Abstract

Etablissement de la cochenille farineuse de l’ananas Dysmicoccus brevipes (Hemiptera: Pseudococcidae) en Italie Cet article signale l’etablissement de la cochenille farineuse de l’ananas Dysmicoccus brevipes (Hemiptera: Pseudococcidae) en Italie. Les differents stades de developpement de la cochenille trouves pendant l’hiver en Sicile sur les racines aeriennes de palmiers dattiers adultes (Phoenix dactylifera L.) indiquent que D. brevipes a une forte capacite a resister et a poursuivre son developpement m^eme a basse temperature. L’etablissement de cette cochenille en Sicile pourrait representer une menace serieuse pour les vignobles, compte tenu des deg^ats observes en Amerique du Sud sur le cultivar ‘Italia’, qui est l’un des cultivars de raisin de table les plus largement cultives en Sicile.
