Dermanyssus gallinae (Mesostigmata: Dermanyssidae), a mite of poultry, represents the most important ecotoparasite of egg-laying poultry in several countries. We estimated the prevalence of D. gallinae infestation in 38 industrial poultry farms (28 egg-laying and 10 reproductive hen farms) in the governorate of Nabeul (North-East Tunisia). Traps were placed in two locations of each farm during 24 h in August. The overall prevalence at the farms was estimated to be 34%. A total number of 329 D. gallinae were collected, giving an intensity of 0.0028 and an abundance of 0.0015. Infestation intensity and abundance were significantly higher in egg production farms than reproductive farms. There was no correlation between the intensity of infestation and temperature. An exponential correlation was observed between the birds' age and infestation intensity. We recommend a systematic survey of poultry farms during the whole breeding period. Prompt treatment is recommended to avoid the exponential increase of mite population.
鸡皮刺螨(中气门目:皮刺螨科)是一种家禽螨虫,在多个国家是产蛋家禽最重要的生态外寄生虫。我们估计了突尼斯东北部纳布勒省38个工业化家禽养殖场(28个产蛋场和10个种母鸡场)鸡皮刺螨的感染率。8月期间,在每个养殖场的两个地点放置诱捕器24小时。养殖场的总体感染率估计为34%。共收集到329只鸡皮刺螨,感染强度为0.0028,感染丰度为0.0015。产蛋场的感染强度和丰度显著高于种鸡场。感染强度与温度之间没有相关性。观察到鸡的年龄与感染强度之间呈指数相关。我们建议在整个养殖期对家禽养殖场进行系统调查。建议及时治疗以避免螨虫数量呈指数增长。
