Project Summary Provide a description of the proposed action and purpose and need in 200 words or less. The HDOA with support from the Hawaiʻi Department of Land and Natural Resources, proposes the release of a eulophid ectoparasitoid, Aprostocetus nitens, to complement Eurytoma erythrinae for biocontrol of the erythrina gall wasp (EGW), Quadrastichus erythrinae, an invasive pest species that has attacked and quickly killed hundreds of Erythrina spp. trees in Hawaiʻi including the native wiliwili, Erythrina sandwicensis. Eurytoma erythrinae, a natural enemy of EGW, was collected from Tanzania and released in Hawaiʻi in November 2008 following rigorous specificity testing. Eurytoma erythrinae is an ectoparasitoid that attacks EGW by feeding on it larvae. Six months after release, E. erythrinae established successfully and wiliwili trees began to recover, however, damage by EGW on flowers, seed pods, and seedlings of wiliwili persists. Galls formed by EGW on flowers and seedling are usually small and scattered but E. erythrinae fares well only on large galls. This Draft Environmental Assessment supports the release of a second biocontrol agent, Aprostocetus nitens, to complement E. erythrinae to control EGW. Collected in EGW’s native region of Africa, A. nitens can complete development on a single EGW and survives well on small and large galls. Testing has proven A. nitens to be host specific to EGW.

This non-native species quickly spread to Erythrina species throughout the state, including wiliwili (Erythrina sandwicensis), a highly valued dominant species of Hawai‘i’s lowland dry forests (Figure 1). The infestation of Hawai‘i by Erythrina gall wasp has resulted in the defoliation and mortality of thousands of Erythrina trees throughout the state, and it was not until the approval and release in 2008 of Eurytoma erythrinae, a wasp parasitoid of Erythrina gall wasp, that wiliwili populations began to show signs of recovery. Ongoing monitoring of wiliwili has shown that inflorescences and seed pods are still being negatively affected by the gall wasp. A second biocontrol, Aprostocetus nitens, has been studied as a complementary biocontrol to E. erythrinae, and it is hoped that this species will further reduce the gall wasp’s negative impacts. The Hawaiʻi Department Agriculture (HDOA) is proposing to release A. nitens to reduce the impact of the gall wasp. This environmental assessment fulfills the requirements of the National Environmental Policy Act and the Hawaii Environmental Policy Act by detailing the results of host specificity and biological studies of A. nitens. An environmental assessment is needed to acquire the necessary state and federal permits for the release of this insect. Figure 1.
