Colonization of Coquillettidia linealis (Skuse) with reference to other Coquillettidia and Mansonia species
ABSTRACTThe immature stages ofCoquillettidia andMansonia mosquitoes are cryptic and spend the duration of their development attached to the tissues of subsurface aquatic plants. This obligatory association makes them difficult to collect and has precluded detailed investigation of the biology ofCoquillettidia linealis, a species of significant pest and vector status in Australia, as well as other species in the genusCoquillettidia in Australia and elsewhere. This paper describes the first successful establishment and maintenance of a colony ofCq. linealis. Blood ‐seeking wild adults were collected and induced to oviposit...

Modeled distributions of Aedes japonicus japonicus and Aedes togoi (Diptera: Culicidae) in the United States, Canada, and northern Latin America
ABSTRACTThe Asian bush mosquito,Aedes japonicus japonicus, and the coastal rock pool mosquito,Aedes togoi, are potential disease vectors present in both East Asia and North America. While their ranges are fairly well ‐documented in Asia, this is not the case for North America. We used maximum entropy modeling to estimate the potential distributions ofAe. togoi andAe. j. japonicus in the United States, Canada, and northern Latin America under contemporary and future climatic conditions. Our results suggest suitable habitat that is not known to be occupied forAe. j. japonicus in Atlantic and western Canada, Alaska, the wes...

Effect of acute and chronic exposure to ammonia on different larval instars of Anopheles darlingi (Diptera: Culicidae)
ABSTRACTAnopheles darlingi (Diptera: Culicidae) is the most important vector of malaria in South America and has already been found in peri ‐urban areas that commonly contain toxic nitrogenous compounds, such as ammonia. The adaptation of mosquitoes to polluted breeding sites can increase their distribution and affect the dynamics of vector‐borne diseases such as malaria. Therefore, the present study investigated the tolerance of la rval instars ofAn. darlingi to ammonia under acute and chronic exposure conditions.Anopheles darlingi larval mortality, development time, and pupal and adult production using larvae of the ...

Spatial repellency and other effects of transfluthrin and linalool on Aedes aegypti and Aedes albopictus
ABSTRACTIn the present study, the effects of two spatial repellents (SR) were determined forAedes aegypti andAe albopictus, the main vectors of dengue, Chikungunya, and Zika fever. The modular high ‐throughput screening system (HITSS) was used to evaluate the response of both species to transfluthrin and linalool SR at different concentrations. The highest spatial repellency results forAe. aegypti were obtained by transfluthrin to 0.001% with 37.50 ± 4.33%, and for linalool to 10% with 77.50 ± 3.90%. ForAe. albopictus, the highest spatial repellency percentages for transfluthrin 0.01% were 45.00 ± 3.78%, and linalool ...

Evidence of Culiseta mosquitoes as vectors for Plasmodium parasites in Alaska
ABSTRACTMosquito vectors play a crucial role in the distribution of avianPlasmodium parasites worldwide. At northern latitudes, where climate warming is most pronounced, there are questions about possible changes in the abundance and distribution ofPlasmodium parasites, their vectors, and their impacts to avian hosts. To better understand the transmission ofPlasmodium among local birds and to gather baseline data on potential vectors, we sampled a total of 3,909 mosquitoes from three locations in south ‐central Alaska during the summer of 2016. We screened mosquitoes for the presence ofPlasmodium parasites using molecula...

Arbovirus surveillance using FTATM cards in modified CO2 ‐baited encephalitis virus surveillance traps in the Northern Territory, Australia
ABSTRACTIn 2016, modified CO2‐baited encephalitis virus surveillance (EVS) traps were evaluated for flavivirus surveillance in the Northern Territory, Australia. The traps were fitted with honey‐soaked nucleic acid preservation cards (FTATM) for mosquitoes to expectorate virus while feeding on the cards. Cards were tested for the presence of selected arboviruses, with two cards testing positive for Kunjin virus and Alfuy, while sentinel chickens tested in parallel also showed Kunjin virus activity at the same time. The results from the cards and vector mosquito feeding rates indicate that CO2‐baited EVS traps coupled...

Estimated resistance of the malaria mosquito Anopheles messeae s.l. to the insecticide malathion
ABSTRACTResistance to agricultural pesticides is an important and insufficiently studied concern for pest and disease vector research. We determined the malathion resistance of species in theAnopheles maculipennis mosquito group in a habitat near Novosibirsk, Russia. Most of the 851 individuals we measured were members of theAnopheles messeae s.l. complex (An. messeae andAn. daciae species). The LC50 value for malathion was 0.052 mg/L for the mixed specimens, and we failed to find any differences between species. The LC50 value was within the range of values for malathion resistance ofAnopheles stephensi andCulex quinquefa...

Plague management of prairie dog colonies: degree and duration of deltamethrin flea control
ABSTRACTPlague is a flea ‐borne disease of mammalian hosts. On the grasslands of western North America, plague stifles populations ofCynomys spp. prairie dogs (PDs). To manage plague, PD burrows are treated with 0.05% deltamethrin dust that can suppress flea numbers and plague transmission. Here, we evaluate the degree and duration of deltamethrin flea control with three PD species at six sites across four U.S. states. Data were simultaneously collected at paired plots. Burrows from one randomly assigned member of each pair were treated with deltamethrin; non ‐treated plots served as experimental baselines. Flea contro...
