Identification and damage
Coccus hesperidum is a widely spread polyphagous species; it is also present in greenhouses on ornamental plants and frequently attacks citrus fruits. The adult female (about 3.5-4 mm long) is oval in shape, with a depressed body and a yellow-brown color. Juvenile forms are lighter in color than adult females. Coccus hesperidum preferably lives on the twigs and on the underside of the leaves, where it forms colonies along the ribs. The damage occurs on the leaves and is caused by trophic stings and honeydew production; the affected vegetation shows strong yellowing and is smeared with honeydew, on which fumaggini are formed; in case of massive attacks, severe phylloptosis can occur.
The phytophagous winters as a neanid and completes several generations a year.
