Ornithonyssus sylviarum is a blood-feeding ectoparasite of birds and the most serious pest in poultry farms in North America. Although the mites are typically adapted to temperate climates, information on this mite in Europe is sparse, and Dermanyssus gallinae is considered to be the only mite impacting the poultry industry. The present study reports the occurrence of O. sylviarum in pet birds in Portugal. Mites were collected directly from birds and with traps placed in cages and nests at 20 different sampling places belonging to 6 municipalities in the district of Setúbal. In a total of 217 birds, O. sylviarum was identified in 47 out of 147 (32.0%) canaries (Serinus canaria), 14 out of 21 (14.3%) estrildid finches, 1 out of 24 (4.2%) budgerigars (Melopsittacus undulatus) and 1 out of 15 (6.7%) lovebirds (Agapornis spp.). Mites of the genus Dermanyssus were identified in 8 canaries (5.4%), 8 estrildid finches (38.1%) and 1 lovebird (6.7%). No mites were found in 6 cockatiels (Nymphicus hollandicus), 2 African grey parrots (Psittacus erithacus), 1 Bourke's parrot (Neophema bourkii) and 1 rose-ringed parakeet (Psittacula krameri). Considering the zoonotic potential and the risk of dissemination to poultry, the present findings underline the need for further monitoring of O. sylviarum in the wild and domestic avifauna in Portugal.
鸡皮刺螨是鸟类的吸血外寄生虫，也是北美家禽养殖场最严重的害虫。尽管这种螨虫通常适应温带气候，但欧洲关于这种螨虫的信息很少，而鸡皮刺螨被认为是唯一影响家禽业的螨虫。本研究报告了葡萄牙宠物鸟中鸡皮刺螨的出现情况。螨虫直接从鸟类身上采集，并在塞图巴尔区6个市的20个不同采样点的笼子和鸟巢中放置诱捕器进行采集。在总共217只鸟中，在147只（32.0%）金丝雀（Serinus canaria）中的47只、21只（14.3%）梅花雀中的14只、24只（4.2%）虎皮鹦鹉（Melopsittacus undulatus）中的1只以及15只（6.7%）情侣鹦鹉（Agapornis spp.）中鉴定出鸡皮刺螨。在8只金丝雀（5.4%）、8只梅花雀（38.1%）和1只情侣鹦鹉（6.7%）中鉴定出皮刺螨属螨虫。在6只鸡尾鹦鹉（Nymphicus hollandicus）、2只非洲灰鹦鹉（Psittacus erithacus）、1只伯克氏鹦鹉（Neophema bourkii）和1只玫瑰环鹦鹉（Psittacula krameri）中未发现螨虫。考虑到其人畜共患病潜力以及传播到家禽的风险，本研究结果强调有必要对葡萄牙野生和家养鸟类中的鸡皮刺螨进行进一步监测。
