Monitoreo de las especies y hospederos alternativos de los géneros Anastrepha y Ceratitis en los cantones de Paute, Guachapala y el Pan de la provincia del Azuay

Abstract

This study was conducted in three cantons the province of Azuay, the procedure used was monitoring populations through McPhail type traps and Jackson, using as an attractant baited with hydrolyzed protein (2 liters of hydrolyzed protein, 500 grams of borax and graduated to 5 liters of water) using 250 cc per trap, and located in the middle of fruit trees assessed. In each canton were defined different fruit growing areas, orchards were selected, in which, they were placed jointly, a trap Jackson and a trap McPhail. Data collection was performed every seven days, to keep track of the population and identification of the genera and species of flies. In the cantons of Paute, Guachapala and the Pan, they registered the following species: Anastrepha fraterculus Wiedemann, Anastrepha distincta Stone, Anastrepha striata Schiner, Anastrepha grandis Macquart y Anastrepha obliqua Macquart. Anastrepha fraterculus Wiedemann was the most abundant in the canton Paute, Guachapala and the Pan, representing the 90.1%, 80.2% and 0.05% respectively. It wasn't found Ceratitis capitata Wied in canton the Pan. While that the genera of Anastrepha obliqua Macquart, Anastrepha striata Schiner y Anastrepha grandis Macquart, during all the monitoring study, were found a minimum population, that it represents 0.01% and 0.05% respectively. The hosts plants species determined, corresponded to guayaba (Psidium guajava L) specie of the Myrtaceae family, chirimoya (Annona cherimola Mill) of the Annonaceae family, pear (Pyrus communis L) of the Rosaceae family, peach (Prunus pérsica L) of the Rosaceae family, and guaba (Inga feuillei DC) of the Fabaceae family. The high populations of fruit flies captured in certain months coincide with the presence of host fruit in the countryside.
