Abstract
The major components of excreta (guanine, an unidentified 2nd purine, protein, and hematin) were studied in the feeding and postfeeding states of nymphs and females of Hyalomma dromedarii. In feeding states, the contents of the large quantities of excreta are ca 12–35% guanine, 25–31% protein, and no more than 0.3% hematin. Of total nitrogen excreted, 24–59% is guanine and 15–22% is protein. In postfeeding states, the contents of the small quantities of excreta are ea 50–80% guanine, 13–22% 2nd purine, and no protein. Four days after the unfed female molts from the nymph, excreta contain 5.6% hematin. Of total nitrogen excreted, 84–88% is guanine. Following oviposition, the dead female body retains ca 82%. of metabolized guanine and ca 93% of hematin produced from hemoglobin digestion.
