| incrimination of anopheles dirus as a vector of malaria in dibrugarh district, assam. | anopheles nigerrimus, a. vagus, a. dirus, a. karwari and a. kochi were the most abundant species among 12 anopheline species collected during the course of entomological studies carried out from july to september, 1988 in an area endemic for malaria under tengakhat phc of dibrugarh district, assam. sporozoites were detected in the salivary glands of one specimen of a. dirus, peyton & harrison (a. balabacensis) which constituted about 18.11 per cent of the total anopheline collection. | 1989 | 2699591 |
| seasonal prevalence of anopheles dirus and malaria transmission in a forest fringed village of assam, india. | seasonal abundance of anopheles dirus (s.l.) and malaria prevalence in an isolated forest fringed village was monitored at monthly intervals during august 1995 to july 1996. an. dirus was the only vector species detected during the study period. its density pattern showed distinct seasonality with the peak occurring in the month of july and very low number during cool dry months. positive correlation (r = 0.721) was found between the density of an. dirus and the amount of rainfall occurring two ... | 1997 | 9519567 |
| breeding and day resting habitats of anopheles dirus in assam, india. | longitudinal surveys at monthly frequency were carried out during 1995-1996 in a forest fringed village of district dibrugarh, assam to decipher the breeding and day resting habitats of anopheles dirus. it regularly bred in small, shallow, rain filled, transient, shady or partly shady puddles/ground pools in the rainy months and in the perinneal streams in the adjoining forest of the village during dry months. in pools, the degree of interspecific association (0.238 +/- 0.174) and index of assoc ... | 1997 | 9561617 |
| larval ecology and mosquito fauna of upper brahmaputra valley, northeast india. | ninety-one mosquito species in 15 genera were collected from 22 habitat types of upper brahmaputra valley in assam and bordering areas of arunachal pradesh. nineteen species have been recorded for the first time in assam including seven first records from the northeast region and three first country records. jaccard's coefficient was used to quantify the similarity between 13 different geographical localities surveyed on the basis of their mosquito fauna. group average sorting (upgma) cluster an ... | 1998 | 10497839 |

| physico-chemical characteristics of breeding habitats of anopheles dirus (diptera:culicidae) in assam, india. | larval ecology of anopheles dirus, the main vector of forest malaria in north-eastern region of india, was studied in relation to physico-chemical characteristics of its breeding habitats in a rain forest area of assam, india. shady stream side pools, positive for the breeding of an. dirus, had significantly higher amounts of total hardness (p < 0.024) in comparison to negative pools of similar type. when compared with an. dirus negative breeding habitats, in hot-wet as well as in cool-dry seaso ... | 2002 | 12617325 |
| estimation of vectorial capacity of anopheles dirus (diptera: culicidae) in a forest-fringed village of assam (india). | to estimate the vectorial capacity of anopheles dirus, the main vector of forest malaria in the northeastern region of india, in order to gain an understanding of entomological factors related to malaria transmission in forest-fringe areas of assam, india, an isolated village in the tropical rain forest-fringed area in the district of dibrugarh, assam, under the influence of an. dirus alone was studied. data on various entomological variables required for computation of the vectorial capacity we ... | 2001 | 12653151 |
| malaria control in a forest camp in an oil exploration area of upper assam. | assam, in north-east india, is extremely rich in hydrocarbon deposits and the oil industry is the major contributor to its economy. a large number of oil fields and related installations in assam are located in forest areas or on their fringes where malaria is a serious problem among field staff and security personnel, adversely affecting oil production. we carried out an operational research study for one year in a forest-based industrial security camp of dibrugarh district and developed an eff ... | 2003 | 12929855 |
| molecular characterization and species identification of the anopheles dirus and an. minimus complexes in north-east india using r-dna its-2. | the sibling species composition of the anopheles minimus and anopheles dirus complexes is poorly known in the highly malarious north-eastern region of india where these two vector taxa are accountable for most of the malaria transmission among 30.7 million inhabitants. prevalent members of these two complexes in this part of india were identified using sequences for the second internal transcribed spacer (its2) of ribosomal dna. anopheles baimaii (species d) of the an. dirus complex and an. mini ... | 2006 | 17118324 |
| spatial distribution and r-dna second internal transcribed spacer characterization of anopheles dirus (diptera: culicidae) complex species in north-east india. | the identity and distribution of the prevalent member species of the anopheles dirus complex mosquitoes in the north-eastern region of india was investigated in a cross-sectional study. we altogether collected 267 individuals of an. dirus s.l. from 27 forested/forest fringed locations spread across the seven north-eastern states, identified the species using a ribosomal dna (r-dna) second internal transcribed spacer (its2) based allele specific polymerase chain reaction (aspcr) method and sequen ... | 2010 | 20074537 |
