ValidaÇão da armadilha adultrap® para captura de dípteros muscoides

Abstract

ResumoO potencial da armadilha adultrap® para captura de dípteros muscoides foi avaliado por comparação com a armadilha descrita por Ferreira (1978) e adaptada por Fraga e d' Almeida (2005). Iscas de sardinha foram utilizadas em ambas as armadilhas. O teste de Wilcoxon para duas amostras não pareadas foi empregado para comparação das armadilhas. Capturou-se um total de 8.909 dípteros muscoides, sendo 57,51% desses pela adultrap®, mas sem diferença significativa (p = 0,147) entre as armadilhas. Do total de sarcofagídeos, califorídeos, muscídeos e de outras famílias de dípteros muscoides 79, 68, 29 e 31%, respectivamente, foram capturados pela adultrap® com diferença estatística (p = 0,002) entre as armadilhas apenas para a família Sarcophagidae. Os resultados da adultrap® foram similares ao modelo modificado por Fraga e d' Almeida (2005). Entretanto, adultrap® foi mais eficiente na captura de dípteros da família Sarcophagidae.Palavras-chave: Diptera, Sarcophagidae, Muscidae, Calliphoridae, moscas. AbstractThe potential of adultrap® for capture of muscoid dipterans was evaluated by comparison with the trap described by Ferreira (1978) and adapted by Fraga and d' Almeida (2005). Sardine baits were used in both traps. The Wilcoxon two-sample test was used for trap comparison. A total of 8,909 muscoid dipterans was caught, 57.51% of them by the adultrap®. However, there was no significant difference (p = 0.147) between trap efficiency. From the total of sarcophagids, calliphorids, muscids and other families of muscoid flies, 79, 68, 29 and 31% were caught by adultrap®, respectively. Statistical difference (p = 0.002) between traps was found only for Sarcophagidae. The results of adultrap® were similar to the model used by Fraga and d'Almeida (2005), thus validating its use for seasonal fluctuation studies of muscoid dipterans. However, adultrap® has the highest efficiency in capturing Sarcophagidae flies.

“…T raps constructed using metal receptacles have the advantage of being inexpensive and easy to construct. However, since these are constructed by the user, lack of standardization may occur and this can be considered to be a disadvantage (Souza et al, 2009). Among other disadvantages, the plastic collecting bag may collapse at times of rain or wind, and agglomeration may occur in association with the increased moisture levels produced through evaporation and transpiration of the bait, thereby damaging some specimens and making it difficult to identify them (Guimarães and Guimarães, 2003).…”
