Article Synopsis
- Rhipicephalus sanguineus ticks are major ectoparasites that harm dogs, leading to both direct and indirect damage.
- Current control methods rely largely on synthetic acaricides, but resistance to these treatments is increasing, prompting research into natural compounds.
- The study evaluates the effectiveness of combining fipronil with eugenol or carvacrol and finds that while FIP combined with EUG or CAR shows antagonistic effects, EUG and CAR together exhibit strong synergism, achieving high mortality rates across all tick life stages.
The objective of this work was to evaluate the susceptibility of larvae from different oviposition times to fipronil. The LPT was performed in sextuplicate, at concentrations of 18.75, 37.

The chemical composition of EO was determined by gas chromatography (GC). To evaluate the insecticidal activity, the egg, larva, pupa, and adult stages of were exposed to different concentrations of EO diluted in acetone and impregnated in filter paper in a concentration range of 25 to 200 μg.

Article Synopsis
- Fleas and ticks are major pests for pets, and their control often leads to issues like insect resistance and environmental harm from chemical antiparasitics.
- The study aimed to explore the effectiveness of Ocimum gratissimum essential oil and eugenol against fleas and ticks, focusing on their safety and development of a natural product-based spray.
- Results showed that eugenol had strong pest-killing properties and the developed eugenol-based spray was effective for at least 48 days, indicating a promising alternative to synthetic treatments.
Efficacy and residual effect of Illicium verum (star anise) and Pelargonium graveolens (rose geranium) essential oil on cat fleas Ctenocephalides felis felis.

The essential oils (EOs) of Illicium verum and Pelargonium graveolens were evaluated for lethality, inhibition of development and residual efficacy against the flea Ctenocephalides felis felis. Their chemical composition was characterized by means of gas chromatography with a flame ionization and mass spectrometry detection. Mortality at different immature stages and among adult fleas was measured through in vitro filter paper tests at different concentrations of EOs.

Currently, the control of this parasite is mainly through chemicals. However, the indiscriminate use of these substances generates resistance.
