Bioatividade do resíduo de sisal (Agave sisalana Perrine ex Engelm) sobre Ceratitis capitata (Wiedemann, 1824) (Diptera: Tephritidae) e Diachasmimorpha longicaudata (Ashmead, 1905) (Hymenoptera: Braconidae)

Abstract

Ceratitis capitata, considered one of the most destructive pests worldwide for producing fruits, is conventionally controlled with synthetic chemicals products. The use of botanical extracts is an alternative method to control of these pests. The sisal is a plant native to the arid and tropical regions of the Western Hemisphere, rich in secondary metabolites, which has adapted very well to the Northeast region. Today is produced in large scale mainly in the state of Bahia. The objective of this study was to evaluate the potential attraction of botanical extracts from sisal waste on oviposition of C. capitata, and on the selectivity the beneficial organism Diachasmimorpha longicaudata. The aqueous extract of dry waste at 5% showed the greatest attractive potential on C. capitata. All extracts at different concentrations negatively interfered in the emergence rate of C. capitata adults demonstrating insecticidal effect. The aqueous extract of dry waste at 5% interfered in locating and posture rate of natural enemy D. longicaudata and possibly in the reduction the rate of parasitism.
