Evaluation of traps with bait for the capture of diptera

Abstract

Throughout history and evolution, insects of genus diptera have had close relationship with human activities and environment. It is one of the most extensive and diverse taxonomic groups in forms, functions and relationship with humans. This research aims to describe the taxonomic and ecological diversity of diptera identified in the sanitary landfill of the city of Bluefields. To evaluate the effectiveness to capture these insects, different makes of traps were used. The location of the project was the municipal sanitary landfill of Bluefields. We evaluated nine traps using bait with twenty repetitions each. We gathered daily samples for five days, with intervals of 24 hours. Comparisons were made between the treatments and species captured identifying non-normal distribution of the data. The statistical asymptotic significance for each variable was evaluated by the nonparametric test of Kruskal-Wallis and Kolmogórov-Smirnov. The placement of traps with different attractants in the municipal sanitary landfill of Bluefields allowed the identification of the species Musca domestica, Pepsis sp. Germanic Vespula, Chironomus plumosus, Aedes aegypti, Ceratitis capitata, Hermetia illucens and Agapostemon sp. Out of all the evaluated traps, trap number one using honey as bait got the greatest number of individual captures of both sexes, greater durability over time, richer index of biodiversity and similarity in time; all these parameters with statistical difference with respect to the other traps. Out of these species predators, parasitoids and opportunistic insects have been identified.
