Abstract

The enhancement of pest control through the conservation of natural enemies in agricultural fields is called conservation biological control. One of the strategies used on this system is to introduce or manage plants that can provide food for natural enemies. We assessed the effect of feeding resources on the fitness of a coffee leaf miner parasitoid, Proacrias coffeae Ihering (Hymenoptera: Eulophidae), by evaluating the effect of different nectar resources on the survival of P. coffeae . To do so we used three flowering plants: Bidens pilosa , Galinsoga parviflora, and Varronia curassavica , and the leguminous shrub, Senna cernua Balb. H.S. Irwin & Barneby which produces extrafloral nectar. When feeding on the floral nectar of V. curassavica and on the extrafloral nectar of S. cernua the parasitoids increased their survival, however, no significant differences were found when feeding on B. pilosa and G. parviflora . We evaluated the effect of extrafloral nectar of S. cernua on the egg load of P. coffeae and found an increase in their egg load when exposed to the extrafloral nectar and with increasing age. Our results show the potential of V. curassavica and S. cernua as nutritional resources to enhance the fitness of the parasitoid P. coffeae, by increasing their survival. Based on the research study, it is evident that the introduction of feeding resources for P. coffeae in the coffee agroecosystem will increase their fitness as a potential biocontrol agent by enhancing their survival and reproductive potential.
