Adult thrips are about 1 - 1.5mm in size and dark colored with dark legs. Females are slightly larger than males. Their body is slim. The wing base is pointed and white. The rest of the wings is transparent with a darker band in the middle. Distal part of the legs has light color. Eggs are laid in the plant tissue and are hardly visible from the outside. Larvae are translucent to white - yellow. Pupae are white and thicker than the larvae.
Damage and distribution in the crop:
The thrips usually sit on the leaves and flowers, sometimes in or on the fruit. They have a preference for the underside of the leaves, but especially the adults also move to the top of the plant and occasionally can be found there. The thrips are mainly found low in the crop. Pupation occurs on the leaves. The thrips puncture leaf cells and suck from plant sap, thus emptying the plant cells. The result is small and large grayish spots on the leaves. On the leaves they deposit small dark droplets of excrements.
