Detection of Anaplasma spp. and Bartonella spp. from wild ‐caught rodents and their ectoparasites in Nakhon Ratchasima Province, Thailand
The objective of this study was to investigate evidence of emerging anaplasmosis and bartonellosis in rodents from endemic areas of Nakhon Ratchasima, Thailand. Rodent trapping was undertaken in 13 sub ‐districts of Muang District. The live‐capture traps were set up in three locations of selected scrub typhus patient houses for three consecutive nights. Wild‐caught rodent whole blood samples and associated ticks and fleas were collected and tested forAnaplasma spp. andBartonella spp. In addition, heat maps using GIS software were used to determine the density of infection of positive wild ‐caught rodents. A total o...

Molecular detection of Bartonella henselae, Bartonella clarridgeiae and Rickettsia felis in cat and dog fleas in Tenerife, Canary Islands, Spain
ABSTRACTThe cat fleaCtenocephalides felis is the main vector ofBartonella henselae andBartonella clarridgeiae, the causative agents of cat ‐scratch disease (CSD) and the spotted‐fever agentRickettsia felis. In spite of their worldwide distribution, there are no data on the occurrence of CSD ‐causingBartonella species or the prevalence ofRickettsia species in the Canary Islands, Spain. Therefore, the aim of our study was to screen cat and dog fleas for both pathogens. A total of 128C. felis from cats and dogs were screened forBartonella andRickettsia by PCR.Bartonella henselae (2.3%) andB. clarridgeiae (3.9%) were fou...

Analysis of Anopheles messeae s.l. intron gene polymorphism associated with imidacloprid resistance
ABSTRACTDue to their high solubility and stability, neonicotinoid insecticides are able to accumulate in water bodies, affecting aquatic organisms. The aims of this study were to evaluate resistance (LC50) ofAnopheles messeae s.l. (Anopheles messeae andAn. daciae) to the neonicotinoid imidacloprid and to search for genetic markers associated with insecticide resistance. The LC50 values of these species in the collections during 2017 and 2018 were indistinguishable and were in the range of 0.027 –0.051 mg/l. In general, the LC50 values of the mosquitoes were comparable with values of other mosquito species of theAnopheles...

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...

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...

Semi ‐field evaluation of a modified commercial My Mosquito Deleter larval trap with sticky paper against Aedes aegypti
Aedes aegypti (L.) is a major vector of yellow fever, dengue, and Zika viruses, and its management can be difficult, especially in situations where insecticide usage is restricted and resistance is present. Traps and trapping techniques have mostly been used for monitoring populations of adult mosquitoes, but several commercially available traps have been evaluated and used to reduce nuisance populations of adult mosquitoes (Kline 2006). Suppression ofAe. aegypti, in particular, requires a suite of integrated control measures. One measure gaining more attention is to attract and kill gravid females by exploiting their ovip...

Wing size and parity as markers of cohort demography for potential Anopheles (Culicidae: Diptera) malaria vectors in the Republic of Korea
ABSTRACTWing lengths of parous (P) and nulliparous (NP) PCR ‐identified femaleAnopheles belenrae, An. kleini, An. pullus, andAn. sinensis were determined from weekly trap collections at Camp Humphreys (CH), Ganghwa Island (GH), and Warrior Base (WB), Republic of Korea (ROK) during Jun ‐Oct, 2009. Wing length was greatest at the beginning and end of the study period. Wing length of NPs tended to be less than that of Ps before the period of maximum greening (Jul‐Aug) but greater thereafter. Larger specimens tended to be Ps, and weekly wing length of Ps appeared less variable th an NPs, possibly due to selection. A bimo...

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...
