| [impact of pesticide use on the density of anopheles anthropophagus and malaria incidence]. | to investigate the impact of the application of chemical pesticides on the distribution of anopheles anthropophagus in rice fields and the malaria incidence. | 2012 | 23072140 |
| [impact of different temperatures on development of anopheles anthropoghagus in jiangsu province]. | to observe the development and breeding of anopheles anthropophagus in jiangsu province under different temperatures, so as to provide theoretical evidence for malaria epidemiology research and vector control. | 2011 | 22263515 |
| chemical composition and larvicidal effects of essential oil of blumea martiniana against anopheles anthropophagus. | to determine chemical composition of the hydrodistilled essential oil of blumea martiniana, and to evaluate its larvicidal activity against anopheles anthropophagus, the natural vector of malaria. | 2011 | 21771679 |
| chemical composition and larvicidal activity of blumea densiflora essential oils against anopheles anthropophagus: a malarial vector mosquito. | blumea densiflora, an edible and medicinal plant, is chiefly distributed in southeast asia and south asia. essential oils extracted by steam distillation from b. densiflora were investigated for their chemical composition and larvicidal activity against anopheles anthropophagus, the primary vector of malaria in china and other east asian countries. totally, 46 compounds were identified by gas chromatography and mass spectroscopy. the major chemical compounds identified were borneol (11.43%), ger ... | 2011 | 21556689 |
| [historical review on the classification and rectification of anopheles anthropophagus to an. lesteri in china]. | this paper deals with the taxonomic status and specific names of anopheles anthropophagus and an. lesteri, the important malaria transmitting vector in china. based on a historical review of the literature recorded from the country, substantial evidence from morphological and molecular biological studies gives reason to convince that an. anthropophagus is a synonym of an. lesteri. a resurrection of the specific name of an. lesteri barisas et hu, 1936 brooks no delay. | 2008 | 19160973 |
| [studies on the components of trace elements and macro elements in hemolymph of anopheles anthropophagus]. | the elements in hemolymph of an. anthropophagus were determined by icap. there were 18 kinds of trace elements such as fe,zn,cu,mn,cr,mo,co,ni,v,sr,b,al,ba,zr, cd,pb,ga,li and 6 kinds of macro elements such as ca,mg,k,na,s,p in the hemolymph of the mosquito. the contents of the macro elements and fe in hemolymph of newly emerged mosquitoes were significantly higher than those of mosquitoes after taking blood meal, whereas zn and al were lower. comparing elements in hemolymph of an. anthropophagu ... | 1994 | 8044900 |
| [dna probe for identification of sibling species of anopheles sinensis and anopheles anthropophagus]. | genomic dna libraries of anopheles sinensis and anopheles anthropophagus were constructed. the positive clones suitable for discrimination sibling species of an. sinensis and an. anthropophagus were screened and a clone from an. sinensis dna library was selected and the insert dna was used as a dna probe to test dot blot of genomic dna from an. sinensis and an. anthropophagus. the results showed that the dna probe hybridized with all stages of an. sinensis dna, but had very weak hybridization si ... | 1992 | 1303333 |
| [restriction fragment length differences (rflds) of genomic dna from different geographical strains of anopheles sinensis and anopheles anthropophagus]. | total dna was extracted from three geographical strains of anopheles sinensis and two geographical strains of anopheles anthropophagus and digested respectively with three restriction endonucleases (bgl ii, hae iii and pst i). the restriction fragment length differences (rflds) of repetitive dna detected after agarose gel electrophoretic separation and ethidium bromide staining were compared among the above-mentioned geographical strains of both an. sinensis and an. anthropohagus. the results in ... | 1990 | 1982859 |
| [comparative studies on several biochemical indices of anopheles anthropophagus and anopheles sinensis]. | proteins, sugars and esterase isoenzymes of an. anthropophagus and an. sinensis were compared by ief and two dimensional gel electrophoresis. the results show that there are some differences in the electrophoretic patterns between an. anthropophagus and an. sinensis. the glycoprotein, lipid protein, glycolipidprotein, protein, polysaccharide and esterase isoenzymes showed 10, 0, 6, 14, 2 and 13 bands in an. anthropophagus; 10, 1, 5, 16, 3 and 15 in an. sinensis. there exist 234 and 240 polypepti ... | 1989 | 2633890 |
