Can trapping control Asian paper wasp (Polistes chinensis antennalis) populations?
Asian paper wasps reach very high densities in some areas of the far north of the North Island, and concerns about their impact on native biota have led to a search for potential control methods. We simulated the effects of kill-trapping adults by manually removing either 50% or 75% of adults from nests and comparing subsequent counts of adults and capped pupal cells with paired untreated nests. Five weeks after treatment, the 50% removal group had an average of c. 29% fewer wasps than the untreated group, while the 75% removal group had c. 34% fewer than the untreated group.
