Α-COPAENE AS POSSILBLE CAIROMONE FROM BANANA PSEUDOSTEM AS AN ATTTACTION COMPOUND OF Cosmopolites sordidus

Abstract

ABSTRACT Cosmopolites sordidus (Coleoptera: Curculionidae), popularly known as banana borer, is considered a key pest of banana tree (Musa spp.), and occurs in all regions of Brazil. Damage can occur in both pseudostem and rhizome of the plant, reducing production by up to 90%. For their control, the use of insecticides and attractive bait from pseudostem pieces is indicated, however, these methods have shown limited efficacy. The use of semiochemicals has shown to be an efficient way to control pest species within Integrated Pest Management (IPM). The volatiles were captured in the field at Fazenda Bonsucesso, in the city of Coruripe / AL, and the prosprection of volatile organic compounds from parts of the banana plant was performed by gas chromatography and mass spectrometry, performed at the Natural Resources Research Laboratory - Institute of Chemistry and Biotechnology - IQB, at Federal University of Alagoas - UFAL - Campus A.C. Simões - Maceió / AL. α-copaene was identified. Studies indicate that α-copaene has been effective as an attractive to some beetles and other insects, either alone or in a mixture. Therefore, this paper aims to identify in the literature the use of α-copaene as an alternative for monitoring and / or control of C. sordidus.
