A study was conducted to compare responses of male and female Aedes aegypti (Linn.) and Aedes taeniorhynchus (Wiedemann) to 9 olfactory repellents in the World Health Organization insecticide irritability test system. An irritant insecticide (permethrin) and a control were included for comparison. Aedes aegypti exhibited significantly more takeoffs than Ae. taeniorhynchus, and female mosquitoes...
The spatial distribution of Aedes aegypti and Aedes albopictus in environmental and geographical zones, e.g., urban-rural, coastal-mountainous, and north-south, was investigated throughout Vietnam. Immature stages were collected from used tires along roads. The effects of regions, seasons, and the degree of urbanization on the density and the frequency were statistically analyzed. Aedes aegypti...
The emerging bunyavirus Rift Valley fever virus (RVFV) is transmitted to humans and livestock by a large number of mosquito species. RNA interference (RNAi) has been characterized as an important innate immune defense mechanism used by mosquitoes to limit replication of positive-sense RNA flaviviruses and togaviruses; however, little is known about its role against negative-strand RNA viruses s...
a a i o c w n c f t P s i s t t c e The original isolation of the Zika virus (ZIKV), a Flavivirus member of the Flaviviridae family, was obtained in 1947 from the blood of a febrile rhesus monkey exposed at the Zika forest near Lake Victoria, in the outskirts of Entebbe, the capital of Uganda.1 ZIKV was also isolated from wild mosquitoes in the same area and later periodic human febrile cases w...
Keys to the adult females and 4th instar larvae of the mosquitoes of Greece are presented. In all, 53 species in 7 genera are included. Also, Aedes albopictus is added because of the potential for its introduction into Greece.
We isolated a strain of Zika virus, MB16-23, from Aedes aegypti mosquitoes collected in Miami Beach, Florida, USA, on September 2, 2016. Phylogenetic analysis suggests that MB16-23 most likely originated from the Caribbean region.
The gonotrophic cycle of mosquitoes conditions the frequency mosquito-human contacts. knowledge this important phenomenon in mosquito life is a fundamental element epidemiological analysis communicable disease such as mosquito-borne diseases.In work, we analyze deterministic model complete which takes into account principal phases female mosquitoes' cycle, and Sterile Insect technique combined ...
Introduction As part of a statewide effort to enhance surveillance for Aedes spp. mosquitoes (1,2) the Office of Border Health (OBH) took the lead in providing technical assistance on surveillance in counties bordering Mexico. In 2016, OBH sought ways to enhance surveillance in a wider geographic area. Trap locations closer to the border were established as a priority, given high amount of traf...
BACKGROUND Dengue virus is spread in tropical areas of the world and is the causative agent of dengue fever and dengue hemorrhagic fever. It is horizontally transmitted to humans by infected Aedes mosquitoes, but it is also able to be vertically or transovarially transmitted to insect progeny. OBJECTIVE In this work, we analyzed the vertical transmission of dengue virus in Aedes aegypti mosqu...
BACKGROUND The population of mosquitoes is mainly influenced by the biotic and abiotic factors. Although Aedes aegypti was reported until 1960's in the Punjab, Pakistan, the population has increased dramatically since 2009 and caused severe epidemics in 2011 due to heavy floods and rains. Thus, this study was carried out to know the effect of biotic and abiotic factors on the population of Aede...
