| tests for the existence of genetic variability in the tendency of anopheles culicifacies species b to rest in houses and to bite man. | experiments were carried out in sri lanka on the malaria vector anopheles culicifacies using the mark-release-recapture technique. collections were made in cattle-baited huts fitted with exit traps, and in nightbiting catches on human subjects. the same individual mosquitos were caught biting cattle and man on different occasions and the numbers caught demonstrated an overall preference for the cattle. the mean interval between successive blood meals in the field was estimated to be 2.3 days.fol ... | 1982 | 6982776 |
| susceptibility of species a, b, and c of anopheles culicifacies complex to plasmodium yoelii yoelii and plasmodium vinckei petteri infections. | the comparative susceptibilities of colonized species a, b, and c of anopheles culicifacies complex and anopheles stephensi were determined for 2 rodent malaria parasites plasmodium vinckei petteri and plasmodium yoelii yoelii. all the 3 members of the complex were found to support complete sporogony with varying success. controls, a. stephensi, become readily infected, with >70% developing oocysts. of the test groups, species a had the highest percentage of mosquitoes with oocysts (>25%) and sp ... | 2000 | 11191914 |
| malathion resistance and prevalence of the malathion carboxylesterase mechanism in populations of mosquito vectors of disease in sri lanka. | to determine the levels of malathion resistance and prevalence of the malathion carboxylesterase mechanism among mosquitoes in sri lanka. | 2001 | 11731814 |
| presence of anopheles culicifacies b in cambodia established by the pcr-rflp assay developed for the identification of anopheles minimus species a and c and four related species. | a polymerase chain reaction-restriction fragment length polymorphism (pcr-rflp) assay developed for identification of five species of the anopheles minimus theobald group and a related mosquito species of the myzomyia series (diptera: culicidae) was applied to morphologically identified adult female specimens collected in ratanakiri province, north-eastern cambodia. in addition to finding an. aconitus dönitz, an. minimus species a and an. pampanai büttiker & beales, some specimens showed a new r ... | 2002 | 12243235 |
| some characteristics of the larval breeding sites of anopheles culicifacies species b and e in sri lanka. | anopheles culicifacies giles, the major malaria vector in sri lanka, exists as a species complex comprising two sympatric sibling species--species b and e. species e is reported to be the major vector of plasmodium vivax and p. falciparum parasites in sri lanka, whilst species b is a poor or nonvector as in india. knowledge of the breeding habits of the two sibling species can help in designing optimal vector control strategies. hence, a survey was conducted in sri lanka to study the preferentia ... | 2005 | 16161699 |
| parasite killing in malaria non-vector mosquito anopheles culicifacies species b: implication of nitric oxide synthase upregulation. | anopheles culicifacies, the main vector of human malaria in rural india, is a complex of five sibling species. despite being phylogenetically related, a naturally selected subgroup species b of this sibling species complex is found to be a poor vector of malaria. we have attempted to understand the differences between vector and non-vector anopheles culicifacies mosquitoes in terms of transcriptionally activated nitric oxide synthase (acnos) physiologies to elucidate the mechanism of refractorin ... | 2011 | 21483693 |
| karyotypic assignment of sri lankan anopheles culicifacies species b and e does not correlate with cytochrome oxidase subunit i and microsatellite genotypes. | the identification of species b and e in the anopheles culicifacies complex in the indian subcontinent has been based on y-chromosome karyotype. since no detectable variations were previously found in dna markers commonly used for sibling species identification, further molecular characterization using cytochrome oxidase subunit i (coi) and microsatellite markers was carried out on y-chromosome karyotyped anopheles culicifacies specie b and e from unnichchai, kallady and ranawarunawa in sri lank ... | 2015 | 26071055 |
| sequencing and analysis of the complete mitochondrial genome in anopheles culicifacies species b (diptera: culicidae). | the complete mitochondrial genome sequence of anopheles culicifacial species b was sequenced in this study. the length of the mitochondrial genome is 15 330 bp, which contains 13 protein-coding genes (pcgs), 22 trna genes, two rrna genes, and a non-coding control region. the gene order and the gene composition are consistent with those previously reported for other mosquito species. the initiation codon of the pcgs complies with the atn rule except for coi using tcg and nd5 using gtg as a start ... | 2016 | 26114319 |
| x-linkage of malic enzyme in anopheles culicifacies species b. | a survey for malic enzyme (me) in laboratory strains of species a and species b of anopheles culicifacies had uncovered two electrophoretic variants, slow and fast, in two strains of species b. genetic analysis revealed the two variants to be codominant alleles segregating at a locus, me, which is sex linked. because of the xx-xy sex determining mechanism, in f1 females, two electromorphs, viz., slow and fast, were observed, whereas in males only one electromorph of maternal origin was seen. lin ... | 2003 | 3367035 |
