Aedes aegypti is responsible for the transmission of dengue, a disease that infects millions of people each year. Although essential oils are well recognized as sources of compounds with repellent and larvicidal activities against the dengue mosquito, much less is known about their oviposition deterrent effects. Commiphora leptophloeos, a tree native to South America, has important pharmacologi...

Sixty plant species were collected in the Ivory Coast on the basis of an ethnobotanical literature using the following three criteria: activity against worms, diarrhoea and/or abdominal pain. Eighty six plant extracts were prepared using 90% ethanol and tested for potential anthelminthic activities with a larvicidal test of Haemonchus contortus. 25.6% of the extracts showed a high activity, 12....

The larvicidal activity of hexane, chloroform and ethyl acetate leaf extracts of Strychnos nuxvomica against the third instar larvae of Culex quinquefasciatus was studied. The ethyl acetate leaf extract was found to be the effective larvicide with LC value of 222.28 and 146.99 ppm after 24 and 48 hours. The results indicate 50 promising larvicidal activity against Culex quinquefasciatus. Furthe...

Umbellularia californica (California bay laurel) and Laurus nobilis (Mediterranean bay laurel) leaves may be mistaken or used as a substitute on the market due to their morphological similarity. In this study, a comparison of anatomical and chemical features and biological activity of both plants is presented. L. nobilis essential oil biting deterrent and larvicidal activity were negligible. On...

In the current study, the mosquito larvicidal activity of leaf essential oils and their constituents from two eucalyptus species (Eucalyptus camaldulensis and Eucalyptus urophylla) against two mosquito species, Aedes aegypti and Aedes albopictus, was investigated. In addition, the chemical compositions of the leaf essential oils were analyzed using gas chromatography-mass spectrometry. Results ...

C. odorata L. is considered to be a plant weed that scattered in various climates. As weed, this contains variety of beneficial secondary metabolites. Several studies have shown the benefits leaf extract. This study reviews metabolite content and pharmacological activities A literature search was carried out obtain related use Secondary metabolites identified are alkaloids, flavonoids, tannins,...

BACKGROUND Application of plant derivatives have been suggested as alternative sources for mosquito control. METHODS The root essential oil and methanol extract of Cionura erecta (L.) Griseb was tested under laboratory conditions for larvicidal and skin repelleny activities against Anopheles stephensi. The chemical compositions of essential oils were analyzed using gas chromatography- mass sp...

Acute toxicities of 34 naturally occurring monoterpenoids were evaluated against 3 important arthropod pest species; the larva of the western corn rootworm, Diabrotica virgifera virgifera LeConte; the adult of the twospotted spider mite. Tetranychus urticae Koch; and the adult house fly. Musca domestica L. Potential larvicidal or acaricidal activities of each monoterpenoid were determined by to...

Over the world, more than 50% of persons with filariasis receive their infections from the bites of mosquitoes, particularly C. quinquefasciatus. Some photochemical comprise toxic compounds that can be exploited to control mosquito larvae. Gaultheria oil or wintergreen oil which contains methyl salicylate as a major component and has been used in the present study to investigate the larvicidal,...
