Biocontrol introduction

Target pest: Gonipterus scutellatus (Coleoptera: Curculionidae), gum tree weevil

Agents introduced:

General comments:

Cameron et al. (1989) - several biological control agents were introduced to New Zealand for the gum tree weevil Gonipterus scutellatus [subsequently identified as G. platensis - see Mapondera et al. (2012) entry below].

Mapondera et al. (2012) - Gonipterus 'scutellatus' is a complex of externally similar species, though well distinct in their male genitalia as well as genetically. None of the invasive Gonipterus species outside of Australia represent G. scutellatus (which is a comparatively rare species restricted to Tasmania). The species present in France, Spain, Portugal, California, Hawaii, Chile, Argentina, Brazil, Uruquay, New Zealand and Western Australia is G. platensis (Marelli), which is native to Tasmania but had not been described from the Australian mainland.

See the entry for Gonipterus platensis for biological control details of the species of Gonipterus present in New Zealand.
