A cypovirus from the mosquito Culex restuans (named CrCPV) was isolated and its biology, morphology, and molecular characteristics were investigated. CrCPV is characterized by small (0.1-1.0 microm), irregularly shaped inclusion bodies that are multiply embedded. Laboratory studies demonstrated that divalent cations influenced transmission of CrCPV to Culex quinquefasciatus larvae; magnesium en...
background: epidemics of mosquito-borne viral infections such as dengue, chikungunya, west nile and rift valley fevers in neighbouring countries and risk of introduction of exotic vectors into iran have placed this country at a significant risk for these mosquito-borne diseases. methods: after the first dengue case reported in iran in 2008, active entomological surveillance of aedes albopictus ...
OBJECTIVE The western borderland between Yunnan Province, China, and Myanmar is characterized by a climate that facilitates year-round production of mosquitoes. Numerous mosquito-transmitted viruses, including Japanese encephalitis virus circulate in this area. This project was to describe seasonal patterns in mosquito species abundance and arbovirus activity in the mosquito populations. METH...
b a ckground: several important diseases are transmitted by mosquitoes. despite of the potential of the occurrence of some mosquito-borne diseases such as west nile, dirofilariasis and malaria in the region, there is no recent study of mosquitoes in west azerbaijan province. the aim of this investigation was to study the fauna, composition and dis- tribution of mosquitoes and the characteristic...
Zika virus (ZIKV) is an arthropod-borne virus (arbovirus) that recently caused outbreaks in the Americas. Over the past 60 years, this virus has been observed circulating among African, Asian, and Pacific Island populations, but little attention has been paid by the scientific community until the discovery that large-scale urban ZIKV outbreaks were associated with neurological complications suc...
ABSTRACT
 
 First Transmission Assessment Survey (TAS-1) has been carried out successfully in Donggala District. The success was supported by epidemiological aspects, including data on the presence of vectors and environment that is potential as a breeding places for mosquitoes. In order District to achieve filariasis elimination formally, it important determine existence itspotential...
Two hundred and ten isolations of West Nile virus (WNV) were obtained from 17 mosquito species in six genera in statewide surveillance conducted in Connecticut from June through October, 1999-2003. Culex pipiens (86), Culex salinarius (32), Culex restuans (26), Culiseta melanura (32), and Aedes vexans (12) were implicated as the most likely vectors of WNV in the region based on virus isolation ...
