Why can't they just write this stuff in SIMPLE English?
Simply put, I THINK this study is saying essential oil from marigolds is effective in messing with female ticks ability to produce baby ticks. GOOD NEWS for us!
The oil messes with the female's eggs, which in turn would reduce the tick population over time.
The researchers feel it is better for the environment to use marigold oil rather than just the current insecticides on the market.
Parasitol Res. 2013 Jun;112(6):2261-8. doi: 10.1007/s00436-013-3386-3. Epub 2013 Mar 19.
Chemical characterization and acaricide potential of essential oil from aerial parts of Tagetes patula L. (Asteraceae) against engorged adult females of Rhipicephalus sanguineus (Latreille, 1806).

Rhipicephalus sanguineus, commonly known as the brown dog tick, is one of the most widely distributed species of tick. In dogs, it can cause anemia and provide the transmission of pathogenic microorganisms such as Babesia canis, Ehrlichia canis, Hepatozoon canis, Anaplasma platys, and Mycoplasma haemocanis.
To man, it can transmit the intracellular parasites Rickettsia rickettsii and Rickettsia conorii, the causative agents of the Rocky Mountain spotted fever in the Americas and Mediterranean and spotted fever in Europe and North Africa.
Its control is performed by applying synthetic formulations composed of pyrethroids; however, continued use of these products results in environmental damage and acquisition of resistance.
Alternatively, studies with botanical insecticides have been increasingly recurrent.
Therefore, this study aimed to test the efficacy of essential oil of Tagetes patula, a ruderal species widely described in the literature for its insecticidal properties, in engorged females of R. sanguineus by the adults immersion test (AIT) and impregnated paper disk test (IPDT).
The essential oil used, through gas chromatography coupled to mass spectrometry, revealed the presence of 55 compounds, being the 4-vinyl guaiacol and gamma terpinene the majority ones.
The AIT compared to the IPDT was more efficient in inhibiting oviposition of tick; however, the eggs laid by the females submitted to saturated atmosphere with essential oil, from IPDT, not hatched, interrupted their development cycle.
Besides being a pioneer work, the results presented here contributes to new researches, aiming the incorporation of essential oil in an acaricide for use in the environment. PMID: 23508761 [PubMed - in process]

HA! You make me laugh! And yes, with all those fancy terms, they could have just said- hey! Stick some marigolds in the yard, the stinkier the better!
Oh, I posted that last night and suddenly LN went down! I have another post that was to complement it, so I will post it below if I can find where I hid it!

I FOUND IT!!!! Amazing! hehehehehehehe
Marigolds have been used to repel bugs for a good while, but they don't work for ALL bugs.
This article, easy to read, says the stinkiest marigolds work best in the yard or garden to repel bugs, but there are some precautions to take if considering planting them, especially in the garden.

I wonder if it exists as an oil that you could buy. If so maybe we could dilute it spray it on ourselves and pets. We would stink but it may be worth it.
