Container-breeding mosquitoes are important in public health due to outbreaks of Zika, chikungunya, and dengue viruses. This paper documents the distribution container-breeding mosquito species Mississippi, with special emphasis on genus Aedes. Five sites each 82 Mississippi counties were sampled monthly between May 1 August 31, 2016, 50,109 14 collected. The most prevalent widely distributed found was Ae. albopictus, being all counties, especially during July. A recent invasive, japonicus,...

Immatures of Amblyomma maculatum have historically been difficult to collect when not on an animal host, thus a definite seasonality the immatures has never determined. In this study, we made tick collections at two sites during 2012–2014. Site A (Oktibbeha County) in northern Mississippi, and B (Jackson southern were sampled from September-May October-May, respectively. Sampling was vegetation with 1 m2 weighted white corduroy drag cloth, dry ice traps, also novel method known as...

Abstract Environmental factors affect host-seeking behavior in ticks. In this study, 80 nymphal Amblyomma maculatum Koch were released an observation arena containing four different heights of broomsedge stems (Andropogon virginicus L.) anchored sand. Observations made over three days as to proportion ticks questing, questing height, and stem height distribution This scenario was replicated times with cohorts (n = per replicate) for each treatment combinations temperature humidity: High...

The tick, Amblyomma maculatum Koch (Gulf Coast tick), has recently been shown to be an important disease vector of both medical and veterinary concern. Although much is known about the behavior ecology adults, little immatures. Larval feeding on humans never demonstrated (and thus, there are no collection records from humans). In this experiment, 10 larval A. maculatum, americanum (L.) (a positive control), Dermacentor variabilis (Say) negative were applied forearms human volunteers (five...

: Almost nothing is known about the questing and dispersal behavior of immature Gulf Coast ticks (Amblyomma maculatum), a vector both medical veterinary concern. This experiment examined host-seeking (questing) marked, previously colonized, nymphal A. maculatum released in field plots rural Oktibbeha County, Mississippi during 2015. A total 500 (250 per replication) nymphs were painted 5 (50 each time). Observations then made times, approximately every 3 days, searching for from release...

Abstract In the 1930s, R. A. Cooley noted that Dermacentor occidentalis (Acarina: Ixodidae) and andersoni were closely related could hybridize. Decades later, James Oliver discovered crosses of variabilis, D. andersoni, could, on occasion, produce hybrids. A recent molecular analysis (both mtDNA nDNA) in our laboratory revealed certain specimens nested with parumapertus. Does this close relationship, along mito-nuclear discordance we have observed, mean parumapertus are a single species? By...

Dermacentor parumapertus Neumann (Acari: Ixodidae), a tick primarily associated with rabbits which occurs over much of the western United States, has fairly large north-to-south distribution, being found from central Idaho southward into northern Mexico. This mostly obscure species recently been focus attention due to discovery unique strain Rickettsia parkeri it appears closely related sp. in Atlantic rainforest Brazil. Historically, morphological variety this was reported literature based...

Dermacentor parumapertus Neumann (Acari: Ixodidae) is a rather obscure tick found on jackrabbits in the western United States and parts of Canada Mexico. Specimens from northern part their range are consistently different morphologically ones southern eastern (particularly west Texas), leading some researchers to declare form variety or subspecies. This study examined field-collected adult D. two main locations-Utah Texas-within its geographic distribution ascertain degree genetic divergence...

Ticks utilize a variety of strategies to mitigate water loss and enhance their off-host survival. This is the first report primarily tropical zone tick, Gulf Coast tick Amblyomma maculatum, vector Rickettsia parkeri, regulate by photoperiodic induction. Under short-day conditions (10 h:14 h L:D), rates are decreased. has positive effect on survival extending time it takes reach dehydration tolerance limit. When cycled between long- conditions, rate drops then returns faster after re-entering...

Ticks (subclass Acari) are closely related to mites, which known utilize invertebrates such as arthropods for feeding well phoresy. Therefore, it is reasonable assume that ticks may occasionally infest invertebrates. Indeed, there records of on in literature (Table 1). Amblyomma americanum (Lone Star tick) a tick frequently encountered the southeastern United States and an aggressive feeder (Goddard Varela-Stokes 2009), whose larvae will respond movement CO2 from respiration (Ginsberg Ewing...

Amblyomma americanum (L.) (lone star tick) is an aggressive, three-host tick that commonly found throughout the southeastern United States (Goddard and Varela-Stokes 2009, Vet. Parasitol. 160: 1–12). This utilizes array of vertebrates for hosts, including humans (Bishopp Trembley 1945, J. 31: 1–54), has even been demonstrated to imbibe hemolymph from invertebrates (Portugal Goddard 2015, Vector Ecol. 40: 202–204). Lone ticks are associated with multiple human pathogens recently have...
