Changes in Total Hemolymph and Ovarian Proteins during Oogenesis in Argas (Argas)hermanni (Acari: Argasidae)

摘要

Changes in the total protein concentrations in the hemolymph and ovaries of fed,mated female Argas (Argas) hermanni Audouin during oogenesis and in the hemolymph of males were studied. There was a decline in the total protein level in hemolymph of mated ticks for 2 d after feeding. This decrease was followed by an increase, reaching a maximum on day 6 in males and days 5 and 6 in females. Protein levels in the hemolymph of female ticks were higher than that of the male during the period of vitellogenesis and onset of oviposition (3-6 d after feeding). At the end of the oviposition period (day 20), the protein level in the hemolymph decreased, approaching that of the male. These data suggest an increase in the demand and use of proteins in the hemolymph of females by the developing oocytes. The increase of the hemolymph proteins in the females coincided with an increase of the ovarian protein level, ovarian weight, and the number of mature oocytes inside.
