The research aimed to identify the fruit flies species, hosts, and their geographical distribution in the area of influence of the Carrizal-Chone water system (Bolívar, Chone, Tosagua y Junín). Two monitoring routes were implemented in the studying area, 24 home-made traps were evaluated, using passion fruit fermented extract as a bait. Traps were collected every fifteen days, preserving the “fruit flies” in a jar with alcohol and changing the bait at a time. Simultaneously, fruits with flies evidence were collected. Samples were processed in the entomology laboratories of the Agricultural Polytechnic of Manabí and the National Institute of Agricultural Research. From the data, it was possible to identify species, hosts, distribution, population dynamics, and index fly per trap per day (MTD). Six species were identified of which Anastrepha fraterculus y Anastrepha obliqua belong to the widest distribution. The fruits collected were guava, mombin, mango, araza, sapote, star fruit, and mamey sapote. It was determined that availability and plenty of fruit hosts and native species are important factors that influence the fluctuation and temporality of “fruit flies” populations. |
