coloured pan-traps to sample Musca domestica

Samplings were performed at the caged-layer poultry facility called as Aviário Santo Antônio located at Nepomuceno city, Minas Gerais, Brazil. Four sets of pan-traps were randomly placed next to the to the cages of the poultry farm. Each set of plan-trap consisted of four subsets of plastic pots painted in white, yellow, red and blue colours, therefore, totalizing 16 samples in the field. Inside each pot was added 500ml of water with detergent and salt used to remove the surface tension of the water and to preserve the collected flies in the pots. The pots remained in the field for Sampling was performed weekly from September 2017 to June 2018.After collecting the adult flies, the content of each of the 16 subsamples were stored in sealed glass jars containing absolute alcohol (99%). Flies were quantified and identified in the lab by using an optical microscope.本研究采样工作于巴西米纳斯吉拉斯州内波穆塞诺市的圣安东尼奥笼养蛋鸡场（Aviário Santo Antônio）开展。研究人员随机布设四组盘式诱捕器（pan-traps）于该蛋鸡场的鸡笼旁：每组诱捕器包含四个分别涂有白、黄、红、蓝四色的塑料盆亚样本，因此野外共布设16个采样单元。每个塑料盆内均注入500ml添加了洗涤剂与食盐的水溶液，用于降低水的表面张力并保存采集到的蝇类。塑料盆置于野外期间，采样工作于2017年9月至2018年6月间每周开展一次。采集成虫蝇类后，将16个亚样本的全部内容物转移至装有无水乙醇（99%）的密封玻璃罐中保存。随后在实验室中借助光学显微镜对蝇类进行计数与种类鉴定。
