Using artificial solid diets, experiments were performed with Anastrepha obliqua (Macquart, 1835) wild females in order to verify the influence of different quantities of brewer yeast on the performance and compensation behavior to unbalanced diets ingestion. The observed parameters were egg production, ingestion, diet efficiency and survival in the reproductive phase. Results indicated that there was no compensatory ingestion to different quantities of yeast and that the diet with 12.5g of yeast provided the best performance. The absence of compensatory ingestion is discussed based on the yeast phagostimulation and on the costs involved in solid diets ingestion. The relation between the analyzed parameters and the protein quantities in the diet were... |

The minimum protein amount that Anastrepha obliqua MacQuart can detect in its alimentary source is variable, though the causes of such variation are not very well known. In this study, the authors tested whether the sexual partners nutritional condition and presence devoid of direct contact alter the A. obliqua protein discrimination threshold. Male and female insects were assigned to groups as follows: (i) newly emerged, (ii) deprived of protein source (yeast) during 18 days, (iii) non-yeast-deprived during 18 days, (iv) yeast-deprived in the presence of equally yeast-deprived sexual partners, (v) yeast-deprived in the presence of non-yeast-deprived partners, (vi) non-yeast-deprived with yeast-deprived partners and (vii) non-yeast-deprived with... |
