Fortnightly 25-hour catches, with human bait, were carried out in a modified environment of the "Jacaré-Pepira" River, Dourado County, S. Paulo, Brazil which is the original region of the "Araraquara" strain of Anopheles darlingi. The exophylic biting activity was mostly nocturnal with bimodal rhythm, showing two clear peaks corresponding, respectively, to dusk and dawn. Going into crepuscular ...

It has been used as carminative, anti-inflammatory, anti-abortion,vermifuge, bronchodilator and hypotensive. In the current study the locally cultured plant of Tagetes minuta L. was studied for phytochemical and larvicidal properties.The phytochemical analysis of aerial pa...

glutathione s-transferases (gsts) are a major family of detoxification enzymes which possess a wide range of substrate specificities. interest in insect gsts has primarily focused on their role in insecticide resistance. in this study, following world health organization (who) routine susceptibility test, dna was extracted from specimens of anopheles stephensi collected from the kazeroon distri...

b a ckground: a field study on diversity and distribution of anophelines currently present in a past endemic malaria area of spain was carried out in order to identify possible risk areas of local disease transmission. m e t hods: multiple larval sites were sampled from june to october of 2011 in the region of somontano de barbastro (northeastern spain). the sampling effort was fixed at 10 minu...

Two new species within the Anopheles gambiae complex are here described and named. Based on molecular and bionomical evidence, the An. gambiae molecular "M form" is named Anopheles coluzzii Coetzee & Wilkerson sp. n., while the "S form" retains the nominotypical name Anopheles gambiae Giles. Anopheles quadriannulatus is retained for the southern African populations of this species, while the Et...

Using carbon-dioxide-baited light traps and larval sampling, anopheline mosquitoes were collected from 620 sites in northern Australia. Twelve species were recorded. Anopheles annulipes s. l. (335 sites). An. bancroftii (181 sites), An. meraukensis (162 sites), An. farauti s. s. (133 sites), An. farauti 3 (93 sites), An. amictus (93 sites), An. hilli (88 sites), An. novaguinensis (70 sites), an...
