Melaço de cana-de-açúcar como atrativo alimentar para coleobrocas em bananeiras da cultivar Brs Vitória

Abstract

In Brazil, banana (Musa spp.) is a product of strong acceptance and high consumption. The Northeast region stands out as a major banana producer in the country and the state of Paraíba is an important producer, especially for the micro-region of Brejo, which contributes greatly to the production of the State. The cultivar BRS Vitória can be an alternative for banana growers, being essential to study the conditions of cultivation in the municipality of Bananeiras. The objective of this work was to evaluate the incidence of Cosmopolites sordidus and Metamasius spp. using sugarcane molasses as a food attractant. The research was carried out in a 3.5ha orchard of banana trees of cv. BRS Vitória, located at the Federal University of Paraíba CCHSA/UFPB. Four plots with an area of 100 m² were demarcated. Then, the “tile type” traps were made using pseudostem of banana trees that had already produced, receiving 25 ml of the food attractant based on sugarcane molasses diluted at 10% on the cut face. Four traps were distributed in each plot, two containing the food attractant and two untreated controls. After receiving the treatment, the traps were distributed next to the banana clumps, with the cut part facing down, being evaluated every 7 days to remove and carry out the counting and identification of the insects, the traps being replaced by new ones every 14 days. days. It was possible to conclude that the use of sugarcane molasses showed high efficiency in capturing C. sordidus and Metamasius spp; the infestation of C. sordidus is well above the level of economic damage, indicating the need for control; it is necessary to keep monitoring and attention to the levels of Metamasius spp infestation in banana cv. Victory in Brejo region.
