Aedes aegypti is an important subtropical vector species and is predicted to have a limited year-round distribution in the southern United States. Collection of the species has not been officially verified in Oklahoma since 1940. Adult mosquitoes were collected in 42 sites across 7 different cities in Oklahoma using 3 different mosquito traps between May and September 2016. Between July and September 2016, 88 Ae. aegypti adults were collected at 18 different sites in 4 different cities across southern Oklahoma...

The comparative efficacy of ultra-low volume applications of deltamethrin, permethrin, and malathion against specific adult populations of Culex quinquefasciatus , a primary regional vector of Saint Louis encephalitis and West Nile virus, using field cage tests is described. At labeled application rates, the estimated mass median diameters for Fyfanon(®), Evoluer™, and DeltaGard(®) were 18.32, 19.24, and 17.44 μm, respectively. No significant differences (P ≥ 0.01) in mean percent control were observed across all 3 wild populations and a susceptible Sebring strain tested with Fyfanon, DeltaGard, and Evoluer, providing 98...

The present study investigates the effect of multiple immersions on Psorophora albigenu eggs and their development cycle under laboratory conditions. Engorged Ps. albigenu specimens were captured in January 2011 around the Transpantaneira Park Road, Mato Grosso, Brazil, using CO2-baited Centers for Disease Control and Prevention light traps. Psorophora albigenu eggs (n = 1274) were subjected to immersion, with a hatching rate between 49% and 73%. The Williams average showed a peak of 29% hatched eggs in the 3rd immersion; after 4-5 immersions, the effect of additional immersions was generally negligible...

Multiple surveillance traps are currently available for adult mosquito surveillance. In this study, 2 new types, the Maxttrac™ Uno and Maxttrac™ Breeze mosquito traps, were compared against the BioGents™-Sentinel trap (BGS) for overall success in collecting Aedes albopictus in a 1,027-m(2) vehicle enclosure and in the field. The enclosure test results showed both traps collected significantly fewer Ae. albopictus, compared to the BGS trap. The modification of using all BG lures for each trap did not increase the number of mosquitoes collected in the 2 new traps, when compared to collection with the original lures tested in the vehicle enclosure...

The effect of fluctuating ambient air and water temperatures and relative humidity (RH) on the population parameters of Culex pipiens was studied using life table data during the winter-spring and summer-autumn seasons in Giza Province, Egypt. In winter-spring (20.46 ± 1.8°C and 51.68 ± 3.63% RH), the preadult survival rate for Cx. pipiens was 80.65%, which was higher than the 50.00% observed in the summer-autumn (30.19 ± 0.67°C and 52.68 ± 8.04% RH). During the winter-spring period, the developmental time of egg, larvae, and pupae of Cx...

During the 2014 chikungunya (CHIK) outbreak in the Caribbean, we performed entomological surveys on 3 United States Virgin Islands (USVI): St. Croix, St. Thomas, and St. John. We aimed to evaluate the potential for chikungunya virus (CHIKV) transmission in the USVI. The surveys took place between June 19, 2014, and June 29, 2014, during the dry season in USVI. A total of 1,929 adult mosquitoes belonging to 4 species- Culex quinquefasciatus (68.4%), Aedes aegypti (29.7%), Ae. mediovittatus (1.3%), and Ae. sollicitans (<1%)-were detected...

Temperature and rainfall are important drivers of mosquito abundance and have been used in previous studies as the basis for predictive models. To elucidate patterns of mosquito population dynamics in urban environments, the variation in mosquito abundance over a year and its association with climatic variables were analyzed. The Akaike information criterion was used to analyze the correlations between abundance and climate variables in mosquito populations collected in 2 urban parks: Alfredo Volpi Park and Burle Marx Park...

The droplet spectrum of a mosquito adulticide spray plume determines its ability to drift through the target area, impinge on the mosquito, deliver a toxic dose, and the risk of environmental contamination. This paper provides data on droplet spectra produced from 6 nozzles in a high-pressure nozzle spray system and 5 rotary nozzle systems for common mosquito adulticides. Spray plume spectra were measured by laser diffraction. High-pressure nozzles were evaluated at pressures ranging from 500 psi to 6,000 psi...

We report new records for Culiseta annulata from Kuwait. Prior to our records, Culiseta longiareolata was the only Culiseta sp. known from Kuwait. Culiseta annulata is a vector of Tahyna virus (Bunyaviridae) to humans throughout Asia. We tested a limited number of mosquitoes for Tahyna virus and other viruses. Tahyna virus was not detected, but we did discover a mosquito Densovirus in a pool of Cs. annulata using next generation sequencing.

Emerging technology designed to kill mosquito larvae with sound waves may present a nonchemical and nonbiological alternative to reduce larval populations of key medically important mosquito species such as Aedes aegypti in containers or catchments of water. These devices could benefit integrated vector management programs facing public resistance to the use of chemical or biological larvicides in stored drinking water. In this study we investigate the efficacy of a Larvasonic SD-Mini Acoustic Larvicide device in reducing larval populations of Ae...

Mosquito-borne diseases have been increasing at an alarming rate over the past decades. In Malaysia, one finds several important mosquito-borne diseases such as Japanese encephalitis, dengue, malaria, and chikungunya. Mosquito surveillance and control programs are the most effective way of detecting and controlling mosquito-borne diseases, but these programs are less effective without an aware and well-informed general public. In 2014 we used a questionnaire to evaluate the extent of awareness of basic mosquito biology and mosquito-borne diseases in 6 villages, Kampung Masjid, Kampung Teluk Gedung, Kampung Teluk Dalam, Kampung Ujung Kelawai, Kampung Sungai Pinang Besar, and Kampung Sungai Pinang Kechil on Pangkor Island, Malaysia...

An updated checklist of 50 species of mosquitoes found in Montana is presented and includes 2 new records (Aedes niphadopsis and Anopheles walkeri) that can be added to the 2005 state list by Darsie and Ward. The results of a statewide mosquito surveillance program, conducted annually from 2004 to 2015, facilitated the establishment of an abundance rating of the species in the state and expanded the known geographic range for Coquillettidia perturbans, Ae. nigromaculis, and Culiseta minnesotae.

Research on natural insecticides has intensified with the spread of resistance to chemicals among insects, particularly disease vectors. To evaluate compounds, the World Health Organization (WHO) has published standardized procedures. However, those may be excessively compound-consuming when it comes to assessing the activity of natural extracts and pure compounds isolated in limited amount. As part of our work on the discovery of new mosquito larvicides from Amazonian plants, we developed a compound-saving assay in 5-ml glass tubes instead of WHO larval 100-ml cups...

Although insecticide spray droplets will potentially impinge on many exoskeletal body regions, traditional mosquito topical bioassays focus insecticide application to the mesothoracic pleural or dorsal area. Concentrations of permethrin and malathion found in droplets from ultra-low volume and low-volume sprays were evaluated for efficacy against adult Culex quinquefasciatus using a topical application bioassay. Results document nonuniform insecticide sensitivity across body regions, which has not been previously assessed in mosquitoes...
