    Abstract

    Floral nectars, homopteran honeydews and honey are known to increase parasitoid longevity. However, these foods are composed of several sugars which may differentially affect longevity. We tested the effects of individual sugars and mixtures on the longevity of Bathyplectes curculionis Thomson (Hym., Ichenumonidae), a natural enemy of the alfalfa weevil. There was a significant difference in the longevity of female wasps on the various diets. Glucose or fructose alone appeared to have the most benefits while trehalose and melezitose were not as useful for increasing wasp longevity. Suitability of these sugars for provisioning food for parasitoids in the field is discussed.
