Abstract

Some species of Coleoptera and Diptera are specialist predators of adelgids. Previously, we reported our survey of predacious Coleoptera on hemlocks in Japan (Shiyake et al. 2008). Two of these beetles, Sasajiscymnus tsugae and Laricobius sp. nov., have been exported to the U.S. for biological control. Here, we provide the first report of Diptera collected in Japan from its native hemlocks, Tsuga sieboldii and T. diversifolia.
