Adults parasitoid feed on sugar rich sources such as floral nectar and honeydew sources and these can increase the potential for control of these natural enemies. Palmistichus elaeisis Delvare & LaSalle (Hymenoptera: Eulophidae) is a generalist endoparasitoid of Lepidoptera and Coleoptera pests. The reproductive parameters and longevity of P. elaeisis were evaluated using different sources of carbohydrate (fructose, glucose, sucrose, mixture of sucrose + glucose + fructose, and honey,) all these sugars were 99% pure and 1M concentration solutions were made with distilled water. The carbohydrate source did not affect the life cycle and progeny emerged, but affected the sex ratio of P. elaeisis. However, this parasitoid showed a higher proportion of females than males with all diets, which is desirable in biological control programs. The lowest values of parasitism (85%) mixture with honey and fructose + sucrose + glucose did not affect the percentage of emergence of P. elaeisis. The longevity of males was similar with all the sources, the female longevity with the sources of fructose, sucrose, glucose and fructose + sucrose + glucose were significantly higher than honey. These carbohydrate sources can be used in mass rearing of the parasitoid, being the most appropriate source financially honey. The longevity of P. elaeisis females was affected by the carbohydrate source showing that honey, though it can be used for mass rearing for increased longevity is required the availability of sources such as fructose, sucrose, glucose and fructose + glucose + sucrose.
