| Content Stem borers, Diatraea spp., are considered one of the most economically important pests in sugarcane cultivation in the American countries. In the Cauca River Valley, the species reported so far are: D. saccharalis y D.indigenella, and it is estimated that the damage they cause to the crop reduces production, on average, by 143 kilos of sugar per hectare for each percentage unit of damage, including the reduction in tonnage in the field and the recovery of sugar in the factory (Gómez et al., 2009). In October 2012, larvae of the Diatraea that apparently did not match the characteristics of D. saccharalis y D.indigenella. Observation of the morphology of the different life stages (larva, pupa and adult) of the collected individuals and confirmation by Dr. Alama Solís, a taxonomist specializing in this group of insects, allowed the larvae to be identified as belonging to the species Diatraea tavern Dyar, which is the first record of this species attacking sugar cane in the Cauca River valley. |
