Recognizing the concerns, farmers are preferring use of natural alternatives to ward of insects and abate growth of bacteria and fungi, wherein citrus essential oils have gained increased visibility in light of their repellent, ovicidal, larvicidal, toxic, and antifeedant properties. 26/09/2013 · This study investigated the biological activities of five benthic marine algae collected from Northeastern Region of Brazil. The tested activities included larvicidal activity against Aedes aegypti, molluscicidal activity against Biomphalaria glabrata, and toxicity against Artemia salina. Extracts of Ulva lactuca (Chlorophyta

LARVICIDAL ACTIVITY OF INDIAN MEDICINAL PLANTS ON THE DENGUE FEVER MOSQUITO, AEDES AEGYPTI LINNAEUS J. Deepa1, J. Gokulakrishnan1*, M. Baranitharan2, and S. Dhanasekaran2 1Department of Zoology, Poompuhar College (Autonomous), Melaiyur-609 107, Tamilnadu, India. 19/04/2015 · Aedes aegypti and Aedes albopictus and Culex pipiens pallens mosquitoes transmit dengue fever and West Nile virus diseases, respectively. This study was conducted to determine the toxicity and mechanism of action of four flavonoids and two fatty acids from Millettia pinnata (Fabaceae) seed as well as six pure fatty acids and four fatty acid
The larvicidal activity of n-octyl 4-mercapto-2-butenoate against A. albopictus appears interesting and may be developed after toxicological evaluation on vertebrates and humans, and environmental toxicity tests in compliance with {WHO} and {ECDC} rules. During laboratory tests with the aqueous extract of Piper nigrum the FNS (2001) related a larval mortality of 80% after 64 h. Pohlit et al. (2004) performed a screening for larvicidal effects of several Amazon plants against A. aegypti, including some Piperaceae.
The insecticidal activity of materials derived from the fruits of Piper nigrum against third instar larvae of Culex pipiens pallens, Aedes aegypti, and A. togoi was examined and compared with that of commercially available piperine, a known insecticidal compound from Piper species. The biologically active constituents of P. nigrum fruits were LARVICIDAL ACTIVITY OF SOME SAPONIN CONTAINING PLANTS AGAINST THE DENGUE VECTOR AEDES AEGYPTI. Chetan S. Jawale P.G. Department of Zoology, H.P.T. Arts and R.Y. K Science College, Nashik 422005 India. ABSTRACT The crude extracts of fruits of Sapindus mukorossi, leaves of Cestrum nocturnm, Cestrum diurnum, and Asclepias
Aedes aegypti control with chemical insecticide is widely used, and affects on a widespread insecticide resistance. Mosquito biological control was needed to replace the use of chemical insecticide. This study aimed to evaluate larvicidal effect of mixture of Beauveria bassiana crude metabolite and chitinase enzyme against Aedes aegypti larvae. Larvicidal activity of temephos released from new chitosan/alginate/gelatin capsules against Culex pipiens Mohamed E. I. Badawy, Nehad E. M. Taktak, Osama M. Awad, Souraya A. Elfiki, Nadia E. Abou El-Ela Abstract A new controlled release capsules based on chitosan, alginate, and gelatin crosslinked with
neither the European Parliament nor the Council has opposed them, 4.10.2011 Official Journal of the European Union L 258/13EN. HAS ADOPTED THIS REGULATION: Article 1 Annexes II and III to Regulation (EC) No 396/2005 are amended in accordance with the Annex to this Regulation. During laboratory tests with the aqueous extract of Piper nigrum the FNS (2001) related a larval mortality of 80% after 64 h. Pohlit et al. (2004) performed a screening for larvicidal effects of several Amazon plants against A. aegypti, including some Piperaceae.
27/03/2012 · A preliminary study on larvicidal activity against laboratory-colonized Anopheles cracens mosquitos revealed that five of ten plant oils at concentration of 100 ppm showed 95–100% larval mortality. The essential oils of five plants, including Piper sarmentosum, Foeniculum vulgare, Curcuma longa, Myristica fragrans, and Zanthoxylum Larvicidal activity of aqueous and ethanol extract of C. didymobotrya was evaluated by using WHO method. Twenty five 2nd, 3rd, 4th and pupal stage was released in to 250 mL of glass beaker individually.
