Novas espécies e novo gênero de Eriophyidae (Acari :Prostigmata) associados a fruteiras tropicais e Caesalpiniaceae no Estado de Pernambuco e observações biológicas de Aceria n. sp. em Caesalpinia echinata La

Abstract

A new genus and a new species of Phyllocoptini Eriophyidae, Shrekin graviolae Britto and Navia, from Annona muricata L., and a Nothopodini Eriophyidae, Cosella decorata Britto and Navia, from the Malpighia emarginata Sess and Moc. were described from females and males. Furthermore, Aceria n.sp., an Aceriini Eriophyidae from Caesalpinia echinata Lam. with a complex life cycle is described. Observations on the biology of the last species are presented. Whole life cycle develops under patches of webbings built by the deutogyne on the surface of the leaves. The immature stages development for deutogynes lasts 16-17 days, at 26°C, 12h photophase and 60% relative humidity. Periods of egg incubation, larval and nymphal stages were 5-6, 6-7 and 5-6 days, respectively. Individual "nest" sizes ranged from 0.07-3.2 mm2 and their relative numbers of females was always 75-76% of deutogynes and 24-25% of protogynes. This is the first case of a deuterogynous eriophyoid mite with two forms of males from the tropics.
