The prevalence, abundance, and molecular characterization of Lipoptena deer keds from cervids
The objectives of this study were to investigate the prevalence and abundance of deer keds on various cervids in Lithuania, to molecularly characterize the deer ked species based on mitochondrialCOI and16S rRNA genes, and to compare them withLipoptena species found in other countries. A total of 11,939 deer keds (Lipoptena cervi andLipoptena fortisetosa) was collected from the fur of 30 cervids in Lithuania between 2015 and 2019. The values of infestation with deer keds differed among the species of the hosts. Moose and red deer were more frequently infested withL. cervi than withL. fortisetosa, whileL. fortisetosa was fou...

Insecticide resistance and molecular characterization of knockdown resistance (kdr) in Culex quinquefasciatus mosquitoes in Sri Lanka
ABSTRACTResistance to pyrethroids (PY) and organophosphate (OP) insecticides is widespread among populations ofCulex quinquefasciatus, the major vector of lymphatic filariasis (LF). The present study was designed to detect the L1014Fkdr (knockdown resistant) mutation amongCx. quinquefasciatus populations in the filarial belt of Sri Lanka. Mosquitoes were reared from field ‐caught larvae from seven localities where LF is endemic. Susceptibility status ofCx. quinquefasciatus to adulticides, 0.05% deltamethrin, 0.75% permethrin, 5% malathion, and the larvicide temephos was determined using the standard WHO susceptibility te...

Diapause influenced oviposition behavior and physical egg hatch cues of Aedes atropalpus (Diptera: Culicidae): traits that may influence successful colonization of riverine rock pools
ABSTRACTMosquitoes have developed specialized oviposition strategies that allow them to develop in a wide variety of aquatic habitats. Environmentally cued hatching traits may also play an important role in the successful colonization of some larval habitats, but this subject has remained largely unexplored in Culicidae.Aedes atropalpus (Coquillett) is an autogenous rock pool specialist that may maintain unique adaptations for oviposition and egg hatching. We investigated the egg ‐laying strategies ofAe. atropalpus exposed to standard (non ‐diapausing) rearing conditions and diapause‐inducing conditions and tested th...

Managing plague on prairie dog colonies: insecticides as ectoparasiticides
ABSTRACTHuman health practitioners and wildlife biologists use insecticides to manage plague by suppressing fleas (Siphonaptera), but insecticides can also kill other ectoparasites. We investigated effects of deltamethrin and fipronil on ectoparasites from black ‐tailed prairie dogs (Cynomys ludovicianus, BTPDs). In late July, 2018, we treated three sites with 0.05% deltamethrin dust and 5 sites with host ‐fed 0.005% fipronil grain. Three non‐treated sites functioned as experimental baselines. We collected ectoparasites before treatments (June‐July, 2018) and after treatments (August‐October, 2018, June‐July, 2...

Herbicide treatment alters the effects of water hyacinth on larval mosquito abundance
ABSTRACTInvasive aquatic weeds are managed with herbicides to reduce their negative impacts on waterways in many areas, including the California Delta Region. Herbicides create a dynamic environment of living and decomposing plant matter that could affect larval mosquitoes and other invertebrates, such as their predators and competitors. Our objective was to compare the number of larval mosquitoes in water or water hyacinth, before and after an herbicide treatment. We created replicated pond mesocosms with water hyacinth, water hyacinth treated with glyphosate and an oil adjuvant, open water, and water with glyphosate plus...

Horizontal distribution affects the vertical distribution of native and invasive container ‐inhabiting Aedes mosquitoes within an urban landscape
ABSTRACTThe vertical dimension constitutes an important niche axis along which mosquitoes may adjust their distribution. Here, we evaluated whether the vertical distribution of container ‐inhabitingAedes mosquitoes differs along a gradient of anthropogenic land ‐use intensity within an urban landscape. Using a pulley system, we hung oviposition cups at three heights (ground level, 4.5, and 9 m) and in three habitats: forest, park, and a built environment. We hypothesized that mosquito abundance and diversity would be highest in the least disturbed forest habitat, decrease in the park, and be lowest at the UNC‐Greensb...

