Anopheles stephensi is an important urban malaria vector, which is widely distributed throughout the Indian subcontinent. The said vector species has developed resistance to various insecticides and therefore, it is desirable to develop alternative strategies including genetic methods for its control. One of the requirements for such strategy is to establish morphological mutants and to establi...

in this study, the total 80% of meoh extract and also petroleum ether, chcl3, etoac, n-buoh, and the remaining meoh fractions obtained by solvent-solvent fractionation of the whole flowering samples of centaurea bruguierana (dc.) hand.-mzt. ssp. belangerana (dc.) bornm. (asteraceae), namely “baad-avard”, collected from borazjan in bushehr province (bushehr, iran) were investigated for larvicida...

The midgut microbiota associated with Anopheles stephensi and Anopheles maculipennis (Diptera: Culicidae) was investigated for development of a paratransgenesis-based approach to control malaria transmission in Eastern Mediterranean Region (EMR). Here, we present the results of a polymerase chain reaction (PCR) and biochemical-based approaches to identify the female adult and larvae mosquitoe m...

an interventional field trial study was carried out in the dehdahst area, kohgiloyeh & buyer ahmad province, iran, during 1997-1998. efficacy of deltamethrin-impregnated bednet at target dosage of 25 a.i. mg/m2 and the incidence of malaria were compared in treated and untreated villages. in this area anopheles superpictus is the dominant species and the activity of the species occurs in one pea...

Hexane extract of tuber of plant Cyperus rotundus (Cyperaceae) was screened under laboratory conditions for repellent activity against mosquito vector Anopheles culicifacies Giles species A (Diptera: Culicidae), Anopheles stephensi Liston (Diptera: Culicidae), and Culex quinquefasciatus Say (Diptera: Culicidae). The Cyperus rotundus tuber extract was used to determine their effect on mosquito v...

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...

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 ...
