Researchers complete world first wasp genome project

In a world first, New Zealand researchers have sequenced the genome of three wasps, two of which are invasive wasps in New Zealand, paving the way for new methods of control for these significant pests.

Genomics Aotearoa researchers working at the University of Otago and Te Herenga Waka–Victoria University of Wellington, alongside colleagues from the UK, Australia and California have successfully completed a three-year project to sequence and interpret the genomes of the common wasp (Vespula vulgaris), German wasp (Vespula germanica), and the western yellowjacket (Vespula pensylvanica).

This is the first genome produced globally. It is a major milestone in understanding the biology of Vespula wasps, which have spread across much of the world and are significant pests, affecting human health, economies and biodiversity.

Genomics Aotearoa Director Professor Peter Dearden, who heads the University of Otago team doing the research, explained vespine wasp populations can reach up to 40 nests per hectare, are very efficient predators of New Zealand's native insect species and compete for food with native birds.
