Control biológico de picudo (Cosmopolites sordidus) con Beauveria bassiana con cuatro tipos de trampa.

Abstract

The objective of this research was to determine the biological control of the black boll weevil (Cosmopolites sordidus) with four types of traps with Beauveria bassiana in banana Barraganete, for this purpose 60 experimental units were evaluated arranged in a complete randomized design with 5 treatments: T1 (Control), T2 (Ramp), T3 (Caneca), T4 (Wedge type), T5 (Cormo en V); the number of weevils captured, number of black and striped weevils captured, capture efficiency and production costs were measured. The results showed that the highest number of captured adults of the black weevil (Cosmopolites sordidus) in the Barraganete banana crop was obtained with the wedge trap with 15,33 individuals per week, being superior to the other treatments evaluated. The wedge trap proved to be the most efficient in capturing adults of the black weevil (Cosmopolites sordidus) in the barraganete banana crop, with 39.56%. The production cost of the wedge trap was the most economical with a value of $ 0.61 USD.
