The siphon indices, branching of setae 5-C and 6-C, lengths of 5-C compared to the lengths of 6-C, length of the most proximal seta 1-S compared to the siphon length, and the occurrence of a paler abdominal segment IV were compared among Culex apicalis, Cx. boharti and Cx. territans larvae. These characters in Cx. territans were found to be much more variable than previously recognized, and oft...

3. Since Lp and Lr are subspaces of CX , their intersection is a vector space. It is clear that ‖ · ‖ is a norm (this follows directly from the fact that ‖ · ‖p and ‖ · ‖r are norms). Let 〈fn〉n=1 be a Cauchy sequence in Lp ∩ Lr. Since ‖fm − fn‖p ≤ ‖fm − fn‖ and ‖fm − fn‖r ≤ ‖fm − fn‖ for all m,n ∈ N, it is clear that 〈fn〉n=1 is a Cauchy sequence in both Lp and Lr. Let gp ∈ Lp and gr ∈ Lr be the...

We report construction of a comparative linkage map for the mosquito (Culex pipiens) based on restriction fragment length polymorphisms (RFLPs) using cDNA clones from Aedes aegypti as probes to Southern blots of Cx. pipiens genomic DNA. Seventy-one cDNA clones were screened for hybridization and genetic diversity among three Cx. pipiens strains. Fifty-two of 71 cDNA clones, isolated from and pr...

background : mosquitoes are considered as the vectors of dirofilariasis and some vector borne disease in iran. the objective of this study was to determine the susceptibility level of the vectors to various insecticides recommended by who for any control measures in an endemic area in northwestern iran. methods : mosquito larval and adult collections were carried out using different methods pro...

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...

Abstract Background Chest pain in aortic stenosis (AS) has been attributed to the loss of coronary flow reserve however; this not directly quantified date. Purpose To determine whether there is a decrease as cause chest or dyspnea patients with severe AS Methods Patients and normal left ventricular ejection fraction (LVEF) underwent coronariography previous valve replacement. In those without o...

We isolated Sindbis virus (SINV) from the enzootic mosquito vectors Culex torrentium, Cx. pipiens, and Culiseta morsitans collected in an area of Sweden where SINV disease is endemic. The infection rate in Cx. torrentium mosquitoes was exceptionally high (36 infections/1,000 mosquitoes), defining Cx. torrentium as the main enzootic vector of SINV in Scandinavia.
