Ecological modeling over seven years to describe the number of host ‐seeking Amblyomma americanum in each life stage in northeast Missouri
ABSTRACTAmblyomma americanum (L.), the lone star tick, is a vector of pathogens in humans and other animals throughout the United States. Our objective was to characterize how environmental factors influence patterns ofA. americanum activity throughout its life cycle by creating statistical models that describe the number of active off ‐host larvae, nymphs, and adults in northeast Missouri from 2007 to 2013. Ticks were collected every other week from a permanent sampling grid in a second‐growth forest and in an old field habitat. Each of the three life stage models considered six meteorological variables and one biotic...

Potential of essential oils to prevent fly strike and their effects on the longevity of adult Lucilia sericata
ABSTRACTLucilia sericata is a facultative ectoparasite causing fly strike or myiasis in warm ‐blooded vertebrates. It is controlled by traps or insecticides, but both have drawbacks and alternative ways of control are urgently needed. Essential oils (EOs) of vetiver (Chrysopogon zizanioides), cinnamon (Cinnamomum zeylanicum), and lavender (Lavandula angustifolia) and their blends (OBs); OB1 (2 ml of each EO plus 4 ml of sunflower oil as a carrier) and OB2 (2 ml of each EO) were tested. Oils were tested at 5% for deterrence assays, and a dose response assay 0.01 ‐0.6%, was conducted to determine forced‐contact toxicit...

Behavioral responses of gravid Culex quinquefasciatus, Aedes aegypti, and Anopheles quadrimaculatus mosquitoes to aquatic macrophyte volatiles
ABSTRACTMosquitoes use many cues to assess whether a habitat is conducive for reproduction, possibly including the presence of stimuli from aquatic macrophytes. The effect of water infusions of water hyacinth (Eichhornia crassipes), water lettuce (Pista stratioles), parrotfeather(Myriophyllum aquaticum), and water pennywort (Hydrocotyle umbellata) on mosquito oviposition and attraction was investigated. GravidCulex quinquefasciatus deposited significantly more egg rafts in water hyacinth, water lettuce, or Bermuda hay (positive control) infusions compared to water, while water pennywort and parrotfeather infusions did not ...

A comparative analysis of the metaphase karyotypes of Aedes excrucians, Ae. behningi, and Ae. euedes (Diptera: Culicidae) imaginal dis сs
ABSTRACTKaryotypes ofAedes (Culicidae) mosquitoes (Ae. excrucians, Ae. behningi, andAe. euedes) have been analyzed using the metaphase chromosomes of imaginal discs. Lacto ‐aceto‐orcein, C‐banding, and DAPI staining have detected species‐specific features in the morphology and lengths of these chromosomes in the examined species. Species‐specific features of chromosome 1 in the location of heterochromatin blocks have been shown. Thus, the metaphase chromosom es in the imaginal discs ofAe. excrucians, Ae. behningi, andAe. euedes are a characteristic for species identification of mosquito species.

Diversity of Anopheles mosquitoes from four landscapes in the highest endemic region of malaria transmission in Brazil
ABSTRACTMalaria transmission in South America is overwhelmingly located in the Amazon region with limited cases outside that biome. A key factor in the mitigation of malaria transmission is the determination of vector diversity and bionomics in endemic areas.Anopheles mosquitoes were collected in four different landscapes of Cruzeiro do Sul ‐Acre, the current area with highest malaria transmission in Brazil. We performed adult mosquito collections every three months over two years and associated vector occurrence with local abiotic factors. A total of 1,754Anopheles belonging to nine species were collected, but only four...

Focal amplification and suppression of West Nile virus transmission associated with communal bird roosts in northern Colorado
ABSTRACTTo explain the patchy distribution of West Nile virus (WNV), we propose that avian immunity encountered byCulex vectors regulates WNV transmission, particularly at communal bird roosts. To test this hypothesis, we selected two test sites with communally roosting American robins (Turdus migratorius) and two control sites that lacked communal roosts. The density of vector ‐vertebrate contacts, represented by engorgedCulex pipiens, was 23 ‐fold greater at test sites compared to control sites, and the density of blood‐engorgedCx. pipiens measured in resting mosquito traps correlated positively with the presence o...

Bromeliad targeted foliar treatments with Aqualuer ® 20‐20 for hot spot mitigation using three hand sprayers against Aedes albopictus (Diptera: Culicidae)
ABSTRACTBromeliads serve as a key environmental resource forAedes albopictus (Skuse) in some peridomestic landscapes and are not addressed through conventional source reduction. As an alternative, three handheld sprayers were evaluated in point ‐source applications of permethrin to bromeliads in Saint Augustine, FL. Each machine was screened for its utility in point‐source harborage treatments, while we simultaneously evaluated bromeliad‐focused treatments for reducingAe. albopictus egg abundance in bromeliad plants. Semi ‐field tests against cagedAe. albopictus produced 100% mortality at 24 h with each sprayer. Th...

Temperature effects on the activity of vectors for Leishmania tropica along rocky habitat gradients in the Eastern Mediterranean
ABSTRACTCutaneous leishmaniasis caused byLeishmania tropica, transmitted byPhlebotomus sergenti andPhlebotomus arabicus, has been detected in Israel. This research strives to identify the complexity of temperature effects on vectors ofL. tropica and to analyze seasonality and distribution across altitudinal levels. Sand fly trappings were conducted monthly during 2015 ‐2016 in an endemic region forL. tropica in the eastern Galilee. Trappings were conducted in hyrax den sites across a broad topographic and climatic gradient. Using N ‐mixture models, we investigated the activity levels of sand flies as related to tempora...
