Background Malarious areas in Iran are close to Afghanistan and Pakistan that urge the researchers to extend their knowledge on malaria epidemiology to the neighboring countries as well. Vectorial capacity differs at species or even at population level, the first essential step is accurate identification of vectors. This study aimed to identify Anopheles species composition in selected malariou...

Petroleum ether extract of Blumea lacera was screened under laboratory conditions for repellent activity against mosquito vector Anopheles stephensi Liston and Culex quinquefasciatus Say (Diptera: Culicidae). The repellent activity of Blumea lacera extract was tested against mosquitoes in comparison with the DEET, which was used as a positive control. Results obtained from the laboratory experi...

Malaria in Goa, India, has been endemic ever since an outbreak occurred in 1986. Anopheles stephensi Liston has always been suspected as a malaria vector in this area. Due to lack of knowledge on its resting behavior, sufficient adult females could not be collected and incriminated as vectors in the past. In this study mosquito collections were conducted in three endemic urban and suburban area...

Anopheles stephensi Liston (Diptera: Culicidae) is the urban vector of malaria in the Indian subcontinent and several countries of the Middle East. The genetics of propoxur resistance (pr) in An. stephensi larvae was studied to determine its mode of inheritance. A diagnostic dose of 0.01 mg/L as recommended by WHO was used to establish homozygous resistant and susceptible strains. Reciprocal cr...

OBJECTIVE To determine the larvicidal and repellent activities of Coccinia (C) indica Wight and Arnold (Family:Cucurbitaceae) extract against Culex (Cx.) quinquefasciatus, Aedes (Ae.) aegypti and Anopheles (An.) stephensi. MATERIALS AND METHODS The ovicidal activity was determined against three mosquito species to various concentrations ranging from 50-300 ppm under the laboratory conditions....

Laboratory bioassay of the essential oil extracted from an indigenous plant, Ipomoea cairica, commonly known as 'Railway creeper', was carried out against the larvae of four vector species of mosquitoes in order to evaluate its mosquito larvicidal effect. Bioassay test revealed that the essential oil of the plant possess remarkable larvicidal properties as it could induce 100% mortality in the ...

BACKGROUND & OBJECTIVES In view of the recently increased interest in developing plant origin insecticides as an alternative to chemical insecticide, this study was undertaken to assess the larvicidal and ovicidal potential of the crude hexane, benzene, chloroform, ethyl acetate and methanol solvent extracts from the medicinal plant Pithecellobium dulce against the mosquito vectors, Anopheles s...

Animal models are often used to study hematophagous insect feeding behavior and evaluate products such as topical repellents. However, when these models are used the study animals often experience significant drops in core body temperature because of the effects of anesthesia. This study used a guinea pig model to investigate whether maintaining a normothermic core body temperature during anest...

Rabbit antibodies to hemolymph antigens (102.5, 101, 100, 96, 88, 80, 64, 55, 43, 29, and 23 kDa) of Anopheles stephensi reduced fecundity as well as viability in An. stephensi. However, ingestion of these antibodies was not associated with a marked effect on the engorgement of mosquitoes but egg laying was significantly delayed. Antisera raised against hemolymph proteins were also used to iden...

The objective of the present study is to determine the bioefficacy of different crude extracts of Ajuga remota against anopheline and culicine larvae. Larval susceptibility of crude carbon-tetrachloride, methanol and petroleum-ether extracts of Ajuga remota leaves was observed against the malaria vector, Anopheles stephensi and the filariasis vector, Culex quinquefasciatus. Among the extracts t...
