Demography and esterase polymorphism of brazilian populations of Zaprionus indianus (Diptera: Drosophilidae) from the Brazilian Cerrado localities

Zaprionus indianus (fig fly) is a drosophilid of African origin that was recorded in Brazilian territory 1999, quickly dispersing throughout the country, causing impacts on fig culture, and becoming one dominant Drosophilidae species Cerrado biome. Due to fact it an invasive potential pest fruit cultivars, essential monitor variations populations this aiming verify its genetic demographic structure possible community. The demography data obtained from Est3 polymorphism fly have been evaluated six sampled during dry season. Multivariate analyses PCA, UPGMA landscape genetics were performed. results indicated variation populations, presence two alleles (Est31 Est34) all them, higher isolation degree Guaíra (SP) population. Thus, colonizer Cerrado, polymorphisms locus are appropriate marker investigate bioinvasion process.
