Mosquitoes 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. Gravid Culex 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 differ from water...

An entomological study was conducted in a Leishmania infantum focus, including the identification of the sand fly species, the detection and the characterization of Leishmania DNA in female sand flies, and blood meal origins in engorged sand flies. A total of 643 sand flies (31% female, 69% male) was identified based on their morphological features or molecular markers. Ten different species were identified, with Phlebotomus perniciosus, the confirmed vector of L. infantum, being the most abundant (56%), P...

Bromeliads serve as a key environmental resource for Aedes 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 reducing Ae. albopictus egg abundance in bromeliad plants...

Visceral leishmaniasis (VL), transmitted by the sand fly, Phlebotomus argentipes, is frequently reported on the Indian subcontinent where its basic ecology is largely unknown. Our objective was to evaluate the effectiveness of sugar solution (10%), containing colored food dye (0.5%) applied to peridomestic vegetation, to mark P. argentipes and subsequently estimate horizontal movement by capturing dye-marked specimens in CDC light traps in a village in Bihar, India. From September 30 to November 27, 2016, a total of 667 captured sand flies were successfully marked using sugar baits, of which 608 were P...

Successful colonies of the biting midge Forcipomyia taiwana (Shiraki) were established and maintained in the laboratory by feeding blood with an artificial blood-feeding apparatus, rearing larvae on a soil substrate employing algae liquid, and setting suitable mating cages. The feeding rates of F. taiwana fed on pig blood (69.9%) and artificial blood (72.7%) were not significantly different from those fed on human blood (67.0%). The mean numbers of adults produced by females fed on the artificial blood and the human blood were 32...

To explain the patchy distribution of West Nile virus (WNV), we propose that avian immunity encountered by Culex 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 engorged Culex pipiens, was 23-fold greater at test sites compared to control sites, and the density of blood-engorged Cx...

There have been several important outbreaks of mosquito-borne diseases in the Neotropics in recent years, particularly in Brazil. Some taxa are also considered to be indicators of environmental health. Despite the importance of understanding insect abundance and distribution to the understanding of disease dynamics and design strategies to manage them, very little is known about their ecology in many tropical regions. We studied the abundance and diversity of mosquitoes and sand flies in the Bahia State of Brazil, a point of origin for arbovirus outbreaks, including Zika and Chikungunya fever...

Malaria 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...

The horse flies of El Tarf Province, northeastern Algeria comprise 15 species within two subfamilies (Chrysopsinae and Tabaninae) belonging to five genera (Atylotus, Chrysops, Dasyrhamphis, Haematopota, and Tabanus). The genera Chrysops, Dasyrhamphis, and Haematopota are represented by two species for each, while the genera Atylotus and Tabanus are represented by four and five species, respectively. Seasonal abundance was assessed from mid-March until the end of September, 2017 for the trapped species. Haematopota pluvialis and Tabanus autumnalis appeared in April and lasted until September with a peak in May...

Lucilia 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...

Karyotypes of Aedes (Culicidae) mosquitoes (Ae. excrucians, Ae. behningi, and Ae. 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 chromosomes in the imaginal discs of Ae. excrucians, Ae. behningi, and Ae...

We evaluated the pathogenicity of the entomopathogenic nematodes native to Mexico, Heterorhabditis indica, Heterorhabditis sp. and Steinernema sp., towards M. domestica under controlled conditions. For adults, concentrations of 1,600 (A) and 1,200 (B) nematodes/ml were considered. For larvae, only the first concentration applied to filter paper, wheat bran, and peat moss as substrates was evaluated. An analysis of variance showed that the differences in adult mortality were only significant (p = 0.0001) among nematode species but not among concentrations within species...

Cutaneous leishmaniasis caused by Leishmania tropica, transmitted by Phlebotomus sergenti and Phlebotomus arabicus, has been detected in Israel. This research strives to identify the complexity of temperature effects on vectors of L. tropica and to analyze seasonality and distribution across altitudinal levels. Sand fly trappings were conducted monthly during 2015-2016 in an endemic region for L. tropica in the eastern Galilee. Trappings were conducted in hyrax den sites across a broad topographic and climatic gradient...

Amblyomma 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 of A. 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...

We focused on the analysis of biological parameters of two different abundant populations of Dipetalogaster maximus (Uhler) (Hemiptera: Reduviidae: Triatominae) from northwestern Mexico. The biological parameters were related to hatching of eggs, life cycle, and meal needed for molting by each instar of two populations from environmentally similar areas (El Fandango and San Dionisio) with a similar number of available hosts as blood meal sources. The D. maximus populations from the two locations were evaluated and compared...

Host identity, habitat type, season, and interspecific interactions were investigated as determinants of the community structure of fleas on wild carnivores in northwestern Mexico. A total of 540 fleas belonging to seven species was collected from 64 wild carnivores belonging to eight species. We found that the abundances of some flea species are explained by season and host identity. Pulex irritans and Echidnophaga gallinacea abundances were significantly higher in spring than in fall season. Flea communities on carnivore hosts revealed three clusters with a high degree of similarity within each group that was explained by the flea dominance of E...
