Abstract

The species Rhipicephalus sanguineus lato sensu (Ixodidae) is popularly known as brown dog tick" and causes economic and health losses for its parasite action and for being a vector of pathogens. Due to its importance in the control of tick metabolism, the central nervous system, CNS (synganglion) is one of the target organs of the action of acaricides. The intense and indiscriminate use of the synthetic acaricides has been causing environmental contamination and the selection of resistant populations, which stimulates the search for new alternatives and methods that are more efficient in their control. The insecticidal, fungicidal and antimicrobial action of the oils of two native species of Brazil, Egletes viscosa (Asteraceae) (macela) and Lippia schaueriana (Verbenaceae) (lipia da serra), has already been reported in the literature. This study has the objective of evaluate and compare how the singanglion of R. sanguineus ticks and the thyroid of Mus musculus mice (host model, non target organism) respond morphophysiologically to the action of the essential oils extracted from these plants. The present study will certainly contribute to the development of strategies to control these ectoparasites that improve both the quality of animal lives (considered non-target organisms) and minimize the environmental damage that has been caused by the indiscriminate use of acaricides in general.
