Resumo: | Few works have studied in detail the types of nutrients associated to hosts which are attractive to females of Anastrepha obliqua (Macquart) and influence the choice of the oviposition site. The relationship of the males in the physiology and in the behavior of those females has also been scarcely studied and some ecological relationships seem to be quite important for the knowledge of this species' biology. Our objective in this study was to evaluate the discriminatory behavior of A. obliqua between oviposition sites containing different nutrients. The presence of the male and the nutritional status of the female were also considered in this work. Two experiments were developed: in the first, the preference of A. obliqua females between artificial oviposition substrates was evaluated; in the second, females were submitted to two types of artificial oviposition substrates in the presence and in the absence of males and were fed either on a poor diet or on an adequate diet concerning sucrose concentration. In the first experiment, A. obliqua showed higher preference for substrates containing brewer's yeast and sucrose. Substrate containing only yeast was the second most accepted. Offspring development and adult feeding may have determined the choice for the substrate containing brewer's yeast and sucrose. In addition, the presence of protein in the brewer's yeast may indicate nutritional quality to the females in a more accurate way than the sucrose. In the second experiment, the brewer's yeast was the most accepted by the females. The male absence was also an important factor in the selection of hosts and in the egg production of A. obliqua. |

Few works have studied in detail the types of nutrients associated to hosts which are attractive to females of Anastrepha obliqua (Macquart) and influence the choice of the oviposition site. The relationship of the males in the physiology and in the behavior of those females has also been scarcely studied and some ecological relationships seem to be quite important for the knowledge of this species' biology. Our objective in this study was to evaluate the discriminatory behavior of A. obliqua between oviposition sites containing different nutrients. The presence of the male and the nutritional status of the female were also considered in this work. Two experiments were developed: in the first, the preference of A. obliqua females between artificial oviposition substrates was evaluated; in the second, females were submitted to two types of artificial oviposition substrates in the presence and in the absence of males and were fed either on a poor diet or on an adequate diet concerning sucrose concentration. In the first experiment, A. obliqua showed higher preference for substrates containing brewer's yeast and sucrose. Substrate containing only yeast was the second most accepted. Offspring development and adult feeding may have determined the choice for the substrate containing brewer's yeast and sucrose. In addition, the presence of protein in the brewer's yeast may indicate nutritional quality to the females in a more accurate way than the sucrose. In the second experiment, the brewer's yeast was the most accepted by the females. The male absence was also an important factor in the selection of hosts and in the egg production of A. obliqua. |
