Interpretive Summary:

Technical Abstract: During 2015 to 2017, a study was carried out to determine species of sugarcane stem borers for panela present in La Hoya del Río Suárez (Boyacá and Santander, Colombia). Monthly, nine farms distributed in three areas were visited in which stems with dead heart symptom were collected, through a sampling effort of two man-hours. In addition to Diatraea spp. and Blastobasis sp. larvae, 6.8% individuals of a new species were found: Eoreuma insuastii, the striped borer of panela cane that exerts damage by piercing young stems and feeding inside them. Dr. Alma Solis, Crambidae specialist of the Smithsonian Museum, made her determination. The larva has a transverse brown plate on mesothorax, longitudinally on the abdomen it exhibits four pink stripes alternated by cream-colored stripes. The eruciform larvae, measure about 1 mm recently emerged and reach about 20 mm when developing. The larvae weave a layer of thin and resistant silk where they pupate. The light brown pupa lacks cephalic or lateral protrusions and is 15 mm long. The adult is straw-colored with elongated labial palps and 17 mm in length. Feeding with artificial diet for D. saccharalis, the larval stage lasts about 60 days, 12 the pupal stage and the adults survived for five days. In laboratory, cream-colored ovoid eggs less than 1 mm in diameter were obtained, laid singly by the female. Some specimens of E. insuastii were found parasitized by Billaea claripalpis, Genea jaynesi (Diptera: Tachinidae), Cotesia flavipes and Alabagrus stigma (Hymenoptera: Braconidae).
