Ecologia e comportamento de Pachycoris torridus (Hemiptera: Scutelleridae): nova planta hospedeira, polimorfismo quanto à coloração, cuidados maternais e parasitismo
The frequency of the different phenotypes, maternal care and parasitism in Pachycoris torridus (Hemiptera: Scutelleridae) on a new host plant, Cnidoscolus pubescens (Euphorbiaceae), was studied in an area of Atlantic Forest, in southeastern Brazil. Seven different phenotypes, three not previously recorded, were found among 54 adults. Females were only observed guarding eggs and first-instar nymphs. Unidentified species of Trichogrammatidae (Hymenoptera) and Spalangia sp. (Hymenoptera: Pteromalidae) were found parasitizing, eggs and nymphs of P. torridus, respectively.
Keywords: Cnidoscolus pubescens, maternal care, parasitism, phenotypic variation.
