To facilitate physical genome mapping, we have developed a new cytogenetic photomap for Anopheles stephensi (Liston) (Diptera: Culicidae), an important malaria vector in Asia. The high-resolution images of the ovarian polytene chromosomes have been straightened and divided by numbered divisions and lettered subdivisions. The exact chromosomal locations of eight DNA probes have been determined b...

BACKGROUND Recently, essential oils and extracts derived from plants have received much interest as potential bio-active agents against mosquito vectors. METHODS The essential oils extract from fresh peel of ripe fruit of Citrus aurantium and Citrus paradisi were tested against mosquito vector Anopheles stephensi (Diptera: Culicidae) under laboratory condition. Then chemical composition of th...

Larvicidal efficacy of the aqueous and methanol extracts from green unripe and yellow ripe fruits, seeds, leaves and roots of the plant Solanum xanthocarpum was evaluated against Anopheles culicifacies, Anopheles stephensi, Aedes aegypti and Culex quinquefasciatus, the important mosquito vectors prevalent in the arid region. Studies were carried out on late 3rd orearly 4th instarlarvae of these...

The 3-hydroxykynurenine transaminase (3-HKT) gene plays a vital role in the development of malaria parasites by participating in the synthesis of xanthurenic acid, which is involved in the exflagellation of microgametocytes in the midgut of malaria vector species. The 3-HKT enzyme is involved in the tryptophan metabolism of Anophelines. The gene had been studied in the important global malaria ...

background and objectives: malaria is a remarkable cause of death in the world. several ways are used by researchers to control or to decrease the detrimental effects of the disease, in which natural insecticides with less malaria vectors resistance and lower environmental damages are considered in last decades.the objective of this study was to assess the larvicidal activity of the whole flowe...

Abstract Anopheles stephensi mosquitoes share urban breeding sites with Aedes aegypti and Culex quinquefasciatus in the Republic of Djibouti. We present evidence that A. might be responsible for an increase malaria incidence this country. also document resistance Plasmodium falciparum to dihydroartemisinin/piperaquine.

Vector borne diseases are affecting millions of people annually. Entomopathogenic fungi toxicity on malaria vectors increase mortality rates, and are less effective on nontarget organisms, thus representing a control measure that could be used in integrated programmes. Before metabolites of entomopathogenic fungi can be integrated into control programmes, an effective delivery system must be de...

The cibarial armature of Anopheles (Cellia) stephensi Liston and Anopheles (Cellia) culicifacies Giles are described in detail for first time with the aid of SEM. A description of cibarial armature includes lateral flanges and cibarial teeth. Besides this, the number, distribution and type of sense organs also described.

Malaria parasite (Plasmodium spp.) infection in the mosquito Anopheles stephensi induces significant expression of A. stephensi nitric oxide synthase (AsNOS) in the midgut epithelium as early as 6 h postinfection and intermittently thereafter. This induction results in the synthesis of inflammatory levels of nitric oxide (NO) in the blood-filled midgut that adversely impact parasite development...
