| experimental transovarial transmission of st. louis encephalitis virus by culex and aedes mosquitoes. | colonized and field-collected female culex tarsalis, infected with st. louis encephalitis, (sle) virus by intrathoracic inoculation or by feeding on a viremic host, transmitted virus to their f1 adult and/or larval progeny when reared at 18(+/- 1) degree c but not when reared at 27(+/- 1) degrees c. the minimal infection rates (mir) for different populations of cx. tarsalis ranged from 1:32 to less than 1:250 (mean = 1:121) for larval progeny and from 1:32 to less than 1:1, 989 (mean = 1:1,571) ... | 1984 | 6696174 |
| effect of rearing temperature on transovarial transmission of st. louis encephalitis virus in mosquitoes. | female aedes albopictus and aedes epactius infected by inoculation with st. louis encephalitis (sle) virus transmitted virus transovarially to their f1 progeny. with ae. epactius, minimal infection rates (mir) in f1 larvae were similar for progeny reared at 18 (+/- 1) degree c or 27 (+/- 1) degree c, whereas, mir's were significantly higher in f1 adults reared at 18 degrees c, than they were in f1 adults reared at 27 degrees c. use of different strains of sle virus appeared to influence transova ... | 1980 | 7435796 |
| sensory aspects of host location in mosquitoes. | visual, thermal and olfactory stimuli all contribute to blood meal host location in mosquitoes but olfaction is probably the dominant sensory modality used for this purpose. much attention has been devoted to the l-lactic acid receptor because it is well characterized and because its sensitivity is a major determinant of host responsiveness in the anautogenous species aedes aegypti. studies employing statistical analysis of close to 500 single unit recordings and the scanning electron microscope ... | 1996 | 8894299 |
| out of the bush: the asian bush mosquito aedes japonicus japonicus (theobald, 1901) (diptera, culicidae) becomes invasive. | the asian bush or rock pool mosquito aedes japonicus japonicus is one of the most expansive culicid species of the world. being native to east asia, this species was detected out of its original distribution range for the first time in the early 1990s in new zealand where it could not establish, though. in 1998, established populations were reported from the eastern us, most likely as a result of introductions several years earlier. after a massive spread the mosquito is now widely distributed i ... | 2014 | 24495418 |
| diversity of mosquitoes and the aquatic insects associated with their oviposition sites along the pacific coast of mexico. | the abundance, richness and diversity of mosquitoes and aquatic insects associated with their oviposition sites were surveyed along eight states of the pacific coast of mexico. diversity was estimated using the shannon index (h'), similarity measures and cluster analysis. | 2014 | 24450800 |
| pyrosequencing the midgut transcriptome of the banana weevil cosmopolites sordidus (germar) (coleoptera: curculionidae) reveals multiple protease-like transcripts. | the banana weevil cosmopolites sordidus is an important and serious insect pest in most banana and plantain-growing areas of the world. in spite of the economic importance of this insect pest very little genomic and transcriptomic information exists for this species. in the present study, we characterized the midgut transcriptome of c. sordidus using massive 454-pyrosequencing. we generated over 590,000 sequencing reads that assembled into 30,840 contigs with more than 400 bp, representing a sig ... | 2016 | 26949943 |
| genome sequence of a baculovirus pathogenic for culex nigripalpus. | in this report we describe the complete genome sequence of a nucleopolyhedrovirus that infects larval stages of the mosquito culex nigripalpus (cuninpv). the cuninpv genome is a circular double-stranded dna molecule of 108,252 bp and is predicted to contain 109 genes. although 36 of these genes show homology to genes from other baculoviruses, their orientation and order exhibit little conservation relative to the genomes of lepidopteran baculoviruses. cuninpv genes homologous to those from other ... | 0 | 11602755 |
| aedes (ochlerotatus) epactius along an elevation and climate gradient in veracruz and puebla states, méxico. | we report on the collection ofimmatures of aedes (ochlerotatus) epactius dyar & knab from artificial containers during july through september 2011 in 12 communities located along an elevation and climate gradient extending from sea level in veracruz state to high elevations (>2,000 m) in veracruz and puebla states, méxico. ae. epactius was collected from 11 of the 12 study communities; the lone exception was the highest elevation community along the transect (>2,400 m). this mosquito species was ... | 2012 | 23270151 |
| new nebraska mosquito distribution records. | larval collections in nebraska during 2000 established 2 new state distribution records for ochlerotatus epactius and anopheles perplexens and confirmed the presence of culiseta melanura, bringing the total number of mosquito species reported from nebraska to 50. fifteen new county records for 10 species are noted, including the 1st report of aedes albopictus from lancaster county, marking its westernmost collection in nebraska to date. | 2001 | 11804465 |
| morphology of long- and short-day eggs of aedes atropalpus and a. epactius (diptera: culicidae). | scanning electron micrographs are used to document differences in the shape and fine structure of long-day (16:8 [l:d] h) and short-day (8:16 [l:d] h) eggs of aedes atropalpus (coquillett) and aedes epactius dyar & knab from illinois. both shape and structural detail differed much more in a. atropalpus than in a. epactius. long-day eggs of a. atropalpus were significantly longer and narrower; their outer chorionic cells on both the ventral (upper) and lateral surfaces were significantly smaller ... | 1994 | 7815398 |
| intra-annual changes in abundance of aedes (stegomyia) aegypti and aedes (ochlerotatus) epactius (diptera: culicidae) in high-elevation communities in mexico. | we examined temporal changes in the abundance of the mosquitoes aedes (stegomyia) aegypti (l.) and aedes (ochlerotatus) epactius dyar & knab from june to october 2012 in one reference community at lower elevation (rio blanco; approximately 1,270 m) and three high-elevation communities (acultzingo, maltrata, and puebla city; 1,670-2,150 m) in veracruz and puebla states, méxico. the combination of surveys for pupae in water-filled containers and trapping of adults, using bg-sentinel traps baited w ... | 2014 | 25118405 |

| new county records of aedes aegypti and aedes epactius in colorado. | in august and september 2017, we conducted mosquito surveillance in southeastern colorado by using ovitraps and larval sampling. the aim was to determine if there were established populations of aedes aegypti and ae. albopictus in the region. a single female ae. aegypti was reared from eggs collected in la junta, co, but ae. albopictus was not detected. three other species were reared from eggs and/or larvae: ae. epactius, culex restuans, and cx. pipiens. aedes aegypti and ae. epactius were dete ... | 2019 | 31442179 |
