Abstract

The Reduviidae includes predatory bugs such as Arilus gallus (Stål, 1872), which contribute to the natural control of pests in productive agroecosystems and to the ecological balance in protected areas. These insects have natural enemies, such as the egg parasitoid Neorileya albipes Girault, 1913 (Hymenoptera: Eurytomidae). The purpose of this study was to report the parasitoid species of A. gallus eggs found in the Fortuna Forest Reserve, Chiriquí, Panama. For this, a group of 125 A. gallus eggs was collected, attached to a dry leaf that covered an internode of gutter straw (Saccharum spontaneum L.), on the edge of the road within the Reserve. 25 samplings were carried out along seven (7) transects of 1 kilometre each; on a 7-kilometre trail. Oviposition time at the site (9:20 am – 2:30 pm) of the parasitoid wasp on A. gallus eggs was observed and recorded. In addition, behavioral, biological and ecological observations of the parasitoid were made when it was parasitizing. The eggs were transferred to the laboratory, and it was possible to obtain two adult parasitoid wasps; confirming the identification of N. albipes. Each wasp hatched from an A. gallus egg, 38 days after oviposition. Neither nymph hatching of A. gallus nor parasitoids were obtained from the other 123 eggs. This finding confirms the importance of knowing the trophic interactions both in agroecosystems and in natural vegetation, even more so when considering the implementation of Integrated Pest Management.
