Our most unwanted pests

06 September 2018

Fruit flies and Brown Marmorated Stink Bug (BMSB) are considered two of the biggest biosecurity threats to the kiwifruit industry and from September they are both in their highest-risk period for entry into New Zealand. A quick reminder of the damage these unwanted pests can do and what to look out for:

Fruit flies:

· High likelihood of entry - has crossed our borders many times before.

· Extended spread in Australia.

· Severe market access restrictions, especially for Queensland Fruit Fly, which is not present in nearly all kiwifruit markets.

· The high-risk season is now. Be on the lookout for the flies as well as the larvae in fruit.


· High likelihood of entry – particularly in shipping containers, cars and machinery, and passenger luggage.

· Significant production impacts for a wide range of crops.

· Early detection needed because this pest is extremely difficult to eradicate. It’s also a major nuisance pest infesting homes.
