n African Entomology - Assessment of damage by (Meyrick) (Lepidoptera : Tortricidae) in litchi orchards in Mauritius

Volume 16, Issue 2
  • ISSN : 1021-3589



Patterns of damage by (Meyrick) (Lepidoptera : Tortricidae) on litchi fruits, 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 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.
