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

Parasites & 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.

New native Bacillus thuringiensis strains induce high insecticidal action against Culex pipiens pallens larvae and adults. [PDF]

BMC Microbiol, 2023
Mosquitoes of many species are key disease vectors, killing millions of people each year. Bacillus thuringiensis -based insecticide formulations are largely recognized as among the most effective, ecologically safe, and long-lasting methods of managing ...

MicroRNA-989 targets 5-hydroxytryptamine receptor1 to regulate ovarian development and eggs production in Culex pipiens pallens. [PDF]

Parasit Vectors, 2023
Background Female mosquitoes need a blood meal after mating for their eggs to develop, and this behavior leads to the spread of pathogens. Therefore, understanding the molecular regulation of reproduction in female mosquitoes is essential to control ...

Toxic Effects of Perilla frutescens (L.) Britt. Essential Oil and Its Main Component on Culex pipiens pallens (Diptera: Culicidae). [PDF]

Plants (Basel), 2023
Sustainable control of mosquitoes, vectors of many pathogens and parasites, is a critical challenge. Chemical insecticides are gradually losing their effectiveness because of development of resistance, and plant metabolites are increasingly being ...

Detection and persistence of environmental DNA (eDNA) of the different developmental stages of a vector mosquito, Culex pipiens pallens. [PDF]

PLoS One, 2022
Preventing mosquito-borne infectious diseases requires that vector mosquitoes are monitored and controlled. Targeting immature mosquitoes (eggs, larvae, and pupae), which have less mobility than adults, is an effective management approach.

Spatial distribution and environmental correlations of Culex pipiens pallens (Diptera: Culicidae) in Haidian district, Beijing. [PDF]

J Med Entomol
Culex pipiens pallens Coquillett, 1898 (Diptera: Culicidae) was the dominant health threat to mosquito species in Beijing, and it is important to unravel the spatial distribution and environmental correlations of Cx. pipiens pallens in Beijing.

Sporogony and sporozoite rates of avian malaria parasites in wild Culex pipiens pallens and C. inatomii in Japan [PDF]

Parasites & Vectors, 2015
Background Malaria infection in mosquitoes is traditionally detected by microscopic examination for Plasmodium oocysts and sporozoites. Although PCR is now widely used, the presence of parasite DNA in a mosquito does not prove that sporogony is achieved.

Physiological characterization of chitin synthase A responsible for the biosynthesis of cuticle chitin in Culex pipiens pallens (Diptera: Culicidae). [PDF]

Parasit Vectors, 2021
The pathogens transmitted by mosquitoes to humans and animals cause several emerging and resurgent infectious diseases. Increasing insecticide resistance requires rational action to control the target vector population. Chitin is indispensable for insect

Lethal and sublethal effects of spinosad on dengue vector mosquito, Aedes albopictus and bancroftian filariasis vector mosquito, Culex pipiens pallens

Journal of Vector Borne Diseases
Background & objectives: Aedes albopictus and Culex pipiens pallens are important vectors of many viruses and have had resistance to chemical pesticides. Spinosad is a selective biological insecticide to control urban mosquitoes.
