Zika virus transmission is primarily vector-borne, mainly via Aedes mosquitoes. The virus can also be found in various body fluids and transmission by sexual contact has also been reported. Aedes aegypti, the principal vector, is found in tropical and subtropical climates and adapts well to urban areas, living in and around human habitations. The areas affected by Zika virus lie within areas af...

With no vaccine or medicine specifically designed to treat Dengue, attention naturally shifts to prevention. Minimizing the risk of the disease equates to minimizing the exposure to aedes aegypti. Getis, Morrison, Gray, and Scott conducted a spatial study of the distribution of the aedes aegypti in Iquitos, Peru, a city of about 345,000 people 120m above sea level in the Amazon basin area of Pe...

INTRODUCTION This study registers Ascogregarina spp. infection in field populations of Aedes aegypti and Aedes albopictus in a subtropical region of Brazil. METHODS Mosquito larvae collected in tires placed in four municipalities of Santa Catarina were identified morphologically and assessed for Ascogregarina sp. infection using morphological and molecular methods. RESULTS Both mosquito spe...

Cynoff 25ULV (cypermethrin 25 g/l) and Solfac UL015 (cyfluthrin 1.5% w/v) were evaluated against the sentinel sugar-fed adults and 4th-instar larvae of Aedes aegypti in a housing estate endemic of dengue in Malaysia. The impact of both pyrethroids on field populations of Aedes albopictus and Aedes aegypti larvae was monitored weekly using bottle containers. Both Cynoff 25ULV and Solfac UL015 sh...

Floodwater Aedes breeding habitats in central Kenya were sequentially flooded to determine the numbers of mosquito eggs hatching during each flooding. Approximately 90% of the larvae sampled during 4 floodings emerged during the initial flooding. The number of Aedes eggs hatching during the second flooding was lowest of all 4 floodings, and no significant differences in the amount of egg hatchi...

INTRODUCTION Aedes aegypti eggs can be collected from the water surface. METHODS Aedes aegypti oviposition from 97 field ovitraps was studied. RESULTS Of the 16,016 eggs collected, 11,439 were obtained from paddles in ovitraps and 4,577 from water. Further, 89 (91.8%) traps contained eggs on water and 22 (22.7%) traps contained eggs only on water. CONCLUSIONS In field traps, Aedes aegypti...

OBJECTIVE To describe the hematophagous activity of Ae. aegypti and Ae. albopictus in an area under control and surveillance. METHODS The study was conducted during 18 months, from April, 1993 to October, 1994, in Cosmopolis, Sao Paulo state, Brazil. Human baits were used to collect mosquitoes. The number of females captured is presented monthly by area of the city and local in the household....

BACKGROUND & OBJECTIVES A longitudinal, entomological and virological study was conducted from 2007 to 2010 in four dengue fever affected areas of Thiruvananthapuram district, Kerala to understand the risk factors involved in the dengue transmission. METHODS Aedes surveys were carried out seasonally in the selected localities both indoors and peridomestic sites. Water holding containers were ...

An Aedes survey using various larval survey methods was conducted in 12 urban housing areas and 29 vacant lands in Sibu town proper. Aedes albopictus larvae were found in all areas surveyed while Aedes aegypti larvae were present in 10 localities and 4 vacant lands. There were no significant difference in the house index, breteau and larval density index of these two Aedes (Stegomyia) species f...
