RESUMO

Agonossoma flavolineatum (Hemiptera, Scutellerinae), is a polychromatic and phytophagous specie, whose females show three distinct phenotypes, and only one of them is similar to that of the male. These differentiation on color among the individuaIs, are analogous to other species of the same genus resulting in problems for classification and identification. A revision of the genus was made in order to clarify the species denomination, characterizing them throw the coloration patterns, and throw some other structures like antennae and sternites. In the specific case of A. flavolineatum, the characterization was reforced by biological studies and species cariotype, which has 10 autosomes and a par of sexuaI chromosomes, being the male the heterogametic XY sex. How lt s usual to happen with several pentatomides, these chromosomes are of the type that doesn t present a localized centromer. According to the utilized criteria, 4 species were proposed for the genus: A. flavolineatum, A. trilineatum, A. bicolor, and A. dohrni. The biological studies of A. flavolineatum showed that males couple with the different female patterns, having in all cases, fertile offspring. Under monthly temperature and relative air humidity means that change between ?18,6 DEGREES?C and ?27,4 DEGREES?C, and 57,7% and 70,8% respectIvely, the medium duration, 10 days more or less the standard deviation of the female life cycles were found to be 156,9 ?+ OU ?? 10,74, and the males 166,08 ?+ OU ?? 10,62 days, with intervals of 59 to 392 days and 91 to 354 days, respectively. ...Note: The complete abstract is available with the full electronic digital thesis or dissertations
