Selecting potential non-target species for host range testing of Eadya paropsidis

T.M. Withers, G.R. Allen and C.A.M. Reid

ABSTRACT

Classical biological control is proposed for Paropsis charybdis (Coleoptera: Chrysomelidae: Chrysomelinae), a eucalypt pest established in New Zealand. The Australian solitary larval endoparasitoid Eadya paropsidis (Hymenoptera: Braconidae) is under investigation. A potential non-target species list was compiled for host range testing. There are no endemic species of paropsines in the New Zealand fauna, only invasive pest beetles. The most closely related endemic beetles to the paropsines are Chrysomelinae in the genera Allocharis, Aphilon, Caccomolpus, Chalcolampra and Cyrtonogetus. Little is known about these species. New Zealand has also introduced 12 beneficial chrysomelid weed biological control agents, which include Chrysomelinae and their sister group the Galerucinae. One endemic beetle, six beneficial beetles and two pest beetles are listed as the highest priority species for host specificity testing.

Keywords: biological control, host specificity testing, Chrysomelidae, paropsine.
