Susceptibility of Lone Star Ticks to Chlorypyrifos and Diazinon, 1981

Insecticide and Acaricide Tests, 1982
Abstract A disposable pipette method adapted from Kigaye, M. K., and Matthysse, J. G., 1973, Bull. Epizoot. Dis. Afr. 21: 429-35, was used to assay acarlcides against the active life stages, i.e., larva, nymph, adult males and adult females.

Microbial communities and interactions in the lone star tick, Amblyomma americanum

Molecular Ecology, 2008
AbstractTo quantify microbial composition and interactions, we identified prokaryotic communities in the lone star tick (Amblyomma americanum) based on 16S rRNA gene sequences and direct probing. The lone star tick is the vector of emerging diseases and host to additional symbionts of unknown activity, and is representative of other blood‐sucking ...

Cold-Hardiness of a Laboratory Colony of Lone Star Ticks (Acari: Ixodidae)

Journal of Medical Entomology, 1996
The cold-hardiness of a lone star tick, Amblyomma americanum (L.), laboratory colony was characterized. Fed and unfed larvae, fed and unfed nymphs, and unfed adults did not survive exposure to -17 degrees C for 7 d. After an 8-d exposure to -10 degrees C, adults tolerated cold better than immatures and unfed specimens fared better than fed ticks ...

Mating Behavior and Reproduction of the Lone Star Tick,Amblyomma americanum

Annals of the Entomological Society of America, 1970
When a bovine stanchioned in an enclosed stall and guinea pigs maintained in the laboratory were used as hosts for adult Amblyomma americanum (L.), individual male ticks were observed to inseminate 18–37 females in 43–127 days after feeding for 7–32 days before the 1st mating. Preoviposition period of replete females averaged 6.5 days (range 3–10 days).

Control of fluid secretion by isolated salivary glands of the lone star tick

Journal of Insect Physiology, 1975
Abstract Adrenaline, noradrenaline, cyclic-AMP, and theophylline stimulated salivary fluid secretion in glands isolated from rapidly engorging females of the lone star tick, Amblyomma americanum . Cyclic-AMP and theophylline effectively initiated secretion only after the glands were pre-incubated and pre-stimulated to secrete with adrenaline ...

Acaricide Screening for Control of Lone Star Tick, 1983

Insecticide and Acaricide Tests, 1984
Abstract Engorged females of Amblyomma americanum (L.), the lone star tick, that detached normally from cattle no more than 24 h earlier were used in dipping tests. Ticks wer washed, blotted dry, and sorted into groups of 8; each group was placed into an individual dipping cage.

Cattle, Lone Star Tick Animal Screen, 1982

Insecticide and Acaricide Tests, 1983
Abstract Hereford yearling cattle that are artificially tick infested are treated with new insecticides found to be effective acaricides in-the acaricide screening tests. Hair from the cattle is removed from the back midline down the side so that an area about 0.1m on each side of the yearling is close clipped.

Influence of Deer Exclusion on Populations of Lone Star Ticks and American Dog Ticks (Acari: Ixodidae)

Journal of Economic Entomology, 1986
A 2.43-ha deer exclosure was constructed in the Tennessee Valley Authority’s Land Between The Lakes in 1977–78 to study the effects of deer exclusion on the lone star tick, Amblyomma americanum (L.). Tick populations were monitored with dry ice in 1978 and 1979, and with dry ice and drags in 1982.

BULLIS FEVER (Lone Star Fever—Tick Fever)

Journal of the American Medical Association, 1943
During the spring and summer of 1942 many patients suffering from various acute febrile diseases were admitted to the contagious disease section of Brooke General Hospital, Fort Sam Houston, Texas. Most of these illnesses presented no great diagnostic problem, being recognized as seasonal diseases, such as infections of the upper respiratory tract ...