Aedes albopictus oviposits with other Aedes species in artificial oviposition cups: a case study in Knox County, Tennessee, U.S.A.
ABSTRACTInterspecific associations between two mosquito species can lead to effects such as competition, species displacement, and species stability. To better understandAedes albopictus (Skuse) and otherAedes species, we monitored eggs in artificial oviposition cups (ovitraps) within Knox County, TN, U.S.A., during the 2016 and 2017 mosquito seasons. In 2016, one black and one white ovitrap were placed at 18 sites for 21 weeks, while in 2017 black and white ovitraps baited with grass ‐infused or deionized water were placed at 11 sites for nine weeks. Eggs were identified to species and resulting counts were used to dete...

Mosquito community composition and abundance at contrasting sites in northern South Africa, 2014 –2017
ABSTRACTMost data on species associations and vector potential of mosquitoes in relation to arboviral infections in South Africa date back from the 1940s to late 1990s. Contextual information crucial for disease risk management and control, such as the sampling effort, diversity, abundance, and distribution of mosquitoes in large parts of South Africa still remains limited. Adult mosquitoes were collected routinely from two horse farms in Gauteng Province; two wildlife reserves in Limpopo Province, at Orpen Gate in Kruger National Park (KNP) and Mnisi Area in Mpumalanga Province between 2014 –2017, using carbon dioxide...

Triatoma brasiliensis species complex: characterization of the external female genitalia
ABSTRACTTheTriatoma brasiliensis complex is composed of six species (Triatoma bahiensis, T. juazerensis, T. lenti, T. melanica, T. petrocchiae, andT. sherlocki) and two subspecies (T. brasiliensis brasiliensis andT. b. macromelasoma). Phylogenetic studies have shown that it is a monophyletic group, but the morphological relationships among the members can be better understood. We applied a tool of high resolution based on morphology to identify details that characterize the female genitals for each member of this group. The external genital structures of five to fifteen females of each taxon were analyzed. Insects had thei...

Influence of light and kairomone baiting systems on trap collections of biting midges in southern Sweden
The objective of this study was to determine how the baiting system used in traps (UV, incandescent light, incandescent light with CO2, and incandescent light with CO2 and 1 ‐octen‐3‐ol) influences estimates of midge population abundance, parity, and diel activity. This was achieved through a standardized trapping protocol conducted in three habitats in Sweden. UV light traps caught the mostCulicoides species and moreC. obsoletus complex females than incandescent light traps. Traps baited with CO2 plus 1 ‐octen‐3‐ol caught more femaleC. impunctatus than incandescent light traps. No consistent effect of bait typ...

Elimination of Aedes aegypti in northern Australia, 2004 –2006
This report details the methods and results of the detection and subsequent elimination activities that were carried out between 2004 and 2006, returning the NT to its dengue vector ‐free status. There have been very few successfulAe. aegypti elimination programs in the world. This purposeful mosquito elimination for Australia was officially declared on 5 April 2006.

Evaluation of boric acid as toxic sugar bait against resistant Aedes aegypti mosquitoes
This study evaluated insecticide delivery through toxic sugar baits (TSB) and resulting mortality of susceptible and resistant strains ofAedes aegypti. TwoAe. aegypti strains were evaluated using a 1% boric acid TSB: the susceptible Orlando 1952 (ORL) strain and the resistant Puerto Rican (PR) strain. The TSB resulted in high mortality for both ORL and PR strain ofAe. aegypti. Average mortality of female mosquitoes given TSB was 90.8% for PR and 99.3% for ORL. Our study suggests that targeting resistant mosquitoes with ingestible insecticides through TSBs could be a viable alternative to current mosquito control strategies...
