Abstract

The biological control of ticks represents an alternative method to the chemical control, given its ecological-friendly approach. Amongst the alternatives, the use of parasitoids of the genus Ixodiphagus (Hymenoptera: Encyrtidae) has been largely investigated. The aim of this study was to document and molecularly characterize Ixodiphagus wasps in ticks from a tropical region of Brazil. From October 2015 to March 2016, Rhipicephalus sanguineus sensu lato ticks (n=1814) were collected from naturally infested dogs and Ixodiphagus larvae were detected by microscopic examination. In addition, adult wasps were obtained in the laboratory. Larvae and adults were molecularly identified as Ixodiphagus hookeri. These findings suggest that this type of parasitism deserves to be studied in local tick populations, in order to elucidate the role of these wasps as a potential alternative to chemical tick control.

摘要

鉴于其生态友好的方法，蜱的生物防治是化学防治的一种替代方法。在各种替代方法中，对硬蜱啮小蜂属（膜翅目：跳小蜂科）寄生蜂的使用进行了大量研究。本研究的目的是记录和分子鉴定来自巴西热带地区蜱中的硬蜱啮小蜂属黄蜂。2015年10月至2016年3月，从自然感染的犬只身上采集了1814只血红扇头蜱（狭义），通过显微镜检查检测到硬蜱啮小蜂属幼虫。此外，在实验室中获得了成年黄蜂。幼虫和成虫经分子鉴定为胡氏硬蜱啮小蜂。这些发现表明，这种寄生现象值得在当地蜱种群中进行研究，以阐明这些黄蜂作为化学蜱控制潜在替代方法的作用。
