| vector competence of california mosquitoes for california encephalitis and california encephalitis-like viruses. | mosquitoes collected from coastal, inland valley, and alpine locations in california were evaluated for their experimental vector competence for two viruses in the california serogroup (bunyaviridae:bunyavirus). aedes squamiger, a coastal salt marsh mosquito, was an efficient vector of a california encephalitis (ce)-like virus isolated from its habitat (89% of the pledget-fed females became infected and 61% transmitted virus). aedes dorsalis, a coastal mosquito, and ae. melanimon, an inland vall ... | 1992 | 1360192 |
| occurrence and evolutionary significance of a california encephalitis-like virus in aedes squamiger (diptera: culicidae). | more than 12,000 aedes increpitus dyar and 4,600 aedes squamiger (coquillett) were tested for the presence of arboviruses to test the hypothesis that there is a coevolutionary relationship between aedes (ochlerotatus) mosquitoes and california serogroup viruses. five strains of a california encephalitis-like virus were isolated from adults reared from larvae of ae. squamiger collected in january 1989 from a coastal salt marsh at morro bay, san luis obispo county, california. viruses were isolate ... | 1991 | 1941932 |
| geographic distribution and serologic and genomic characterization of morro bay virus, a newly recognized bunyavirus. | more than 75,000 immature mosquitoes in three genera were collected from coastal california, reared to the adult stage, and tested for virus by plaque assay in vero cell cultures. twenty-six strains of morro bay (mb) virus, a newly recognized member of the california (cal) serogroup, were isolated from aedes squamiger, a pestiferous salt marsh mosquito species restricted to intertidal salt marshes in coastal california and baja california. the geographic distribution of the isolates was 10 from ... | 1996 | 8686772 |
| ecology of mosquitoes and lack of arbovirus activity at morro bay, san luis obispo county, california. | during 1994-95, totals of 17,656 adult females and 111,104 adults reared from field-collected immatures comprising 19 species in 4 genera of mosquitoes were collected from morro bay estuary and surrounding environs in san luis obispo county, california. aedes dorsalis was the dominant summer mosquito, whereas aedes squamiger and ae. washinoi were abundant during winter and early spring. host-seeking culex tarsalis were collected infrequently, even though immatures were collected frequently from ... | 1996 | 9046476 |
| influence of temperature and concentration of vectobac on control of the salt-marsh mosquito, ochlerotatus squamiger, in monterey county, california. | laboratory susceptibility bioassays were conducted to determine the efficacy of vectobac tp (bacillus thuringiensis var. israelensis [bti]) at different concentrations and temperatures against the salt-marsh mosquito ochlerotatus squamiger. bioassays on late 3rd- and early 4th-stage larvae, read at 72 h and 14 degrees c produced an ld90 of 0.223 mg/liter, whereas more than double this dose was required to produce similar mortality at 6 degrees c. a field trial in the winter of 2001-02 of an aeri ... | 2004 | 15264626 |
| vector-host interactions governing epidemiology of west nile virus in southern california. | southern california remains an important focus of west nile virus (wnv) activity, with persistently elevated incidence after invasion by the virus in 2003 and subsequent amplification to epidemic levels in 2004. eco-epidemiological studies of vectors-hosts-pathogen interactions are of paramount importance for better understanding of the transmission dynamics of wnv and other emerging mosquito-borne arboviruses. we investigated vector-host interactions and host-feeding patterns of 531 blood-engor ... | 2010 | 21118934 |
| north american wetlands and mosquito control. | wetlands are valuable habitats that provide important social, economic, and ecological services such as flood control, water quality improvement, carbon sequestration, pollutant removal, and primary/secondary production export to terrestrial and aquatic food chains. there is disagreement about the need for mosquito control in wetlands and about the techniques utilized for mosquito abatement and their impacts upon wetlands ecosystems. mosquito control in wetlands is a complex issue influenced by ... | 2012 | 23222252 |
| an assessment of mosquito production and nonchemical control measures in structural stormwater best management practices in southern california. | a 3-year study was conducted to assess mosquito production in structural stormwater best management practices (bmps) installed by the california department of transportation in san diego and los angeles counties. thirty-seven bmps were monitored weekly for presence and relative abundance of immature mosquitoes and for conditions conducive to mosquito production. species identified were aedes squamiger, anopheles franciscanus, an. hermsi, culex quinquefasciatus, cx. stigmatosoma, cx. tarsalis, cu ... | 2008 | 18437817 |
| redescription of the pupae of ochlerotatus dorsalis and ochlerotatus squamiger. | the pupae of ochlerotatus dorsalis and oc. squamiger are completely described and illustrated for the first time. considering the entire pupal morphology, characters to separate the 2 pupae are discussed. | 2011 | 21805841 |
