The blue gum chalcid,Leptocybe invasaFisher & LaSalle (Hymenoptera: Eulophidae), causes galls onEucalyptusspp. leaf midribs, petioles and stems.Biological aspects need to be studied to assist in developing management strategies and to maintain this insect in the laboratory to rear the parasitoidSelitrichodes neseriKelly & La Salle (Hymenoptera: Eulophidae) that depends on having a supply ofEucalyptusseedlings infested byL. invasa.We evaluated the longevity and survival ofL. invasaindividual non reproductive females fed with six different diets (pure honey, 50% honey solution, pure honey plus eucalyptus leaves, eucalyptus leaves, distilled water, or no food) and seven different temperatures (10, 14, 18, 22, 26, 30 and 34 °C).Leptocybe invasafed with 50% honey solution and reared at 14 or 18 °C showed the greatest longevity and survival.
