The sand fly (blood sucker), the Diptera Psychodidae is strongly attracted by the cannabis plant Sativa, but why?
Blood sucking flies (sand flies) are known to carry infectious diseases - but a study shows that they are strongly attracted to the cannabis plant Sativa. According to an article published in the journal Proceedings of the National Academy of Sciencesthe results may have implications for the control of sand fly populations (Diptera Psychodidae) worldwide. This is important because, just like closely related mosquitoes, sand flies can spread dangerous diseases ...
Cannabis Sativa attracts a large population of blood-sucking flies
TheIndependent reports that an international team of scientists found that, in proportion to its abundance, Cannabis Sativa was consumed by sand flies much more frequently than expected. Which suggests that it was very attractive to insects.
Flies are known to carry infectious diseases, such as leishmaniasis, which causes ulcers and many other viruses. malaria. According to a study published in the journal eLife, the animal transmits to humans, about 60% of emerging diseases. Thus, researchers must find new ways to detect these infectious pathogens in animals, especially flies. And, before an epidemic breaks out ...
Cannabis sap in the sand fly
For scientists who study flies like the blood-sucking fly, tsetse flies around the world, from Brazil to the Middle East, have noticed that the contents of the stomach of flies contain much more often than cannabis sap.
Sand flies suck blood at certain stages of development. Indeed, they also feed on the sweet sap of plants. However, in areas where flies are common, cannabis sativa rarely grows naturally . It is only a small fraction of the available food sources. In addition, a food so common in the stomach of flies must mean one thing. They are strongly attracted by this substance.
For the study - led by Ibrahim Abbasia from the Israel-Canada Institute of Medical Research and the Hebrew University of Jerusalem - researchers used light traps to catch sand flies in six unique areas spread across Brazil, Ethiopia, Kazakhstan and Israel. They then used next generation gene sequencing techniques to determine the types of flours that flies ate.
"We thought that sand flies that had been eating plants had genetic material [DNA] from the plants they had consumed. "Said Mr Warburg.
The study concludes on a surprising note, huge amounts of cannabis sap inhabited the stomach of these flies ... But the strangest, there is no receptors for cannabinoids in the body of flies. Thus, the exact nature of the attraction is still understood and requires further research ...
Cannabis Sativa, future fly trap?
Flies are usually trapped using sweet baits to help control their populations in problem areas. Adding cannabis plant material or even bait extracts can help trap them. And these Sativa cannabis traps, could catch more flies and further reduce the transmission of diseases.
