a very early stage in the season, when fruits were 3 mm in diameter. In three orchards there were no significant differences in damage incidence by C. peltastica during the fruiting season. In the fourth orchard, a significant increase in fruit damage was observed at the end of the season. Damage levels of up to 20 % on litchi fruits were observed when no control actions were implemented.
