Preferencia cromática de la mosca de la fruta en trampas esféricas colocadas en un huerto de manzana (Malus domestica Borkh) cv. Anna en Guachapala-Azuay

Abstract

The fruit fly is one of the most important quarantine pests in the world affecting various fruit crops such as apple. The insects have the ability to recognize and be attracted to different colors and shapes thanks to photoreceptors in their eyes. In this study, we sought to determine the influence of color and trap height on the sex and species preference of the two fruit fly species present in the study area (Ceratitis capitata, Anastrepha fraterculus). This study used red, yellow, orange, green and white spherical traps placed in the upper and lower thirds of the apple trees. The green traps captured the most fruit flies with 43.4%. Treatment T8 (Green, upper third) captured the most specimens of female Ceratitis capitata with 26.42% of flies captured. The percentage of captured fruit flies of the species Anastrepha fraterculus with 17% was low compared to Ceratitis capitata. In terms of height, it was observed that 77.4% of the fruit flies captured of the two species were in the upper third
