Potato psyllid

Posted on by

Scientific name: Bactericera cockerelli

Size: 1,9 mm

Origin: North America

Name (ES): Pulgón saltador de la patata y el tomate

Description:

This pest is limited to solanaceous crops with a preference for tomato, potato, aubergine and pepper.

A vector for ‘Candidatus liberibacter solanacearum’ bacteria, they acquire and propagate the pathogen by feeding on infected plants. It is the causal agent of ‘zebra Chip’ disease, causing brown decolouration of the vascular ring in fruit and stripes in potatoes. Damage is also caused to the aerial parts of plants, through atrophy or abnormal growth, chlorosis or purple leaves, inflated knots, aerial tubercles etc.

Present in the Balearic Islands since 2018

As its name suggests, the boxwood caterpillar feeds on the boxwood, specifically its leaves. Partial or total defoliation of the hosts may represent a danger for plant survival. The Balearic Islands are home to two species of this plant: Buxus sempervirens and B. balearica, both endemic species to the Balearic Islands and classified for special protection.
