Functional anatomy of the egg and the nymphal morphology of the teak tingid:Pontanm pueritis Drake and Poor (Heteroptera: Tingidae)

Abstract

The functional anatomy of the egg and the nymphal morphology of the teak tingid, Pontanus puerilis Drake and Poor have been described. The outer surface of the exochorionic collar presents a series of serrations which serve to grip the plant tissue firmly. The principal and accessory aeropyles with their extension canals and the so-called ••micro pyles " all serve the purpose of respiration. The length of the column varies in accordance with the length of the exochorionic collar and on that basis two types of eggs of P. puerilis have been recognised, viz., short operculate eggs that are deposited during the months of August-October and long operculate eggs, deposited during February, Total cessation of growth of the marginal tubercle of the metathorax ; translocation of the meso and meta thoracic and 2nd abdominal tubercles on to the wing pads and the disappearance of the 3rd abdominal marginal tubercles in the 5th instar nymph are significant features.

“…A atuação de parasitóides, ainda não foi constatada para essa espécie de inseto no Brasil, mas existem registros como os de Livingstone (1977) que observou na Índia, ovos de tingídeos parasitados por Trichogramma e Anagrus spp. No trabalho de Yacoob et al (1983) foram mencionados dois mimarídeos e três tricogramatídeos parasitando cerca de 20 tingídeos, sendo esses resultados confirmados posteriormente por Livingstone et al (1985) e Livingstone & Yacoob (1986).…”
