A piperidine amide extracted from Piper longum L. fruit shows activity against Aedes aegypti mosquito larvae

Yang, Y. C., Lee, S. G., Lee, H. K., Kim, M. K., Lee, S. H., Lee, H. S.
J Agric Food Chem 50(13), 3765-7. (Jun 19 2002)

Mosquito larvicidal activity of Piper longum fruit-derived materials against the fourth-instar larvae of Aedes aegypti was examined. A crude methanol extract of P. longum fruits was found to be active against the larvae, and the hexane fraction of the methanol extract showed a strong larvicidal activity of 100% mortality. The biologically active co...

Challenges encountered using standard vector control measures for dengue in Boa Vista, Brazil

Maciel-de-Freitas, R., Valle, D.
B World Health Organ 92(9), 685-689. (Sep 2014)

Problem in 2010, dengue virus (DENV) serotype-4 was detected during a dengue outbreak in the Amazonian city of Boa:Vista. At that time Brazil was already endemic for DENV-1, DENV-2 and DENV-3. This was the first time DENV-4 was observed in the country after it was initially detected and eliminated in 1981. Approach To hinder the spread of DENV-4 th...

Characterization of Spatial Repellent, Contact Irritant, and Toxicant Chemical Actions of Standard Vector Control Compounds

Achee, N. L., Sardelis, M. R., Dusfour, I., Chauhan, K. R., Grieco, J. P.
J Am Mosquito Contr 25(2), 156-167. (Jun 2009)

A previously described modular high-throughput screening system was used to characterize the spatial repellent, contact irritant, and toxicant chemical actions of 14 compounds historically used or under investigation for vector control. The response of F(1)-F(4) Aedes aegypti (Thailand strain) to various concentrations of 4 organochlorines (chlorda...

Defence mechanisms against insecticides temephos and diflubenzuron in the mosquito Aedes caspius: the P-glycoprotein efflux pumps

Porretta, D., Gargani, M., Bellini, R., Medici, A., Punelli, F., Urbanelli, S.
Med Vet Entomol 22(1), 48-54. (Mar 2008)

P-glycoproteins (P-gps) are efflux transporters found in cells of a broad range of both procaryotic and eukaryotic taxa, whose action is to relieve the cells of multiple, structurally dissimilar, toxic compounds. The possible role of P-gps in defence against the insecticides temephos and diflubenzuron was investigated in the mosquito Aedes caspius ...

Detection of insecticide resistance in Aedes aegypti (Diptera: Culicidae) from Cuba and Venezuela

Rodriguez, M. M., Bisset, J., de Fernandez, D. M., Lauzan, L., Soca, A.
J Med Entomol 38(5), 623-8. (Sep 2001)

Four strains of Aedes aegypti (L.), one from Cuba and three from Venezuela, were bioassayed for susceptibility to eight insecticides, including the organophosphates, temephos, malathion, fenthion, pirimiphos methyl, and chlorpyrifos, and the pyrethroids, deltamethrin, lambda cyhalothrin and cypermethrin, S, S, S,-tributyl phosphorotrithioate and pi...

Determination of Toxicity and Igr Effect of Diflubenzuron and Rb-B Formulation on the Larvae of Aedes-Aegypti

Naqvi, S. N. H., Azmi, M. A., Jahan, M., Naz, U., Akhtar, K.
Natl Acad Sci Lett 17(9-10), 193-194. (Sep-Oct 1994)

Insect growth regulators have obtained an important pest management. The present report deals with the determination of toxic and IGR effects of diflubenzuron and RB-b (an extract of air-dried fruit of neem) against 4th instar larvae of Aedes aegypti. The neem extract RB-b was used with a synergist (RB-b + PBO + Tx - 100).

Ecotoxicity and Environmental Risk Assessment of Larvicides Used in the Control of Aedes Aegypti to Daphnia Magna ( Crustacea, Cladocera)

Abe, F. R., Coleone, A. C., Machado, A. A., Machado-Neto, J. G.
J Toxicol Env Heal A 77(1-3), 37-45. (Feb 1 2014)

Dengue transmitted by mosquitoes of the genus Aedes, species aegypti, is a major public health concern in Brazil. The chemical control of the mosquito larvae has been performed with the larvicide temephos since 1967. However, vector resistance was reported to temephos in several Brazilian states, and the Ministry of Health ordered the replacement o...

Effect of Aedes aegypti exposure to spatial repellent chemicals on BG-Sentinel (TM) trap catches

Salazar, F. V., Achee, N. L., Grieco, J. P., Prabaripai, A., Ojo, T. A., Eisen, L., Dureza, C., Polsomboon, S., Chareonviriyaphap, T.
Parasite Vector 6. (May 20 2013)

Background: An integrated approach to reduce densities of adult Aedes aegypti inside homes is currently being evaluated under experimentally controlled field conditions. The strategy combines a spatial repellent (SR) treatment (applied indoors) with the Biogents Sentinel (TM) (BGS) mosquito trap positioned in the outdoor environment. In essence, wh...

Effect of Novaluron (Rimon 10 EC) on the mosquitoes Anopheles albimanus, Anopheles pseudopunctipennis, Aedes aegypti, Aedes albopictus and Culex quinquefasciatus from Chiapas, Mexico

Arredondo-Jimenez, J. I., Valdez-Delgado, K. M.
Med Vet Entomol 20(4), 377-87. (Dec 2006)

Dengue fever is a serious problem in Mexico and vector control has not been effective enough at preventing outbreaks. Malaria is largely under control, but it is important that new control measures continue to be developed. Novaluron, a novel host-specific insect growth regulator and chitin synthesis inhibitor, has proved to be effective against ag...
