To enhance the effectiveness of an arbovirus monitoring program, we evaluated a commercially available device for sampling resting vector mosquitoes. Diverse Anopheles, Culiseta, and Culex mosquitoes were taken in these nestable fiber pots. The pots sample about as many Culiseta melanura mosquitoes per device as do conventional resting boxes, but fewer than do boxes fitted with expanded frames....

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...

background : the aim of the current study was to develop a marking technique as an internal marker to mark post blood meal mosquitoes by using stable phosphate isotope 32 p and determine the optimal concentration of it. methods : an isotonic physiological saline solution, containing different concentration of radioactive isotope 32 p-labeled disodium phosphate (na 2 h 32 po4) was injected into ...

In China, the prevention and control of Zika virus disease has been a public health threat since the first imported case was reported in February 2016. To determine the vector competence of potential vector mosquito species, we experimentally infected Aedes aegypti, Ae. albopictus, and Culex quinquefasciatus mosquitoes and determined infection rates, dissemination rates, and transmission rates....

 pyrethroid-impregnated bednets have been shown to be one of the most promising tools that have emerged in recent years to control malaria.mosquito may be physically irritated by pyrethroid reducing the time searching for blood meals,or driving them away.permethrin impregnated nets also may deter a proportion of mosquitoes from entering houses.irritant effect of nets treated with 200 mg and 500...

If it feels like you attract mosquitoes, are on to something. Females of most mosquito species need consume blood produce eggs, and they use specialized senses scope out their next snack. The saliva leave behind after “taking a bite” can cause anything from little itching painful bumps fever. These thirsty insects ability detect carbon dioxide, odor molecules, heat find food. In this article, w...

b a ckground: a field study on diversity and distribution of anophelines currently present in a past endemic malaria area of spain was carried out in order to identify possible risk areas of local disease transmission. m e t hods: multiple larval sites were sampled from june to october of 2011 in the region of somontano de barbastro (northeastern spain). the sampling effort was fixed at 10 minu...

Mosquitoes use chemical codes to locate and discriminate among vertebrate hosts obtain a blood meal. Recent advances have allowed for the identification of used by mosquitoes humans from other hosts. Humans are incidental “dead-end” West Nile virus, which is maintained in an enzootic cycle, primarily through its transmission between infected birds Culex mosquitoes. Host-seeking attracted odor c...

Toxorhynchites spp. mosquitoes are recognised as potential biological control agents of pest and vector species of mosquito. There have been many attempts to use them for this purpose since the beginning of the twentieth century, although with relatively low levels of success, which has been attributed to a lack of knowledge of the general biology of Toxorhynchites mosquitoes. Increasing resist...

The alphaviruses o'nyong nyong virus (ONNV) and chikungunya virus (CHIKV) provide a unique system to study the viral genes involved in vector specificity. ONNV infects both anopheline and culicine mosquitoes, whereas CHIKV infects only culicine mosquitoes. In this study, chimeric viruses were constructed that contained genes from both ONNV and CHIKV. These chimeras and previously described full...
