Abstract

Orasema minutissima Howard (Hymenoptera: Eucharitidae) is recorded from the Hawaiian Islands for the first time. It has been established on the island of Hawai‘i since at least 2019. The wasp is a parasitoid of the immature stages of Pheidole and Wasmannia (Formicidae: Myrmicinae), both of which are significant pests on several of the Hawaiian Islands. Already found in substantial numbers, the wasp is a potential biological control agent for Wasmannia auropunctata, the Little Fire Ant.
