The oviposition pheromone of Culex quinquefasciatus was synthesized in a racemic form in a simple (five steps), efficient, high yielding (45% total yield), and low cost way (use of relatively low cost reagents). Our synthetic racemic pheromone (SRP) was tested in the laboratory for its bioactivity on Culex pipiens biotype molestus, which is a member of the species complex that Culex quinquefasc...

Mosquitoes found hibernating in underground shelters were studied in western Bohemia, Czech Republic. Species collected included Culiseta alaskaensis, Cs. annulata, Cs. glaphyroptera, Culex spp., and Anopheles maculipennis s.l.. Culex spp. were the most common, followed by Cs. glaphyroptera and Cs. annulata with few records of Cs. alaskaensis and An. maculipennis s.l.. Culex spp. were found in ...

This study was carried out to know about the various species of mosquito in Surguja district during June 2021 May 2022. Larvae and adult mosquitoes were also studied currently. In this study, 15 belonging a total 3 genera found which are as follows Aedes, Culex and, Anopheles (64.39%) highly hegemonic followed by (25.07%) Aedes (10.52%) respectively. albopictus, Culex. Quinquefasciatus complete...

Adult mosquitoes (Diptera: Culicidae) were collected in 2007 and tested for specific viruses, including West Nile virus, as part of the ongoing arbovirus surveillance efforts in the state of Iowa. A subset of these mosquitoes (6,061 individuals in 340 pools) was further tested by reverse transcription-polymerase chain reaction (RT-PCR) using flavivirus universal primers. Of the 211 pools of Cul...

Croatian fauna consists of 50 mosquito species, and 15 of them have medical importance. Only 10 species are capable of transmitting the West Nile Virus (WNV). In Croatia the most capable vector is Culex pipiens c. According to species distribution and abundance all of Croatia is a risk area for WNV transmission. Culex pipiens c. is the dominant species (share of 5-10%) in eastern Croatia, but C...

Mosquitoes are important living organisms that participate in the different levels of food chains. However, many families include vector species capable to transmit viruses, bacteria and parasites both humans animals, threatening public health. The goal this work was describe biological diversity mosquito areas M'sila; Algeria based on ecological nature their habitat. breeding sites found were ...

background: during recent years transmission of dirofilaria immitis (dog heart worm) by culex pipiens and west nile virus have been reported from iran. the present study was preformed for evaluating the susceptibility status of cx. pipiens collected from capital city of tehran, iran . methods: four insecticides including: ddt 4%, lambdacyhalothrin 0.05%, deltamethrin 0.05% and cyfluthrin 0.15 %...

Attraction of Culex quinquefasciatus Say, Culex tarsalis Coquillett, Culex nigripalpus Theobald, and Aedes aegypti (L.) to avian and other host odors was investigated in a dual-port olfactometer. Although attraction to a human arm was high for Ae. aegypti (>80%) and low for all Culex spp. (<25%), all species responded similarly to a chicken (55.3-73.6%). Responses of Ae. aegypti, Cx. quinquefas...
