Toxicity of Amorphigenin from the Seeds of Amorpha fruticosa against the Larvae of Culex pipiens pallens (Diptera: Culicidae)

open access: yesMolecules, 2015
The larvicidal activity of the crude petroleum ether, ethyl acetate, acetone, chloroform and ethanol extracts of Amorpha fruticosa seeds was individually assayed for toxicity against the early fourth-instar larva of the mosquito, Culex pipiens pallens ...

MiR-278-3p regulates pyrethroid resistance in Culex pipiens pallens. [PDF]

open access: yesParasitol Res, 2015
MicroRNAs (miRNAs) regulate gene expression and biological processes including embryonic development, innate immunity, and infection in many species. Emerging evidence indicates that miRNAs are involved in drug resistance. However, little is known about the relationship between the miRNAs and insecticide resistance in mosquitos.

NYD-OP7/PLC regulatory signaling pathway regulates deltamethrin resistance in Culex pipiens pallens (Diptera: Culicidae) [PDF]

open access: yesParasites & Vectors, 2018
Background Investigation of insecticide resistance mechanisms is considered a vital first step towards the creation of effective strategies to control resistant mosquitoes and manage mosquito-borne diseases.

Behavioural response of female Culex pipiens pallens to common host plant volatiles and synthetic blends [PDF]

open access: yesParasites & Vectors, 2015
Background Most mosquito species need to obtain sugar from host plants. Little is known about the chemical cues that Culex pipiens pallens use during their orientation to nectar host plants.

Pyrethroid-resistance is modulated by miR-92a by targeting CpCPR4 in Culex pipiens pallens. [PDF]

open access: yesComp Biochem Physiol B Biochem Mol Biol, 2017
The wide use of pyrethroids has resulted in the emergence and spread of resistance in mosquito populations, which represent a major obstacle in the struggle against vector-borne diseases. Resistance to pyrethroids is a complex genetic phenomenon attributed by polygenetic inheritance. We previously have sequenced and analyzed the miRNA profiles of Culex

Molecular and physiological characterization of the chitin synthase B gene isolated from Culex pipiens pallens (Diptera: Culicidae) [PDF]

open access: yesParasites & Vectors, 2019
Background The growth and development of insects is strictly dependent on the precise regulation of chitin synthase (CHS), which is absent in vertebrates and plants. Therefore, CHS represents an attractive target for insecticides.

Synthesis and Larvicidal Activity of Phrymarolin Derivatives against [PDF]

open access: yesNatural Product Communications, 2016
Twenty-eight new phrymarolin derivatives, including twenty-one ethers, six esters and a dehydroxy phrymarolin, were prepared from phrymarolin I and the structures of all the derivatives were confirmed by 1 H NMR and 13 C NMR spectroscopic and MS data ...

Transcriptional regulation of Culex pipiens mosquitoes by Wolbachia influences cytoplasmic incompatibility [PDF]

open access: yes, 2013
Cytoplasmic incompatibility (CI) induced by the endosymbiont Wolbachia pipientis causes complex patterns of crossing sterility between populations of the Culex pipiens group of mosquitoes. The molecular basis of the phenotype is yet to be defined.

First molecular detection of Plasmodium relictum in Anopheles sinensis and Armigeres subalbatus [PDF]

open access: yesOpen Veterinary Journal, 2020
Background: Plasmodium relictum is one of the most important avian malaria species which is mainly seen in wild birds, with infections reported in more than 70 different species and at high prevalence.

Characterization of East London Culex pipiens s.l. in relation to the risk of transmission to humans of the West Nile virus in Great Britain. [PDF]

open access: yes, 2009
PhDConcerns that West Nile Virus (WNV) may arrive in the UK, prompted investigations of Cx. pipiens s.l., as this species complex has been most often implicated in European urban WNV human outbreaks and the rapid spread of the virus across North ...
