Diversity and seasonal densities of vector anophelines in relation to forest fringe malaria in district Sonitpur, Assam (India)

Abstract

The prevalence and bionomics of known Indian malaria vector anophelines was studied in three forest fringe villages in Sonitpur district of Assam, India. Anopheles philippinensis/nivipes (36.8%) and An. annularis (25.6%) were the most abundant of the seven vector anopheline species recorded. Densities of vector anophelines in general were high during monsoon season and low during winter months. An. dirus s.l. was the most anthropophagic (91.6%) of all the species collected whereas, An. annularis, An. fluviatilis s.l. and An. varuna were predominantly zoophagic. The highest and the lowest slide positivity rates (SPR) was recorded during monsoon (36%) and winter (12.5%) seasons, respectively. SPR was positively correlated with vector anopheline densities (r = 0.902), which itself was found to be correlated with mean minimum temperature and relative humidity (RH).

Monitoring of malaria, Japanese encephalitis and filariasis vectors

“…annularis and Anopheles jeyporiensis are malaria vectors of local importance. 13 The studies on the vectors of defence importance would help in the adoption of preventive measures thereby reducing the morbidity and mortality due to vector borne diseases in the armed forces. 7 The light trap collections from the villages around the military station revealed the mosquito density and diversity in the area.…”

“…However earlier studies indicated that these efficient vector anophelines were present in high densities in the forest fringe villages. 13 An. philippinensis/ nivipes, which probably plays a role in malaria transmission in the region 16 was the predominant species among the known malaria vectors.…”

Larvicidal, super hydrophobic and antibacterial properties of herbal nanoparticles from Acalypha indica for biomedical applications

“…[3][4][5] The herbal nanoparticle treated materials are known in the eld of biomedical applications for their exotic properties, e.g., non-toxic, mosquito repellent, hydrophobic, ultraviolet protection (UV) and antimicrobial action. [6][7][8][9] Acalypha indica (A. indica) is a common weed that belongs to the Euphorbiaceae family. It grows in common farmlands, gardens and uncultivated lands.…”
