Agent introduced: Volucella inanis (Diptera: Syrphidae)
Import source: south-western UK
Landcare Research (2017i, 2018l) - thirteen Vespula nests collected in southern UK in late-summer 2017 were imported into quarantine at Lincoln, Canterbury. Parasitoids present included 50 V. inanis larvae. The intention was to rear these for host range testing; however, none of the imported individuals survived the overwintering process in quarantine.
Impacts on non-targets:
Brown (2020) - larvae of V. inanis are obligate ectoparasitoids of Vespula spp. (family Vespidae) wasp larvae. The evidence for this conclusion comes from literature sources, behavioural studies, and surveys in Europe. There are no native wasps in the family Vespidae in New Zealand. The highly specialised ecology and life history of V. inanis preclude other social Hymenoptera such as honeybees, bumblebees and ants present in New Zealand from serving as hosts. In a laboratory trial, V. inanis larvae (n = 6) did not attack larvae of the bumblebee Bombus terrestris, but after being moved near wasp comb they quickly found and attacked V. vulgaris larvae.
