Impacts of environmental conditions on fleas in black ‐tailed prairie dog burrows
ABSTRACTSylvatic plague, caused by the bacteriumYersinia pestis and transmitted by fleas, occurs in prairie dogs of the western United States. Outbreaks can devastate prairie dog communities, often causing nearly 100% mortality. Three competent flea vectors, prairie dog specialistsOropsylla hirsuta andO. tuberculata, and generalistPulex simulans, are found on prairie dogs and in their burrows. Fleas are affected by climate, which varies across the range of black ‐tailed prairie dogs (Cynomys ludovicianus), but these effects may be ameliorated somewhat due to the burrowing habits of prairie dogs. Our goal was to assess ho...

The changing triad of plague in Uganda: invasive black rats (Rattus rattus), indigenous small mammals, and their fleas
ABSTRACTRattus rattus was first reported from the West Nile Region of Uganda in 1961, an event that preceded the appearance of the first documented human plague outbreak in 1970. We investigated how invasiveR. rattus and native small mammal populations, as well as their fleas, have changed in recent decades. Over an 18 ‐month period, a total of 2,959 small mammals were captured, sampled, and examined for fleas, resulting in the identification of 20 small mammal taxa that were hosts to 5,109 fleas (nine species). Over three‐fourths (75.8%) of captured mammals belonged to four taxa:R. rattus, which predominated inside hu...

Behavioral characteristics and endosymbionts of two potential tularemia and Rocky Mountain spotted fever tick vectors
ABSTRACTDue to climate change ‐induced alterations of temperature and humidity, the distribution of pathogen‐carrying organisms such as ticks may shift. Tick survival is often limited by environmental factors such as dryness, but a predicted hotter and wetter world may allow the expansion of tick ranges.Dermacentor andersoni andD. variabilis ticks are morphologically similar, co ‐occur throughout the Inland Northwest of Washington State, U.S.A., and both can be injected with pathogenicRickettsia andFrancisella bacteria. Differences in behavior and the potential role of endosymbioticRickettsia andFrancisella in these ...

Distribution and preference for oviposition sites of Aedes albopictus (Skuse) in the metropolitan area of Bel ém, in the Brazilian Amazon
ABSTRACTThe mosquitoAedes albopictus is a vector of several arboviruses transmitted to humans. They have a sylvatic behavior, occurring in rural areas. However, reports of their adaptation to anthropic environments have been increasing. The aim of this study is to investigate the presence and distribution ofAe. albopictus in the Metropolitan Region of Bel ém in the Brazilian Amazon and evaluate its preference for either natural or artificial breeding sites under the weather conditions of the Amazon. Ovitraps (artificial breeding sites) and bamboo internodes (natural breeding sites) were deployed in neighborhood peridomici...

Identification of mucins and their expression in the vector mosquito Aedes albopictus
ABSTRACTMucins, the main structural components of vertebrate respiratory, digestive and reproductive tract mucus, as well as insect peritrophic matrix, play important roles in protecting host cells from invading microbes and difficult external environments. Mucins are characterized by highly glycosylated proteins constituting the mucin domain that is rich in repetitive sequences of threonine, serine, and proline (PTS). Despite potential important roles, mosquito mucins remain largely uncharacterized. Here, we performed bioinformatics analyses to identify proteins with PTS repeat domain and predicted 43 mucins or mucin ‐r...

Assemblage variation of mosquitoes (Diptera: Culicidae) in different land use and activity periods within a lowland tropical forest matrix in Campeche, Mexico
ABSTRACTMost mosquito species are active during a certain part of the day, but climatic factors such as light intensity and relative humidity play an important role in the control of their activity. We selected three types of land use that were sampled in state of Campeche in 2018 (low semi ‐evergreen forest, secondary low semi‐evergreen forest, and mango plantation), using ten CDC light traps baited with CO2, that were active during nine hours of three activity periods (dawn, noon, and nightfall). A GLM was used to investigate changes in the assembly of mosquitoes between different types of land use and temporal varia...

