In an experiment to investigate the effect of the tick parasitoid, Ixodiphagus hookeri, on tick numbers on cattle, 150000 parasitoids were released over a period of 1 year in a field where ten cattle infested with multiple tick species were kept. Amblyomma variegatum was reduced from 44 to two ticks per animal while Rhipicephalus appendiculatus increased over the time of parasitoid release. During the time of release 51% of the nymphs of A. variegatum collected from the animals were parasitized. The recovery of the parasitoids after the releases were stopped was only 9%. The total numbers of A. variegatum remained low up to 1 year after the parasitoid release was stopped. This study gives an insight into how I. hookeri could be used strategically for the management of A. variegatum on small-scale farms.
在一项调查蜱类寄生蜂——钩形嗜蜱螨（Ixodiphagus hookeri）对牛身上蜱虫数量影响的实验中，在一片饲养着十头感染多种蜱虫的牛的田地中，在1年的时间里释放了150000只寄生蜂。变异革蜱（Amblyomma variegatum）的数量从每头牛44只减少到了2只，而在释放寄生蜂期间，微小牛蜱（Rhipicephalus appendiculatus）的数量增加了。在释放期间，从牛身上采集的变异革蜱若虫中有51%被寄生。停止释放后，寄生蜂的回收率仅为9%。在停止释放寄生蜂后的1年内，变异革蜱的总数一直保持在较低水平。这项研究为如何在小规模农场中战略性地利用钩形嗜蜱螨来管理变异革蜱提供了见解。
