RESUMO

Chelymorpha cribraria F. 1775. (Cassidinae, Chrysomelidae) is a polymorphic species in Campinas, state of São Paulo (Brazil). The different collos patterns of C. cribraria were described as different species by other authors. In the present study these species wee grouped as synonyms and their epithetum were used to assign the corresponding color patterns. The different forms of C. cribraria are given by the combination of the pronotum and elytra colorations. These caracters are genetically controlled by at least five genes and its alleles (maximun of theree). These genes are strongly linked, segregating as genic blocs. No case of recombination was observed. The population of C. cribraria has six genic blocs and their combinations produce 21 genotypes and 8 phenotypes. The inheritance of these caracters is not linked to sex and the mode of inheritance is mendellian. Except for the variegate pattern of pronotum, wich was considered to be one caracter in this genetic model of inheritance. The different patterns of C. cribraria are numbers of mimetic associations with othe Chrysomelidae ain Coccinelidae sympatric species. In the present study various experiments were realized to verify the unpalatability and mimicry of the beetle species, using spiders and birds as esperimental predators. ...Note: The complete abstract is available with the full electronic digital thesis or dissertations
