[Comparison of different sampling traps for Dermanyssus gallinae (Acari: Dermanyssidae) (de Geer, 1778)].

This work aims to compare the performance of corrugated paper and "taquaril" bamboo (Phyllostachys sp.) straw traps for collecting (in sampling) Dermanyssus gallinae in a metal cages battery laying hens. The presence of eggs in the two trap models were compared using a Qui-square test and a proportion confidence interval test. Total daily values of mobile instars gathered in each type of trap were compared using the Wilcoxon's test. The amount of traps containing eggs was not different in neither of the traps (p < 0,05). The number of mobile instars sampled at every two days per trap model was different (p </= 0,01). Counting in the corrugated paper traps showed a Gauss distribution histogram and was superior to the values of the bamboo straw traps.
