dc.description.abstractSugars are important food sources required by adult parasitoid species to enhance their survival, fecundity and fitness. The beneficial capacity of Psyttalia concolor Szépligeti, as a biological control agent of different fruit fly pest species, is expected to increase when different sugar food sources are supplied. The objective of this study was to test the effect of seven sugars (glucose, fructose, sucrose, trehalose, melibiose, melezitose and sorbitol) on the longevity and parasitism capacity of P. concolor. Moreover, we evaluated the effect of two types of honeydew excreted by hemipteran pests present in olive trees, Saissetia oleae Olivier (Coccidae) and Euphyllura olivina (Costa) (Psyllidae) on the longevity of the parasitoid. Our results show a positive effect of carbohydrate (single sugars and honeydew) consumption on parasitoid survival. Female longevity increased when fed on sorbitol and melibiose, while males benefited from feeding on glucose and fructose, suggesting that hexose-nectars would benefit males. Sucrose increased the percentage of non-emerged hosts and parasitism rate while melezitose significantly decreased these percentages, compared to the other sugars offered. P. concolor benefited more from feeding on honeydew than on sugars, and this food item can represent an important source of energy for the parasitoid. This result indicates the importance of specific nutrients for promoting the action of P. concolor against pestspt_PT
