Ultrastructural changes in the midgut epithelium of unfed lone star ticks with increasing age.
The gross morphology of the gut epithelium of adult lone star ticks ( Amblyomma americanum ) (L.) reared in the field was examined at 2-month intervals as ticks increased in age for 1 year.Expand

Age-related changes in midgut ultrastructure and surface tegument of unfed adult lone star ticks
Changes in midgut ultrastructure and surface tegument were examined in two laboratory-reared populations of unfed, adult, lone star ticks. Many solitary, electron-dense, iron-containing siderosomesExpand

Immunohistochemical localization of adenosine 3':5'-cyclic monophosphate in female ixodid tick Amblyomma americanum (L.) salivary glands.
Localization of adenosine 3':5'-cyclic monophosphate (cyclic AMP) in alveoli of salivary glands of female Amblyomma americanum (L.) was accomplished with an indirect immunofluorescent technique.Expand

Sodium, Chloride, and Water Balance in Feeding Gulf Coast Ticks, Amblyomma maculatum (Koch)
Whole body water and concentrations of Na+ and Cl− in the whole tick, gut content, hemolymph, and artificially induced oral secretion (saliva) of pre-fed and engorging females of the Gulf Coast tick,Expand

The transepithelial electrical potential developed by the isolated gut of the tick, Amblyomma maculatum (KOCH)
Abstract 1. Gut tissue obtained from the replete female Gulf Coast tick, Amblyomma maculatum, maintains a small transepithelial potential difference, lumen negative to the haemolymph side when theExpand
