A morphological and systematic study of the first and second instars of the Kermesidae in the Nearctic region (Homoptera: Coccoidea)
Abstract
dc:description.abstractThe Cocco idea or scale insects are among the most important pests of sylvicultural, ornamental, agricultural and greenhouse plantings throughout the world. There are 21 families comprising 6,000 species. Direct injury occurs from the withdrawal of sap while feeding and from the production of galls. Some scale insects are host specific while others are polyphagous. They feed on many different parts of plants including the roots, trunk, stems, leaves, buds and fruit.
