| first record of culex (culex) coronator in louisiana, usa. | the 1st confirmed record of culex coronator for louisiana was made at fort polk, la, from carbon dioxide-baited light trap and gravid trap collections performed from april to october 2004. in addition to the new record, 17 mosquito species in 5 genera (aedes, anopheles, coquillettidia, culex, and psorophora) were collected. collection-site and species distribution data are included. | 2005 | 16506572 |

| temporal variations of microbiota associated with the immature stages of two florida culex mosquito vectors. | microbiota associated with mosquito vector populations impact several traits of mosquitoes, including survival, reproduction, control, and immunity against pathogens. the influence of seasonal variations and mosquito species on mosquito gut microbiota is poorly understood. we sought to determine whether the mosquito microbiota associated with immature stages of two congeners (culex coronator and culex nigripalpus) differ temporally and between the two species. using high throughput 16s rrna gene ... | 2017 | 28492989 |
| first record of culex coronator in shelby county, tennessee. | culex coronator has been identified in shelby county, tn, for the first time as an established species. this is an important discovery since the range of cx. coronator is unknown in tennessee and it has been found positive for west nile virus. larvae and an adult were discovered during routine surveillance. larvae were collected at 9 different locations, while the 1 adult captured was at the 10th isolated location. | 2017 | 29369022 |
| first record of culex coronator in virginia, with notes on its rapid dispersal, trapping methods, and biology. | culex coronator is a neotropical mosquito species that was first described in trinidad in the early 20th century. since then, the species has been discovered from patagonia to the southern usa. a single adult female cx. coronator was collected on november 1, 2016, in suffolk, va, in a bg-sentinel 2® trap during routine mosquito surveillance. this represents the 1st record of this species in the state of virginia and the northernmost record in the usa. based on male specimens examined from texas ... | 2017 | 28854110 |
| highlights of medical entomology 2018: the importance of sustainable surveillance of vectors and vector-borne pathogens. | the theme of the 2018 entomological society of america, entomological society of canada, and entomological society of british columbia joint annual meeting was crossing borders: entomology in a changing world. following the theme of the meeting, papers selected for the 2018 'highlights of medical entomology' included reports of expanded ranges for aedes albopictus (skuse) (diptera: culicidae), aedes japonicus japonicus (theobald) (diptera: culicidae), culex coronator dyar and knab (diptera: culi ... | 2019 | 31505669 |
| first report of culex flavivirus infection from culex coronator (diptera: culicidae), colombia. | flaviviruses are important pathogens for humans and animals (dengue viruses, yellow fever virus, zika virus and west nile virus). culex flavivirus (cxfv) is an insect-specific virus of the genus flavivirus, detected in a wide variety of mosquito species. | 2019 | 30606229 |
| first record of aedes japonicus japonicus in oklahoma, 2017. | in spring 2017, mosquito larvae were collected from 25 sites across eastern oklahoma as part of a zika virus vector surveillance effort. aedes japonicus japonicus larvae were collected from horse troughs at 2 sites in ottawa county, ok. identification was made using 1 larva stored in 70% ethanol and 3 adult females reared from the larvae. another invasive mosquito species, culex coronator, was detected at 2 different sites, adding 2 additional counties to the 9 where the species had been previou ... | 2018 | 31442116 |
| size of openings in water-holding containers: impact on oviposition by culex (culex) mosquitoes. | to assess how a grate covering a catch basin impacts oviposition by culex mosquitoes, a field study was conducted in south florida using containers with two types of covers, with openings of equal area, but different configurations. one opening mimicked a catch basin grate with 16 small openings, while the other cover had just one large opening. the number and presence of egg rafts in six of each container and cover combination was recorded over 18 nights at two field sites, consisting of a wast ... | 2019 | 31438538 |
| distribution of culex coronator in texas. | the distribution of culex coronator dyar and knab by county in texas was updated by combining data from peer-reviewed literature, military and government reports, and university and private collections, and by collecting specimens from counties where data had not been reported. with 254 counties in texas, the initial collection effort was focused on counties east of us highway 277, which runs from val verde county on the us and mexico border to wichita county on the texas and oklahoma border. th ... | 2019 | 31442181 |
