Confidence in stable isotopes to verify a high risk pest incursion as foreign or NZ established

Biosecurity outcome
Stable isotope (SI) signatures of origin will aid MPI decisions on the level of response needed for a new high risk, post-border pest detection, by providing supporting evidence of a locally breeding population or fresh overseas arrival.
The first evidence of whether the plant part (fruit, leaf, sap, wood) used for insect growth, and acquisition of its SI signature, influences use of that data
Science outcome
A novel statistically-based method of landscape isotope (isoscape) data to distinguish the origins of insects will be generated
