Inhibition of Culex pipiens (L.) (Diptera: Culicidae) emergence with methoprene
… formulated as Altosid® SR-10 was tested against Culex pipiens L. under simulated field conditions and against Aedes aegypti (L.) in the laboratory. Rates from 0.0027 to 0.27 1b. a.i./A resulted in 90 to 100% emergence inhibition. In the same tests, diflubenzuron (1-(4 chlorophenyl)-3-(2, …

Overwintering Biology of Culex Pipiens Linnaeus (Culicidae) in East-Central Illinois
Culex pipiens was the only species collected from the Champaign-Urbana, overwintering site. Temperature was the key factor in resting site choice by these females, with most found in the coldest areas of the site throughout the overwintering season. Furthermore, results suggested that temperature …

Genomic analysis of the diapause program in the West Nile virus vector Culex pipiens.
The Culex pipiens complex of mosquitoes is a major vector for several pathogens responsible for infectious human diseases including West Nile virus in North America. With the growth of the American population, the prevalence of vector-borne diseases has become an increasing threat to human safety. …

Studies on Host-Seeking Behavior and Differential Chemosensory Gene Expression in Above- and Below-ground Culex Pipiens
Culex pipiens is the primary vector of WNV. It exists as two bioforms which can hybridize in nature. I characterized the behavioral and genetic variation across eight populations collected from above- and below-ground habitats. Three of the five above-ground populations had hybrid ancestry in our …

Vector competence of Ochlerotatus trivittatus (Coquillett), Aedes albopictus (Skuse), and Culex pipiens (L) (Diptera: Culicidae) for West Nile virus
… with titers higher than 1010.0 CID50s/ml. Culex species of mosquitoes are the primary amplifying vectors. Many species of mammals are also susceptible to WNV but develop viremias that seldom exceed 105.0 CID50s/ml. Mammals may play a significant role in WNV ecology if mosquitoes that feed …

Analysis of the feeding behaviour of the mosquito Culex pipiens L. (Diptera: Culicidae) in relation to West Nile virus
… Virus (WNV) transmission by its mosquito vector, Culex pipiens and to elucidate how Cx. pipiens and WNV are intertwined. The first few sections of the literature review describe the life cycle and blood feeding behaviours ofmosquitoes so that baseline data ofmosquito biology are established. In …

Silene otites (Caryophyllaceae): Attraction of nectar-seeking mosquitoes to inflorescence odours, and temporal variation of flower scent and flower visitors
… odours of S. otites of six populations and Culex pipiens molestus, no differences in attractivity of different populations were observed. Therefore, different scent spectra seem to have the same attractiveness for mosquitoes. In electroantennographic studies with the 13 most common and …

Optimization of Cytogenetic and Physical mapping of Culicinae genomes
… of highly repetitive nature of the Aedes and Culex genomes, the structure of their polytene chromosomes is damaged by ectopic contacts that make the analysis difficult. Mitotic chromosomes from imaginal discs of 4th instar larvae of Aedes aegypti were tested as a source for the physical genome …

Chromosome and Genome Evolution in Culicinae Mosquitoes
… the Culicidae family of mosquitoes. Two genera, Culex and Aedes, from this subfamily have world-wide distribution and are responsible for transmitting of several deadly diseases including Zika, West Nile fevers, chikungunya, dengue, and Rift Valley fevers. Developing high-quality genome assembly …

Non-LTR Retrotransposons in Mosquitoes: Diversity, Evolution, and Analysis of Potentially Active Elements
… clade originally discovered in the mosquito Culex pipiens quinquefasciatus (Mouches et al. 1991), has been implicated in horizontal transfer in three non-sibling species of the Aedes genus (Mouches, Bensaadi, and Salvado 1992). PCR was used to obtain sequences from 18 mosquito species of six …

The Behaviour and Ecology of Mosquito Vectors
… also documented. The second species studied, was Culex pipiens Linnaeus, which is known to be a competent vector of West Nile virus (WNV). Cx. pipiens is considered ornithophilic (bird-feeding) but is believed to switch to mammal blood-meals in the late-summer to early-fall in northern regions. I …
