Dengue is a vector-borne disease caused by dengue virus. According to the recent report of CDC that one-third population of the world are at high risk with Dengue fever. The prevalence of the dengue hemorrhagic fever was found more in tropical and sub-tropical regions of the world. Aedes mosquitoes was reported as the main cause of transmission of dengue virus. So the current study was planned ...

Background: Aedes aegypti is the main vector of the yellow fever and dengue virus. This mosquito has become the major indirect cause of morbidity and mortality of the human worldwide. Dengue virus activity has been reported recently in the western areas of Saudi Arabia. There is no vaccine for dengue virus until now, and the control of the disease depends on the control of the vector. Objectiv...

The genus Flavivirus, family Flaviviridae, includes a number of important arthropod-transmitted human pathogens such as dengue viruses, West Nile virus, Japanese encephalitis virus and yellow fever virus. In addition, the genus includes flaviviruses without a known vertebrate reservoir, which have been detected only in insects, particularly in mosquitoes, such as cell fusing agent virus, Kamiti...

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 ae...

Dengue is an infection that is carried by Aedes mosquitoes (Diptera: Culicidae) and can cause severe disease in peoples living in tropics. It is capable to cause headaches, pain and rash, and in other harsh types, may cause internal bleeding and then mortality of the patient. Currently, there is no vaccine for the treatment of dengue sickness and the most widely used methods for control of dise...

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 To determine the effectiveness of using sticky traps and the NS1 dengue antigen kit for the surveillance of Aedes mosquitoes for dengue control. METHODS Apartments were selected in a dengue-endemic area, and sticky traps were set to capture adult Aedes mosquitoes. NS1 dengue antigen kit was used to detect dengue antigen in mosquitoes, and positive mosquitoes were serotyped using rea...

INTRODUCTION We analyzed the vertical and monthly distributions of culicid species in the gallery forest of Brasília National Park, with an emphasis on the potential vectors of yellow fever (YF). METHODS Between September 2010 and August 2011, mosquitoes were captured on the ground and in the canopy of the forest for five consecutive days per month, from nine to 15 hours. The mosquitoes were ...

The repellent effect of Lantana camara flowers was evaluated against Aedes mosquitoes. Lantana flower extract in coconut oil provided 94.5% protection from Aedes albopictus and Ae. aegypti. The mean protection time was 1.9 h. One application of Lantana flower can provide more than 50% protection up to 4 h against the possible bites of Aedes mosquitoes. No adverse effects of the human volunteers...

In this paper we present a model to estimate the density of aedes mosquitoes in a community affected by dengue. The method consists in fitting a continuous function to the incidence of dengue infections, from which the density of infected mosquitoes is derived straightforwardly. Further derivations allow the calculation of the latent and susceptible mosquitoes' densities, the sum of the three e...
