Thousands of trees in Hawaii have succumbed to EGW since 2005 and died within a few years of infestation. The endemic wiliwili tree, , an important component of Hawaii's dry forests and one of few deciduous native trees, were severely impacted by this wasp.

To improve performance of female wasps in biological control programs, we conducted a series of experiments to investigate male wasp reproductive performance and its role in female reproductive success. The results showed that D.
