Natural enemies of ticks include the parasitoid wasp Ixodiphagus hookeri (Hymenoptera: Encyrtidae). The aim of this preliminary study was to investigate the occurrence of I. hookeri DNA in a community of ticks (Ixodes ricinus, Dermacentor marginatus, Hyalomma marginatum, Haemaphysalis inermis and Rhipicephalus turanicus). From May 2010 to March 2012, ticks were collected monthly by dragging and flagging, identified, and 481 adults and 305 nymphs screened molecularly for infection with I. hookeri. Of the samples tested (n=786), 3.1% (n=25) were positive for I. hookeri DNA, 7.2% (n=22) in nymphs and 0.6% (n=3) in adults. I. hookeri DNA was only detected in I. ricinus. This study shows that I. hookeri infests I. ricinus in southern Italy, with nymphs being the main developmental stage affected by this wasp.
蜱的天敌包括寄生蜂钩形嗜蜱螨（膜翅目：跳小蜂科）。这项初步研究的目的是调查在蜱类群落（蓖麻硬蜱、边缘革蜱、边缘璃眼蜱、无盾血蜱和图兰扇头蜱）中钩形嗜蜱螨DNA的存在情况。2010年5月至2012年3月，每月通过拖拽和挥旗法收集蜱，进行鉴定，并对481只成虫和305只若虫进行钩形嗜蜱螨感染的分子筛查。在测试的样本（n = 786）中，3.1%（n = 25）的样本钩形嗜蜱螨DNA呈阳性，若虫中为7.2%（n = 22），成虫中为0.6%（n = 3）。仅在蓖麻硬蜱中检测到钩形嗜蜱螨DNA。这项研究表明，在意大利南部，钩形嗜蜱螨寄生于蓖麻硬蜱，若虫是受这种黄蜂影响的主要发育阶段。
