New State Record of the Psyllid Heterotrioza chenopodii (Reuter, 1876) (Hemiptera: Psylloidea: Triozidae) for Hawaii

Abstract

We report the first state record of a widespread palaearctic psyllid species, Heterotrioza chenopodii (Reuter, 1876), for the state of Hawaii. This species belongs to a small genus of 13 species feeding exclusively on host plants in the plant family Amaranthaceae (Lauterer 1982, Burckhardt and Ouvrard 2012, Ouvrard 2019). Recorded host genera are Atriplex, Beta, Chenopodium, and Spinacia (Ouvrard 2019). In Hawaii, a likely host plant is Atriplex suberecta, and possibly A. semibaccata and Chenopodium oahuense.
