Biological control of Culex mosquitoes using multiple predators
… magnitude and form in cyclopoid copepods. Whilst Culex mosquitoes avoided copepods when selecting oviposition sites, the application of domestic pond dye created an attractant, where oviposition in predator-treated water was favoured. <br/><br/>As predation by copepods was unaffected by dyed …

Causes and consequences of microbiome formation in Culex mosquitoes
… and Phosphorus) shapes the microbiome of larval Culex mosquitoes, as well as how these different environments influence survival to, time to, and size at adulthood. I conducted two types of experiments, both in which I manipulated the resource base and competition. In Chapter 1, I compared …

Detection And Characterization of Insecticide Resistance Mechanisms in Culex Tarsalis
… and West Nile virus. Anopheles gambiae and Culex quinquefasciatus are just two examples of mosquito vectors that possess genetic mutations (denoted kdr and ace-1 ) and/or enhanced detoxifying enzymes (oxidases, esterases, and glutathione-s-transferases) that confer insecticide resistance. …

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. …

Ecology and Management of Riceland Mosquitoes in Africa With Special Reference to Culex Quinquefasciatus
… species, dominated by Anopheles arabiensis, Culex quinquefasciatus, and Anopheles pharoensis, were collected. Species diversity and evenness indices were significantly higher in non-irrigated than irrigated agro-ecosystems. Conversely, mosquito densities were highest in planned rice …

Oviposition Preferences for Infusion-Baited Traps and Seasonal Abundance of Culex Mosquitoes in Southwestern Virginia
… the bionomics and ovipositional preferences of Culex restuans Theobald and Culex pipiens Linnaeus using ovitraps and gravid traps. Both species have been implicated as enzootic and epizootic vectors of West Nile virus (WNV) and these studies provide information on the relative abundance of …

A cytogenetic map for the genomic studies of the West Nile Virus vector Culex tarsalis
Culex tarsalis is a major vector of West Nile Virus (WNV) in North America. Although the genome for this species was recently sequenced, the physical genome map has not developed. Unlike other Culex species, that have sex-determination locus on chromosome 1, the sex locus in Cx. tarsalis is located …

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 …
