| mosquito and arbovirus activity during 1997-2002 in a wetland in northeastern mississippi. | the species composition and population dynamics of adult mosquitoes in a wetland near iuka, ms, were analyzed over a 6-yr period (1997-2002) and reverse transcription-polymerase chain reaction (pcr) detection rates of arboviruses determined during five of those years. blood meals of three likely vector species were identified using a pcr-based method that allows identification of the host to species. culex erraticus (dyar & knab) composed 51.9% of the population during the 6-yr period with 295 f ... | 2004 | 15185956 |
| entomopathogenic fungi for mosquito control: a review. | fungal diseases in insects are common and widespread and can decimate their populations in spectacular epizootics. virtually all insect orders are susceptible to fungal diseases, including dipterans. fungal pathogens such as lagenidium, coelomomyces and culicinomyces are known to affect mosquito populations, and have been studied extensively. there are, however, many other fungi that infect and kill mosquitoes at the larval and/or adult stage. the discovery, in 1977, of the selective mosquito-pa ... | 2004 | 15861235 |

| sex-biased avian host use by arbovirus vectors. | prevalence of arthropod-borne parasites often differs drastically between host sexes. this sex-related disparity may be related to physiological (primarily hormonal) differences that facilitate or suppress replication of the pathogen in host tissues. alternately, differences in pathogen prevalence between host sexes may be owing to differential exposure to infected vectors. here, we report on the use of pcr-based assays recognizing bird sex chromosomes to investigate sex-related patterns of avia ... | 2014 | 26064562 |
| dispersal of culex mosquitoes (diptera: culicidae) from a wastewater treatment facility. | a mark-recapture project examined dispersal and flight distances of culex mosquitoes from a wastewater treatment plant in albany, ny, during 2007 and 2008. a self-marking device was constructed to mark egressing mosquitoes with fluorescent marking powder. mosquitoes were recaptured using 30 cdc miniature light traps located within a 2.0 km radius of the marking site. a total of 13 and 10 marked culex mosquitoes were recaptured in 2007 and 2008, respectively. culex mosquitoes traveled a minimum o ... | 0 | 22308769 |
| identification and characterization of two novel rna viruses from anopheles gambiae species complex mosquitoes. | mosquitoes of the anopheles gambiae complex display strong preference for human bloodmeals and are major malaria vectors in africa. however, their interaction with viruses or role in arbovirus transmission during epidemics has been little examined, with the exception of o'nyong-nyong virus, closely related to chikungunya virus. deep-sequencing has revealed different rna viruses in natural insect viromes, but none have been previously described in the anopheles gambiae species complex. here, we d ... | 2016 | 27138938 |

| mosquito oviposition behavior and vector control. | the burden of gene transfer from one mosquito generation to the next falls on the female and her eggs. the selection of an oviposition site that guarantees egg and larval survival is a critical step in the reproductive process. the dangers associated with ephemeral aquatic habitats, lengthy droughts, freezing winters, and the absence of larval nutrition makes careful oviposition site selection by a female mosquito extremely important. mosquito species exhibit a remarkable diversity of ovipositio ... | 2016 | 27869724 |
| phylogenetic analysis and temporal diversification of mosquitoes (diptera: culicidae) based on nuclear genes and morphology. | phylogenetic analyses provide a framework for examining the evolution of morphological and molecular diversity, interpreting patterns in biogeography, and achieving a stable classification. the generic and suprageneric relationships within mosquitoes (diptera: culicidae) are poorly resolved, making these subjects difficult to address. | 2009 | 20028549 |

| Competency of reptiles and amphibians for eastern equine encephalitis virus. | Eastern equine encephalitis virus (EEEV) is endemic throughout most of the eastern United States. Although it is transmitted year round in Florida, transmission elsewhere is seasonal. The mechanism that enables EEEV to overwinter in seasonal foci remains obscure. In previous field studies, early season EEEV activity was detected in mosquito species that feed primarily upon ectothermic hosts, suggesting that reptiles and amphibians might represent overwintering reservoir hosts for EEEV. To determ ... | 2011 | 21896798 |
| winter biology of wetland mosquitoes at a focus of eastern equine encephalomyelitis virus transmission in alabama, usa. | at temperate latitudes, vectors and pathogens must possess biological mechanisms for coping with cold temperatures and surviving from one transmission season to the next. mosquitoes that overwinter in the adult stage have been proposed as winter maintenance hosts for certain arboviruses. in the cases of west nile virus (family flaviviridae, genus flavivirus) and st. louis encephalitis virus (family flaviviridae, genus flavivirus), discovery of infected overwintering females lends support to this ... | 2011 | 21936314 |