Efficiency of CO2 ‐baited CDC miniature light traps under semi‐field conditions and characterizing response behaviors of female Aedes aegypti (Diptera: Culicidae)
ABSTRACTAedes aegypti (L.) (Diptera: Culicidae) is an important vector of viruses causing dengue, Zika, chikungunya, and yellow fever and as such is a threat to public health worldwide. Effective trapping methods are essential for surveillance of both mosquito species and disease presence. The Centers for Disease Control Miniature Light Trap (CDC ‐MLT) is an updated version of the New Jersey light trap, which was developed early in the 20th century. This trap is widely reported as being less successful forAe. aegypti than for other mosquito species, although the reason for this is unclear. This trap has engendered moreAe...

Exploiting the chemical ecology of mosquito oviposition behavior in mosquito surveillance and control: a review
ABSTRACTVector control is an important component of the interventions aimed at mosquito ‐borne disease control. Current and future mosquito control strategies are likely to rely largely on the understanding of the behavior of the vector, by exploiting mosquito biology and behavior, while using cost‐effective, carefully timed larvicidal and high‐impact, low‐volume adulticidal ap plications. Here we review the knowledge on the ecology of mosquito oviposition behavior with emphasis on the potential role of infochemicals in surveillance and control of mosquito‐borne diseases. A search of PubMed, Embase, Web of Scienc...

Molecular relationships of introduced Aedes japonicus (Diptera: Culicidae) populations in British Columbia, Canada using mitochondrial DNA
ABSTRACTAedes japonicus japonicus (Theobald) is a relatively recent immigrant to the Pacific Northwest, having been collected in Washington State in 2001 and in British Columbia (BC) since 2014. We applied a molecular barcoding approach to determine the phylogenetic relationship ofAe. j. japonicus populations in BC with those from around the world. We sequenced a 617 base ‐pair segment of the cytochrome c oxidase 1 gene and a 330 base‐pair region of the NADH dehydrogenase 4 gene to find genetic variation and characterize phylogenetic and haplotypic relationships based on nucleotide divergences. Our results revealed low...

Response of small mammal and tick communities to a catastrophic wildfire and implications for tick ‐borne pathogens
ABSTRACTThrough their potentially devastating impacts on the environment, wildfires may impact pathogen, vector, and host interactions, leading to changing risks of vector ‐borne disease in humans and other animals. Despite established risks for tick‐borne disease and increasing frequency and severity of wildfires in the United States, impacts of wildfire on ticks and tick‐borne pathogens are understudied. In 2015, the large Wragg fire extensively burned a long‐ term field site at Stebbins Cold Canyon University of California Reserve (CC). We characterized the tick, reservoir host and pathogen community over a two...

Comparison of blue cotton and blue polyester fabrics to attract hematophagous flies in cattle farms in Thailand
ABSTRACTTabanids and stable flies are important nuisances to livestock and sometimes humans. Nzi, Vavoua, and Biconical traps or insecticide ‐impregnated blue screens are commonly used to attract and catch these flies. Such devices are made of a specific cotton or cotton‐polyester phthalogen blue fabric acting as a visual attractant. However, the cost of cotton fabrics is high, and they are no longer available due to toxic dyes. The present study compared four blue polyester fabrics produced in Thailand with a reference blue cotton‐polyester fabric made in France by TDV® to attract hematophagous flies. Vavoua traps ...

Bartonella species and haplotypes in rodents and their fleas in Lanzarote and El Hierro in the Canary Islands, Spain
ABSTRACTBecause isolated ecosystems contribute to species variability, especially oceanic island ecosystems, the present work focused on the study of theBartonella species and haplotypes in Lanzarote and El Hierro, two Canary islands with evident bioclimatic differences between them. A total of 123 rodents and 110 fleas from two islands were screened for the presence ofBartonella by PCR analysis of thegltA andnuoG genes. The overall prevalence was 5.7% in rodents and 20.4% in fleas. A total of sevengltA ‐haplotypes was found in both rodents and fleas, belonging to the speciesBartonella mastomydis andBartonella tribocorum...
