the first records of anopheles fluviatilis resistance to ddt was reported in 1963 from india and to dieldrin from eastern saudi arabia in 1959. in southern iran, antimalaria measures began in 1950 and up to 1957 the area was under ddt residual house spraying at the rate of 2g /m2 one round/year. during 1958-59 dieldrin was used at 0.5 g/m2, 1or 2 rounds/year was applied in the lowland areas. in...

BACKGROUND This study was undertaken in two Primary Health Centers (PHCs) of malaria endemic district Jabalpur in Madhya Pradesh (Central India). METHODS In this study we had investigated the relative frequencies of the different anopheline species collected within the study areas by using indoor resting catches, CDC light trap and human landing methods. Sibling species of malaria vectors wer...

(?) At sundown there is a strong attraction to light, and most mosquitoes leave the house at this time. There is no similar reaction at dawn. (c) Marking and other experiments show that there is a considerable daily turn-over of the population in houses. (d) About 90 per cent of blood feeding takes place after midnight. After oviposition, A. minimus returns for another blood meal on the same ni...

BACKGROUND & OBJECTIVE Though the relationship between mosquito density and transmission of malaria in different regions of the country is known, no studies are available on the relationship between mosquito catches and malaria cases in Kalsi area of Dehradun district in Uttaranchal. Hence, the present study was done to evaluate the role of anopheline mosquitoes catches and prevalence of malari...

BACKGROUND Use of bed-net continues to offer potential strategy for malaria prevention in endemic areas. Local communities are indispensable during design and implementation stages. METHODS A cross-sectional study of 192 randomly selected inhabitants was carried out in malarious zone, Siahoo direstrict, Hormozgan Province, southern Iran. In addition, we monitored human landing periodicity of ...

BACKGROUND AND OBJECTIVES Epidemiology and transmission of malaria vary within the tribal areas with the variation in topography, forest cover and type of forest. For the control of disease, understanding of the dynamics of transmission in the varied ecological situation is essential. This study was carried out in the two distinct tribal areas- Baiga Chak (thick forested area) of Dindori distri...

Anopheles minimus (Diptera : Culicidae) has been reported as a principal malaria vector in district Nainital1. An. fluviatilis and An. culicifacies (Diptera: Culicidae) were later incriminated as malaria vectors and An. minimus was reported virtually absent2–4. Recently, in forest ecotype, An. fluviatilis has been incriminated as malaria vector and its sibling species ‘S’, which is a potential ...
