Andrographis paniculata leaf extracts: A natural mosquito control agent in combating Aedes Aegypti and Culex quinquefasciatus

Malathion resistance in Aedes aegypti and Culex quinquefasciatus after its use in Aedes aegypti control programs.

The continued widespread use of malathion in Aedes aegypti control programs in Latin America has generated insecticide resistance to this chemical in Culex quinquefasciatus but not in Ae. aegypti. To determine the extent of this resistance, the susceptibility of Cx. quinquefasciatus and Ae. aegypti from several countries to malathion was evaluated. Bioassay results indicated that all Ae. aegypt...

Efficacy and Sublethal Effects of Mosquito Mats on Aedes Aegypti and Culex Quinquefasciatus (diptera: Culicidae)

Mosquito mats with active ingredient d-allethrin (36 mg/mat) and prallethrin (15 mg/mat) were tested in the laboratory against Aedes aegypti (L.) and Culex quinquefasciatus (Say) using test method of the Standard and Industrial Research Institute of Malaysia. Results indicated that KT50 values for d-allethrin against Ae. aegypti and Cx. quinquefasciatus were 1.38 min and 8.36 min, respectively....

Mosquito larvicidal properties of Mirabilis jalapa (Nyctaginaceae) against Anopheles stephensi, Aedes aegypti & Culex quinquefasciatus (Diptera: Culicidae)

A laboratory study of cyromazine on Aedes aegypti and Culex quinquefasciatus and its activity on selected predators of mosquito larvae.

In a laboratory study, the insect growth regulator, cyromazine, exerted a high level of biological activity on Aedes aegypti and Culex quinquefasciatus treated in the 4th larval instar. At 1.5 and 1.0 ppm this IGR produced 97 and 99% inhibition of emergence in adult Ae. aegypti, respectively. In Cx. quinquefasciatus, there was 99% inhibition at 1 ppm and complete inhibition at 1.5 ppm. The over...

Experimental infection of Culex (Culex) quinquefasciatus and Aedes (Stegomyia) aegypti with Wuchereria bancrofti.

A study was conducted to determine the susceptibility of local strains of Culex quinquefasciatus and Aedes aegypti to infection with the strain of Wuchereria bancrofti that occurs in Maceió. State of Alagoas, Brazil. Cx. quinquefasciatus blood fed simultaneously on the same microfilariae carrier ingested more blood and 2-3x more microfilariae than Ae. aegypti. Survival rates of both species of ...
