Standardisation of Units for Assessment of Adult Disease Vector Density under Vector Control Programmes in India

Vector density is one of the most frequently used monitoring parameters entomological surveillance under any vector control programme. applications are guided by vectors or their abundance in different seasons and settings. The common vector-borne diseases viz. malaria, filaria, kala-azar, dengue, chikungunya, Zika Japanese Encephalitis (JE) have bionomics. Scientists, researchers, public health entomologists various research institutes programmes engaged studying bionomics through activities. parameter to estimate non-vector species both mosquitoes flies collection a given unit time. In malaria programme, it started as resting at specified time dawn dusk. These expressed number forms ‘per man hour’, ten hour’ ‘ten ascertain level population its increasing decreasing trend with climatic factors which may be correlated active transmission disease. minimum was evidenced has been termed ‘critical density’. Various critical densities. Many other populations but such units often lead confusion among field functionaries. This article describes significance man-hour density’, methodology practice for ages statistical method calculation. To avoid misconception, should understood that particular ‘differential density’ not absolute density.
