Jassids are polyphage pests that occur on several host plants. These insects were minor pests on okra and eggplant in Côte d’Ivoire. However, during this season, attacks, similar to those observed on cotton for more than a decade, were reported by farmers. Their invasion on these crops has raised concerns among farmers who also grow cotton. A mission was undertaken to identify the jassid populations that had appeared on these crops. It led to the identification of three species: Jacobiasca lybica (Bergevin & Zanon, 1922), Jacobiella facialis (Dworakowska, 1972) and Amrasca biguttula (Shiraki, 1913). The most abundant species were J. lybica (49.4%) and A. biguttula (47.8%). The species J. facialis was identified only on eggplant with a proportion of 2.8 %. At least two of the species cohabit in the same field. The cohabitation of these species reflects the virulent character of the attacks. A strong outbreak was observed during the period from June to July. This study therefore provides important information for decision-making.
