background : one of the best ways to control the malaria disease and to be protected human against anopheles mos­quito biting is the use of repellents. throughout repellents, herbal ones may be an appropriate and safe source for protection. methods : chemical constituents of achillea vermiculata and satoreja hortensis were determined by using gas chromatography-mass spectrometry. efficacy and t...

Anopheles subgenus Nyssorhynchus is a monophyletic Neotropical group (Sallum et al. 2000, 2002) that currently contains 32 named species (Harbach 2004). The most important vectors of human malaria parasites in Central and South America are members of the subgenus and include An. darlingi Root, 1926, An. albimanus Wiedemann, 1820 and An. marajoara Galvão & Damasceno, 1942 (Conn et al. 2002). Ano...

Mosquito species were sampled to determine the mosquito composition and abundance in rice field and plantation communities in Ogun State Nigeria. Mosquitoes were caught once weekly from four selected houses in each of the two communities by means of CDC light traps. A total of 47,501 mosquitoes representing fifteen species were caught in the two communities of which the rice field community acc...

OBJECTIVE To investigate the larvicidal efficacy of different extracts of Ficus benghalensis L. against Culex quinquefasciatus Say, Aedes aegypti L. and Anopheles stephensi L. (Diptera: Culicidae). MATERIALS AND METHODS Larvicidal efficacy of the crude leaf extracts of Ficus benghalensis with three different solvents like methanol, benzene and acetone was tested against the early second, thir...

BACKGROUND Several important diseases are transmitted by mosquitoes. Despite of the potential of the occurrence of some mosquito-borne diseases such as West Nile, dirofilariasis and malaria in the region, there is no recent study of mosquitoes in West Azerbaijan Province. The aim of this investigation was to study the fauna, composition and distribution of mosquitoes and the characteristics of ...

Millions of people die each year as a result of pathogens transmitted by mosquitoes. However, the morphological identification of mosquito species can be difficult even for experts. The identification of morphologically indistinguishable species, such as members of the Anopheles maculipennis complex (Diptera: Culicidae), and possible hybrids, such as Culex pipiens pipiens/Culex pipiens molestus...

BACKGROUND Ecological studies on mosquitoes are very important in vector control programs. There are a few studies about the ecology of mosquitoes in northern Iran. This study was carried out to detect fauna and larval habitat characteristics of mosquitoes. METHODS This study aimed to determine fauna and the ecology of mosquitoes in Neka County, Mazandaran Province, northern Iran from April t...
