EVALUATION OF THE METHODS FOR MONITORING POPULATIONS OF ARTHROPODS ON POULTRY FARMS IN PELOTAS, RIO GRANDE DO SUL, BRAZIL

ABSTRACT

The community of arthropods found on farms is currently of great medical and veterinary concern, because they are vectors of various diseases, causing sanitary and economic problems. In this study, arthropod monitoring methods were comparatively evaluated on a poultry farm. The evaluations were made over a period of 12 months, in a hen house of the Conjunto Agrotécnico Visconde da Graça, in Pelotas, RS, Brazil, using “tube-type” or Arends traps and “sandwich-type” traps. The “sandwich-type” trap proved more efficient in the capture of the arthropods, the species captured being Alphitobius diaperinus (Coleoptera), Carcinops troglodytes (Coleoptera), Euspilotus rubriculus (Coleoptera), Gnathocerus cornutus (Coleoptera), Mezium americanum (Coleoptera), Somotrichus unifasciatus (Coleoptera), Euborellia annulipes (Dermaptera), Drosophila repleta (Diptera) and Withius piger (Pseudoscorpionida).
