Use of diatomaceous earth to control nymphal American dog ticks, Dermacentor variabilis Say (Acari: Ixodidae): laboratory to simulated field experiments.

Diatomaceous earth (DE) recently was shown to rapidly kill ticks. Proof of concept for use of DE to kill the American dog tick, Dermacentor variabilis, the most widely distributed native three-host tick in North America, has not been investigated. Unfed D.

Orientia, Rickettsia, and the microbiome in rodent attached chiggers in North Carolina, USA.

Chiggers are larval mites that pose a significant health risk globally via the spread of scrub typhus. However, fundamental studies into the bacterial microbiome in North America have never been considered. In this investigation, chiggers were collected in the wild from two locally common rodent host species (i.

Non-Chemical Control of Nymphal Longhorned Tick, Neumann 1901 (Acari: Ixodidae), Using Diatomaceous Earth.

The longhorned tick (LHT), Neumann (Acari: Ixodidae), is a serious invasive pest in North America where its geographical range is expanding with high densities associated with commercial animal production. There are only a few chemical pesticides available for LHT control, which can lead to the evolution of resistant strains. Diatomaceous earth (DE) was shown to be effective in killing some important tick species but was not examined for LHTs.

Is There Utility in Preoperative Testing of Hemoglobin Before Primary Cheiloplasty?

Objective: To examine whether a preoperative hemoglobin of less than 10 g/dL is associated with a higher rate of perioperative complications.

Design: Retrospective review.

Setting: Tertiary academic hospital at Arkansas Children's Hospital of Little Rock, Arkansas.

Acaricidal Biominerals and Mode-of-Action Studies against Adult Blacklegged Ticks, .

Ticks in the USA are the most important arthropod vector of microbes that cause human and animal disease. The blacklegged tick, , the focus of this study, is able to transmit the bacteria that causes Lyme disease in humans in the USA. The main approach to tick control is the use of chemical acaricides and repellents, but known and potential tick resistance to these chemicals requires the discovery of new methods of control.
