Gum leaf skeletoniser Uraba lugens is native to Australia and is a common defoliator of Eucalyptus Uraba lugens was first recorded in New Zealand in 1992 and is now well established in the Auckland region As U lugens has the potential to damage Eucalyptus in New Zealand nochoice larval development trials were used to assess the ability of U lugens larvae to develop on 18 Eucalyptus species that are highly valued in New Zealand Eucalyptus nitens and E nicholii were the most suitable larval hosts
more » ... itable larval hosts as larval mortality was low and development time was brief Larvae reared on E fastigata had a rapid development time and high growth rates resulting in heavy female pupae although larval mortality was in the intermediate range Species that were least suitable for U lugens development included Corymbia maculata E microcorys the juvenile foliage of E globulus globulus and E globulus maidenii
