Hadjelia truncata is a nematode that causes lesions in the gizzard lining of pigeons, which may even lead to death. The aim of this study was to introduce Alphitobius diaperinus as a new intermediate host for Hadjelia truncata.
H. truncata infection was identified in a pigeon flock in Ahvaz City, Khuzestan Province, Iran by performing fecal examination and autopsy. Adult and larval stages of beetles were collected from the litter of pigeon houses, and identified morphologically. The beetle larvae were cultured in a medium, containing feces of the infected pigeons. Nematode larval stages from naturally and experimentally (culturally) infected adult beetles were fed to two groups of pigeons
The collected beetles were identified as Alphitobius diaperinus. Average length and width of the adult beetles were 6.31 mm and 2.88 mm respectively. Infection rates of naturally and experimentally infected beetles with larval stages of the nematode were 66.2% and 45.1% respectively. The adult nematodes collected from gizzards of experimentally infected pigeons were identified as H. truncata. Nematode infection rates in pigeons after feeding the infective larvae collected from naturally and experimentally infected beetles were 44.7% and 32.5% respectively.
A. diaperinus can serve as a natural intermediate host for H. truncata.
截形哈氏线虫是一种可导致鸽子肌胃内膜出现病变甚至可能致死的线虫。本研究的目的是引入赤拟谷盗作为截形哈氏线虫的新中间宿主。
通过粪便检查和尸检在伊朗胡齐斯坦省阿瓦士市的一个鸽群中鉴定出截形哈氏线虫感染情况。从鸽舍垫料中收集甲虫的成虫和幼虫阶段,并进行形态学鉴定。将甲虫幼虫在含有感染鸽子粪便的培养基中培养。将自然感染和实验性(通过培养)感染的成年甲虫体内的线虫幼虫阶段喂给两组鸽子。
所收集的甲虫被鉴定为赤拟谷盗。成年甲虫的平均长度和宽度分别为6.31毫米和2.88毫米。线虫幼虫阶段自然感染和实验感染甲虫的感染率分别为66.2%和45.1%。从实验感染鸽子肌胃中收集的成年线虫被鉴定为截形哈氏线虫。喂食从自然感染和实验感染甲虫收集的感染性幼虫后,鸽子的线虫感染率分别为44.7%和32.5%。
赤拟谷盗可作为截形哈氏线虫的天然中间宿主。
