Bactericera cockerelli was first detected in Australia in 2017 in Western Australia. This pest can cause significant losses in host crops and is considered to be a major biosecurity threat.
This exotic pest causes a disease called Psyllid Yellows and has a wide host range including tomatoes, potatoes, capsicums, chillies, eggplants, tomarillos and sweet potatoes.
As backyard growers of these vegetables we need to be informed and if there is any suspicion that our vegetables have this psyllid there is a Exotic Plant Pest Hotline number in the following PDF from IPM Technologies Pty Ltd.
This PDF has good images for identification purposes and also other critters that have a similar appearance.
