The histerid beetle Carcinops pumilio (Erichson) occurs naturally in poultry house manure and is an important predator of house fly eggs and larvae. Because efforts to commercially produce C. pumilio have been unsuccessful, one fly control strategy under consideration is the direct transport of adult C. pumilio between poultry houses to facilitate their establishment. However, we demonstrate that C. pumilio is a competent reservoir of Salmonella enteritidis (Gaertner). Adult C. pumilio exposed to S. enteritidis-inoculated house fly eggs harbored the bacterium externally and internally for up to 4 and 13 d, respectively, and feces were culture-positive for S. enteritidis for at least 14 d. This suggests that C. pumilio can be a reservoir of S. enteritidis; therefore its movement between poultry facilities should be carefully considered.
拟步甲科甲虫Carcinops pumilio（埃里希森）自然存在于禽舍粪便中，是家蝇卵和幼虫的重要捕食者。由于商业化生产C. pumilio的努力尚未成功，目前正在考虑的一种苍蝇控制策略是在禽舍之间直接运输成年C. pumilio，以促进其定殖。然而，我们证明C. pumilio是肠炎沙门氏菌（盖特纳）的有效宿主。暴露于接种肠炎沙门氏菌的家蝇卵的成年C. pumilio，其体表和体内分别携带该细菌长达4天和13天，粪便中肠炎沙门氏菌培养阳性至少持续14天。这表明C. pumilio可能是肠炎沙门氏菌的宿主；因此，应谨慎考虑其在禽类设施之间的移动。
