“…aegypti. The compound exhibited a very high killing activity against mosquito larvae of both species at low concentration 9 . However, no studies have explored the mosquito larvicidal properties of the essential oil of the leaves of V. trifolia, except a study which reported the oviposition deterrent activity of the oil against adult mosquitoes 10 .…”

“…The leaves are opposite exstipulate, long petioled and 3-5 foliate which are all connected at one point and are elliptical and between 3 and 12 cm long. Flowers are light blue in terminal panicled cymes consist of a tube with five lobes; the central lobes is bigger than the others [6]. Plant leaves (3 kg) were collected from Mandi (H.P.)…”

S u m m a r y β-sitosterol and two triterpenoids: ursolic acid acetate and platanic acid have been isolated from ethanolic extract of Vitex trifola leaves. β-sitosterol was previously isolated from the leaves, stem and seeds of Vitex trifolia. Ursolic acid acetate has been isolated for the first time in this plant species. Platanic acid has been reported for the first time in Vitex trifolia and even in the family of this plant: Verbenaceae. These compounds were characterized using spectroscopic methods including 1D-1 HNMR, 13 CNMR, ESIMS and 2D-NMR (HSQC, HMBC, COSY) experiments and confirmed by comparison of their NMR data with those from the literature. A preliminary molluscicidal test for ethanol, chloroform and n-hexane extracts of leaves of Vitex trifolia against Biomphalaria alexandrina adult snails showed that ethanol extract of leaves with LC 50 value 26.42 mg/l (27.92 mg/l -24.99 mg/l) was more effective than n-hexane extract with LC 50 value 35.48 mg/l (43.81 mg/l -28.72mg/l) and chloroform extract with LC 50 value 46.77 mg/l (53.59 mg/l -43.81 mg/l) after 24 h exposure.

“…Globally, the number of dengue cases has increased drastically in the last decades, causing alarm about the risk of infection. 1,2 Climate change and resistance to synthetic pesticides are indicated as the main causes of the high dengue burden in developed and third world countries. There are currently no efficient antiviral drugs or vaccines to combat these diseases, so the main strategy for control focuses on preventing the vector proliferation.…”

Aedes aegypti is the main vector of three neglected tropical diseases: dengue, zika and chikungunya. Dengue is under surveillance by health organizations worldwide due to the risk of epidemics. Since there is no specific treatment for dengue, most studies have focused on preventing the reproduction and/or development of the mosquitoes. We studied the larvicidal activity of five phosphates and phosphorothioates derived from cardol, one of the four main components of cashew nut shell liquid (Anacardium occidentale L.), at different concentrations. The organophosphorothioate derivatives were tested for their in vitro inhibitory potential against acetylcholinesterase (AChE). One compound, Cdl.i-dPS (median lethal concentration (LC 50) = 0.8 ppm), was four times more efficient compared to an important commercial larvicide, Temephos (LC 50 = 3.2 ppm), and showed greater AChE inhibition than its monosubstituted analogue and Temephos.
