Ten nests of Sceliphron fistularium were obtained in two sites: Panama Oeste province, shores of Gatun Lake, Jungle Land Panama, and the province of Panama in the building of the School of Biology, University of Panama, Central Campus. The complete nests consisted of 3 to 14 cells, making a total of approximately 79 cells among the 10 nests. The nests were tubular in shape with the upper end oval and the basal end with a slight decrease in acute form, arranged side by side along a horizontal axis, and were found attached to different artifacts: a telephone wire (Campus Central University of Panama, n = 2); in three plastic chairs and two in wooden ceiling beams, installations of a floating boat (Gatun Lake, Jungle Land Panama, chairs n = 5 and wood n = 3). The number of cells per nest ranged from 3 to 14, their length ranged from 32.5 to 38.6 mm and their diameter from 15.3 (anterior) to...

As far as we can increase the knowledge about parasitoids or any natural enemy of plagues, contributions are relevant. These groups of insects have an important value, since the help to maintain insect population equilibrium and specially insects that are also plagues in different terrestrial ecosystems. The aim of this work is to report for the first time the parasitoid Palmistichus elaeisis (Hymenoptera: Eulophidae) in pupae of the butterfly Quadrus cerialis (Lepidoptera: Hesperiidae) over seedlings of Piper tuberculatum. These biological observations were made in the Biological Reserve Dr. Rodrigo Tarté, City of Knowledge, Panama province. Six seedlings of Piper reticulatum (Piperaceae); with a mean height of 0.5-1.0 meters, it was located in an open area on the sides of the path, asphalt road inside the Reserve (City of Knowledge). The material was collected and placed in insect hat...

Anastrepha obliqua (Macquart, 1835) (Diptera: Tephritidae), known as the West Indian fruit fly, is a widely distributed species in America. Due to its polyphagous capacity, this insect is of great economic importance, which is studied based on its distribution, forms of management and control. Doryctobracon areolatus (Szépligeti, 1911) (Hymenoptera: Braconidae), a native species, solitary endoparasitoid, koinobiont, has a wide distribution in the Neotropics and subtropics, and due to its capacity as a parasitoid of the genus Anastrepha is a potential candidate for the natural control of this pest. The species Psidium guajava L., native to Mexico, is a fruit with high nutritional value and has great relevance from the commercial perspective. In Panama, the information related to the Parasitoid-Anastrepha-Fruit relationship in this species is limited, so it is of high value to establish r...
