A study was carried out from April to December 2013 in the south of Cte d'Ivoire for to evaluate the damage of the shoot and fruit borer: Leucinodes orbonalis Guenee (Lepidoptera :Pyralidae) on three varieties of eggplant (Djamba F1, Kotobi and N'drowa issia). It consisted in counting infested and healthy shoots on randomly selected 24 plants fromeachsub plot. At the fruiting stage, besides enumerating the attacked shoots, the healthy and attacked fruits were also counted. The percentages of the infested shoots varied according to the varieties and phenological stages. The highest shoot infestations were registered at the fruiting stage for each variety with 53.07 0.97% (N'drowa issia); 56.29 1.84% (Kotobi) and 66.59 1.62% (Djamba F1) respectively 159, 173 and 166 days after transplanting (DAT). The highest fruit infestations were obtained 166 DAT (N'drowa issia: 40.04 1.67 %) and 173 DAT (Kotobi: 69.89 1.16% and Djamba F1: 82.67 0.52%). Significant correlations between abiotic factors and infestations of shoots and fruits have been registered.
