SUMMARY:

The search for renewable energies has transformed the current agricultural scenario and, as a result, much emphasis is given to the sugarcane crop, which, in practically all its phenology, is infested by borers, which are key pests for the culture. Thus, researches that corroborate with varieties resistant to these insects become of fundamental importance for their management in production systems. The present study aims to characterize genotypes of the Saccharum spp. and biotic stresses caused by borers. Therefore, we evaluated the intensity of infestation of the giant borer Telchin licus (Drury, 1773) (Lepidoptera: Castniidae) in a commercial area in São Miguel dos Campos, AL during the 2021 and 2022 harvest, analyzing the total amount of internodes and the number of brocade internodes. The larval antiobiosis of D. saccharalis (Fab. 1794) (Lepidoptera: Crambidae) was evaluated from an experimental planting of the genotypes in a greenhouse at the Research Execution Unit of Embrapa Tabuleiros Costeiros (UEP de Rio Largo, AL). In the laboratory, two experiments were carried out: the biology and construction of the fertility life table of D. saccharalis, fed with an artificial diet, produced from the studied sugarcane genotypes and the biology of its parasitoid Cotesia flavipes Cameron (Hymenoptera: Braconnidae), from the parasitism of caterpillars fed the aforementioned diets.
