Study Data from University of Burdwan Update Understanding of Allelopathy

June 17, 2014

By a News Reporter-Staff News Editor at Life Science Weekly -- Researchers detail new data in Life Science Research. According to news reporting originating from Bengal, India, by NewsRx correspondents, research stated, "Extraction, thin layer chromatography and gas chromatography-mass spectrometry of Momordica cochinchinensis Spreng (Cucurbitaceae) flowers revealed 13 free fatty acids, and a single flower indicated presence of 364.70 +/- 0.04 mu g free fatty acids. Myristic and tridecanoic acids were the predominant and least abundant free fatty acids, representing for 97.38 +/- 0.76 and 4.86 +/- 0.01 mu g in a single flower, respectively."

Our news editors obtained a quote from the research from the University of Burdwan, "The 'free fatty acids from flowers at 1, 2, 4, 6, 8, and 10 mu g concentrations and synthetic blends of fatty acids mimicking different concentrations of flower free fatty acids elicited attraction of female Aulacophora foveicollis Lucas (Coleoptera: Chrysomelidae) between 1-10 mu g concentrations in Y-shaped glass tube olfactometer bioassay under laboratory condition. The individual synthetic fatty acids mimicking the proportions of fatty acids detected in flowers at different concentrations were also evaluated. Individual synthetic myristic, paltnitoleic, alinolenic, and nonadecanoic acids at the minimal amounts of 2.67, 0.56, 0.11, and 0.99 pig, respectively, elicited attraction of the insect."

According to the news editors, the research concluded: "A synthetic blend of 1.60, 0.56, 0.17, and 0.59 mu g of myristic, palmitoleic, alpha-linolenic, and nonadecanoic acids, respectively, was most attractive to the insect, and hence, this combination might be used for insect pest management programme such as baited traps."
