Resumen en español

The aim of this paper is to provide information regarding a new registry of mealybugs and host plants in the Sancti Spíritus province of Cuba between 2005-2015. In this time period, 10 genera and 21 species of mealybugs were found (16 new records) in the ecosystems of the area studied by the Fomento Territorial Plant Protection Station. These new registries were found on 130 host plants species (40 previously unrecorded for Cuba), from 57 botanical families. This represents a notable increase in the number of genera and species of mealybugs present, as well as in the number of host plants, many of which were previously unreported in Cuba.
