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.

Abstract: (french)
Les jassides sont des ravageurs polyphages que l’on observe sur plusieurs plantes hôtes. Ces insectes constituaient des ravageurs mineurs sur le gombo et l’aubergine en Côte d’Ivoire. Cependant, au cours de cette saison, des attaques, similaires à celles observées sur le cotonnier depuis plus d’une décennie, ont été signalées par des producteurs. Leur invasion sur ces cultures a suscité des inquiétudes chez les producteurs qui pratiques également la culture du coton. Une mission a été entreprise afin d’identifier les populations de jassides apparues sur ces cultures. Elle a conduit à l’identification de trois espèces: Jacobiasca lybica (Bergevin & Zanon, 1922), Jacobiella facialis (Dworakowska, 1972) et Amrasca biguttula (Shiraki, 1913). Les espèces les plus abondantes sont J. lybica (49.4 %) et A. biguttula (47.8 %). L’espèce J. facialis a été identifiée uniquement sur l’aubergine avec une proportion de 2.8 %. Au moins deux des espèces cohabitent dans un même champ. La cohabitation de ces espèces traduit le caractère virulent des attaques. Une forte pullulation a été observée durant la période de juin à juillet. Cette étude met donc à disposition des informations importantes pour les prises de décision.
