| differential selection of malathion resistance in anopheles culicifacies a and b (diptera: culicidae) in haryana state, india. | in november 1989, for the first time after the introduction of malathion spray in 1982, increased densities of anopheles culicifacies giles s.l. were observed in chhatera and barota, two villages in halalpur block in sonepat district, haryana state, india. in bioassay tests against the diagnostic dose of malathion (5% for 1 h), 41-47% of mosquitoes survived. an culicifacies populations in this area comprise two sibling species, a and b. differential malathion resistance was observed; in species ... | 1992 | 1495027 |
| occurrence of anopheles culicifacies species a in iran. | polytene chromosome preparations of the ovarian nurse cells of anopheles culicifacies females collected in 6 different parts of baluchistan, iran, during september-october 1987 and may-june 1988 revealed the existence of species a in this country. the chromosome arms are homosequential with those of species a of india. this report confirms the distribution of species a in iran. | 1991 | 1895096 |
| susceptibility of anopheles culicifacies species a and b to plasmodium vivax and plasmodium falciparum as determined by immunoradiometric assay. | we have used a two-site immunoradiometric assay and species-specific antisporozoite monoclonal antibodies to determine the relative roles that sibling species a and b of the anopheles culicifacies complex play in malaria transmission in western uttar pradesh, india. the results unequivocally establish species a as the primary vector of both plasmodium vivax and p. falciparum in this area. our results indicate active transmission of p. vivax from may to october and of p. falciparum from august to ... | 1988 | 3068854 |
| host feeding patterns of anopheles culicifacies species a and b. | countercurrent immunoelectrophoresis was used to assay bloodmeals to determine the host specificity of anopheles culicifacies species a and b, collected from areas in delhi, uttar pradesh and bihar. results indicated the predominantly zoophagic nature of species a and b with a relatively higher degree of anthropophagy for species a. further, the human blood index was found to be related to the proportion of human and cattle population in an area. this study is significant because, of the two spe ... | 1988 | 3199114 |
| vector incrimination studies and observations on species a and b of the taxon anopheles culicifacies in pakistan. | studies on anopheline mosquitoes in selected villages of punjab province, pakistan have incriminated anopheles culicifacies species a as the primary malaria vector. although an. stephensi and an. subpictus showed higher immediate gut infection rates, estimations of relative abundance, age structure and survivorship, and observations of late gut and salivary gland infection rates suggested that neither species was a major vector in these villages. a survey of an. culicifacies populations detected ... | 1984 | 6390803 |
| presence of two alternative kdr-like mutations, l1014f and l1014s, and a novel mutation, v1010l, in the voltage gated na+ channel of anopheles culicifacies from orissa, india. | knockdown resistance in insects resulting from mutation(s) in the voltage gated na+ channel (vgsc) is one of the mechanisms of resistance against ddt and pyrethroids. recently a point mutation leading to leu-to-phe substitution in the vgsc at residue 1014, a most common kdr mutation in insects, was reported in anopheles culicifacies-a major malaria vector in the indian subcontinent. this study reports the presence of two additional amino acid substitutions in the vgsc of an an. culicifacies popu ... | 2010 | 20509922 |
| triple insecticide resistance in anopheles culicifacies: a practical impediment for malaria control in odisha state, india. | in odisha state, the control of malaria vectors has become dependent on synthetic pyrethroids, which are used for treatment of all approved long-lasting insecticidal nets (llins). the vast use of just one class of insecticide has led to the problem of resistance to insecticides in malaria vectors. one of the major malaria vectors in odisha state is anopheles culicifacies giles. the aim of this study was to determine the resistance status of an. culicifacies to deltamethrin, a synthetic pyrethroi ... | 0 | 26905243 |
| analysis of population genetic structure of indian anopheles culicifacies species a using microsatellite markers. | anopheles culicifacies sensu lato is an important vector of malaria in southeast asia contributing to almost 70% of malaria cases in india. it exists as morphologically similar sibling species a, b, c, d and e with varied geographical distribution patterns. vector control measures have been difficult for this important vector as the sibling species have developed varying levels of resistance to the currently used insecticides. in view of the importance of this vector, we developed and validated ... | 2013 | 23742032 |
| laboratory studies on mosquito larvicidal efficacy of aqueous & hexane extracts of dried fruit of solanum nigrum linn. | aqueous and organic solvent extracts of plants/plant parts were effective in killing the mosquito larvae. comparative efficacy of the aqueous and hexane extracts of dried fruit of solanum nigrum was tested against five laboratory colonized strains of mosquito species, namely anopheles culicifacies species a, an. culicifacies species c, an. stephensi, culex quinquefasciatus and aedes aegypti to assess the possibility for use of these extracts for their control. | 2009 | 19700805 |
| evaluation of tribulus terrestris linn (zygophyllaceae) acetone extract for larvicidal and repellence activity against mosquito vectors. | acetone extracts of leaves and seeds from the tribulus terrestris (zygophyllaceae) were tested against mature and immature different mosquito vectors under laboratory condition. the extract showed strong larvicidal, properties 100 per cent mortality in the 3rd-instar larvae was observed in the bioassays with an. culicifacies giles species a, an. stephensi liston, culex quinquefasciatus say and aedes aegypti linn, against 200 ppm of the leaf acetone extract and 100 ppm seed acetone extract. the l ... | 2008 | 19579717 |
| identification, characterization and analysis of expression of gene encoding carboxypeptidase a in anopheles culicifacies a (diptera: culicidae). | carboxypeptidases are the digestive enzymes which cleave single amino acid residue from c-terminus of the protein. digestive carboxypeptidase a gene regulatory elements in insects have shown their efficiency to drive midgut specific expression in transgenic mosquitoes. however no endogenous promoter has been reported for indian malaria vector anopheles culicifacies which is major vector in indian subcontinent. here we report cloning of carboxypeptidase a gene in the an. culicifacies a including ... | 2014 | 24910441 |
