ABSTRACT
The study of the species complex Anastrepha fraterculus (Af complex) in Brazil is especially important in a taxonomical, evolutionary and pest management context, because there are evidences that some of them may occur in sympatry. In this review, we analyzed the main results supporting evidences that three cryptic species occur in Brazil. The taxonomical and phylogenetic relationships based on eggshell morphology, adult morphometrics, as well as cytotaxonomy and genetic differentiations are discussed. We also review available information on sexual behavior including acoustic communication of males during courtship and sexual incompatibility; and chemical signals involved in the communication between sexes, with a special focus on sex pheromones. We examined the role of long- and short-range pheromones (male-produced volatiles and cuticular hydrocarbons, respectively), their implications in sexual isolation, and their possible use for chemotaxonomic differentiation of the putative species of the Af complex.
ABSTRACT
Neste trabalho estudou-se os seguintes aspectos da preferência de oviposição de ceratitis capitata, praga da fruticultura: verificação da influência do valor nutritivo e do sabor de dietas, qualidade nutricional de dois frutos; influência da alimentação das fêmeas e da experiência prévia destas. Os resultados indicaram que o sabor e mais importante para as escolhas que o valor nutritivo, não há influência da alimentação e há influência da experiência prévia (AU)
