Thymol-Loaded Polymeric Nanocapsules’ Repellent Activity on Nymphs of Rhipicephalus sanguineus Sensu Lato

Coatings
Thymol-loaded polymeric nanocapsules were developed in this study to control volatilization and drug release for repellent application on Rhipicephalus sanguineus nymphs. Policaprolactone-loaded nanocapsules were prepared and characterized by diameter, PdI, zeta potential, pH, entrapment efficiency, and thymol content.

Larvae of Ixodiphagus wasps (Hymenoptera: Encyrtidae) in Rhipicephalus sanguineus sensu lato ticks (Acari: Ixodidae) from Brazil

Ticks and Tick-borne Diseases, 2017
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
