MORPHOLOGICAL CHARACTERIZATION OF THE MALE AND THE FIRST STAGE NYMPH OF PSEUDOCOCCUS CRIBATA (HEMIPTERA: PSEUDOCOCCIDAE) AND COMPARISON WITH OTHER PSEUDOCOCCIDS OF THE VID

Abstract

Pseudococcus cribata González, 2011 is distributed in Chile from Valparaíso to Biobío and their hosts are Vitis uinifera, Púnica granatum , Vaccinium sp, and Conuoluulus aruensis. Despite being a
species whose female was described recently, is established in the barracks of table grape production in Región VI- The aim of the study is to contribute to the knowledge of Pseudococcidae of Chile, characterized morphologically the adult male and the first instar nymph of P. cribata and comparing with other mealybugs developed in table grape, for which microscopic slides were prepared for each stage of development mentioned of P. cribata, P. uiburni (Signoret) and P. longispinus (Targioni Tozzetti). On the observations of these differences were detected in the adult male P. cribata with other species, like lack of sclerotic regions heavily in the chest and form the third antenito. As for the first instar nymph inelude overall body shape and the caudal end. The results show that although the morphological study of males and nymphs Pseudococcidae is still incipient, its development provides utility for species identification and subsequent management of pests.
