Palm thrips

Parthenothrips dracaenae
Appearance:

The body of adult thrips is light to dark brown in color. The adult thrips wings are light in color with a prominent dark lateral band in the middle and a less distinct dark lateral band further back on the wing. The transverse bands provide the thrips its name zebra trips. The antennae of the thrips are light in color. The larvae are somewhat transparent white.

Damage and distribution in the crop:

Zebra thrips feeds on the leaves. Adult thrips often reside on the upperside of the leaves while larvae are found mostly together in groups on the underside of the leaves. Both adults and young stages feed themselves by puncturing leaf cells and sucking them empty. This causes light gray, silvery patches on the leaves with small black dots, the excrement of the trips. The spots often contain empty skins of the young stages that remain after moulting. Zebra thrips is not known to transmit virus.
