Cucumber green mottle mosaic virus
This disease is new to Australia and infects watermelon, cucumber, melons, zucchini, pumpkin, squash, bitter gourd, bottle gourd and some species of closely related weeds.
For more information go to the section on Cucumber green mottle mosaic virus.
This disease is caused by the fungus Uredo rangelii and is considered part of the eucalyptus/guava rust fungi group.
Myrtle rust was first identified in New South Wales in April 2010 and has been detected in the NT.
Asian honey bee
The NT is on the alert for Asian honey bees, which are a significant threat to Australia and NT honey and pollination industries.
They can carry varroa, tropilaelaps and tracheal mites and can also spread other pests or diseases to European honey bees, which are used to produce honey.
Read more about the Asian honey bee alert and how to report sightings of unusual bees.
European foulbrood has been detected on a small number of bee hives in Katherine. This is a notifiable honey bee disease in the NT.
Read more about bee diseases and how to protect your bee hives.
Browsing ants were found at Darwin Port and two neighbouring sites in 2015. Browsing ants - Lepisiota frauenfeldi - are exotic and are not established in Australia. They form large colonies and eat and displace native ant species, as well as other insects in the infested area. They are not harmful to humans.
The bacteria Dickeya zeae was detected in pineapples on one property in the NT in 2016.
The grower has put voluntary quarantine arrangements in place on the property.
All commercial pineapple plantations in the NT have been inspected along with a number of local nurseries. There have been no further detections.
Growers should always maintain good biosecurity practices. For more information on how to minimise risks to your crops visit the Farm Biosecurity website.
