Recently, many tomato gardeners in New Zealand also disappointing because of miserable their, and it is possible that the pest called psyllid is the caused. MAF Biosecurity New Zealand says there is been so much interest among home gardeners in the damage caused by the psyllid that it has distributed a fact sheet about the pest to more than 300 garden centres nationwide.

The cause of psyllid in tomatoes can cause small and poor quality fruits even they can prevent fruit forming. In potatoes they cause almost a same symptom. They make the number and size of tubers smaller than the uninfected one. Harvested tubers often sprout prematurely, Plant and Food Research says, and after a while infected potato plants can look scorched and collapse prematurely. Beside tomato and potato, psyllid also can infected capsicums, tamarillo and cape gooseberry trees.

For many time, psyllid found in United States, northern Mexico and southern Canada, and now also found in New Zealand and has been found in both outdor and greenhouse crops. Psyllid live underside of the leaves. In adult form they are about the size of adult aphids and look like miniature cicadas. They feed like aphids and transmit a bacterial pathogen called Liberibacter which infect the plants. The female psyllid known can lay up to 510 eggs during their lifetime. The eggs are oval shape with orage to yellow color. They are attached to leaves by a stalk.

They remain nymps for between 12 and 21 days and then grow to two millimeters in length and begin to feeds on the underside of leaves. Adult psyllid are 3-4 millimeters in length with long and clear wings.

They cause the damage in plant by suck plant sap and infect the plant with bacterial pathogen. These stage possibly causing the leaves become discolored and the plant to become stunted, with upturned leaf edges yellowing or showing a purple color.
