susceptibility levels of a lab strain of an. stephensi to who standard papers of ddt 4%, dieldrin 0.4%, malathion 5%, permethrin 0.25%, lambdacyhalothrin 0.1%, cyfluthrin 0.1% and deltamethrin 0.025% were determined in our laboratory in 1999. results showed that at the diagnostic dose of insecticides this species exhibited resistance to ddt and dieldrin with mortality rate of 54±2.5% and 30±2.5...

In both malanal oes mosquitoes are breeding. The mo q port transmitting malaria are according to a, i< \ ? ....

background: application of plant extracts as mosquito control strategy was practiced from centuries. these are easily available, non-toxic, biodegradable and exhibit broad-spectrum target specific activities against larval stages of mosquitoes. method: different potential parts of locally grown plants, seeds of nutmeg ( myristica fragrans ), peel of musambi ( citrus sinensis ), leaves of babuna...

the first records of anopheles fluviatilis resistance to ddt was reported in 1963 from india and to dieldrin from eastern saudi arabia in 1959. in southern iran, antimalaria measures began in 1950 and up to 1957 the area was under ddt residual house spraying at the rate of 2g /m2 one round/year. during 1958-59 dieldrin was used at 0.5 g/m2, 1or 2 rounds/year was applied in the lowland areas. in...

b a ckground: the role of lectins is important in interaction between pathogens and mosquito vectors. this study was performed to identify agglutinin activities of protein molecules on the midgut of culex pipiens . m e t hods: c u lex pipiens was reared in insectray condition and the midguts of males and females (blood fed and un- fed) were dissected separately in tris-hcl buffer. the extracts ...

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...

background: there are unorganized, published documents about the ecology of mosquitoes (diptera: culicidae) in northeastern part of iran. the purpose of this study was to determine the distribution and characteristics of larval habitats of culicidae in kalaleh county. methods: larvae were collected using dipping method and adults by human landing catch technique during april–october, 2012. larv...

Dengue is a vector-borne disease caused by dengue virus. According to the recent report of CDC that one-third population of the world are at high risk with Dengue fever. The prevalence of the dengue hemorrhagic fever was found more in tropical and sub-tropical regions of the world. Aedes mosquitoes was reported as the main cause of transmission of dengue virus.
