Résumé : Within the genus Diatraea, studies of alternate host plants were mainly conducted on Diatraea saccharalis (Fab.). Such information doesn't exist for Diatraea tabernella Dyar. Therefore, the objective of this study was to determine the alternative host plants of D. tabernella in sugarcane plantations in Panama. From January 2016 to February 2017, a general inventory of alternate host plants was conducted in the sugarcane field and then plants were sampled among the most frequent 9 species found (Poaceae (8) and Cyperaceae (1)) in four areas the sugarcane field (near water source (Z1), within field (Z2), near mangrove (Z3) and field edge (Z4)). The species with the highest % borer infestation during the sugarcane growth period were Sorghum halepense (L.) Pers. (7.2%), Echinochloa colonum (L.) Link (6.4%) and Eleusine indica (L.) Gaertn. (5.8%). During the sugarcane harvest the species with the highest percentage of infested stems were Eleusine indica (L.) Gaertn. (21.6%), Dactyloctenium aegyptium (L.) Beauv. (17.1%) and Cenchrus echinatus (L.) (9.2%). On these host plants, species control measures may be applied to reduce stemborer populations.
