Tougher stance this season
The Ministry for Primary Industries (MPI) will be getting tough on brown marmorated stink bugs (BMSB) this season.
If biosecurity officers determine one is infested with stink bug, it will be prevented from discharging its cargo and directed to leave New Zealand.
Steve Gilbert, director border clearance services, Biosecurity New Zealand, said it had also introduced a very low threshold for determining contamination.
It will be compulsory for certain types of cargo to be treated before arrival to remove the risk of hitchhiking stink bugs. Cargo such as uncontainerised vehicles and machinery will be assessed to make sure they are compliant before they’re allowed to be discharged. MPI will no longer direct contaminated vessels to undergo fogging with insecticide, which was introduced as an emergency treatment option in February following a spike in BMSB detections in vehicle carriers from Japan.
Last season biosecurity officers intercepted more than 2500 individual stink bugs at the border.
