“…In the present work, the protein level in the HL of the female A. persicus decreased once more after the completion of oviposition suggesting its consumption by developed oocytes. This is in agreement with previous studies in ticks which have shown that the increase of total HL protein level during vitellogenesis and oviposition was followed by a progressive decrease in HL protein at the end of oviposition in female B. microplus (Tatchell, 1971), R. sanguineus (Araman, 1979), A. hermanni (Shanbaky et al, 1990b) and O. erraticus (Yousery, 2011).…”

“…The total protein concentration in the HL of mated fed adult A. persicus decreased immediately and up to the 2 nd and 3 rd daf in the females and males respectively and was insignificantly different in both sexes up to the 2 nd daf. The results conform to those in other argasid ticks (Shanbaky et al 1990b andYousery, 2011). The observed decrease could be attributed to a dilution of the HL by an influx of excess water from the blood meal and the marked increase in the HL volume as was observed by Hefnawy (1972) and Hesse (1984) in the argasid, A.arboreus and O.moubata.…”

“…This period coincided with the rapid phase of digestion reported in other argasids (Tatchell, 1964;Grandjean, 1973 andElshoura, 1988). Changes in concentration of HL total protein in A. persicus followed similar patterns to those found in A. hermanni (Shanbaky et al, 1990b) and O. erraticus (Yousery, 2011).…”

“…The significant increase in the HL protein level in the female than in the male A. persicus (3-7 daf) and in previously studied argasids, A. hermanni (Shanbaky et al, 1990) and O. erraticus (Yousery, 2011) reflects the increasing demands for proteins during vitellogenesis in the female (Shanbaky et al 1990c). In A. hermanni, the increase of the concentration of the HL proteins in the females (3-6 daf) positively correlated with an increase of the ovarian protein level, weight and the number of mature oocytes which suggested an uptake of HL protein by the ovaries (Shanbaky et al, 1990b). Furthermore, the levels of HL protein and midgut proteases were higher in the female than male O. erraticus pointing to an increased digestion of protein in the female than in male tick to supply needs of the female (Yousery, 2011).…”

“…In the present work the concentration of the total protein in the ovaries of the mated females A.persicus gradually increased after feeding to reach the maximum level on 5-7 th daf which lagged behind the maximum in the HL (4-7 daf) and might be attributed to uptake of the HL protein and/ or increased synthesis in the ovary proteins. An increase in the level of ovary protein was observed by Shanbaky et al (1990b) in the mated engorged A. hermanni. The authors demonstrated that the period of the increase of the ovary protein level coincided with the progress of vitellogenesis (3-6 daf) as determined by the weight of the ovaries and the number of mature oocytes.…”

Changes in the total protein titer in the haemolymph (HL) and ovaries (Ov) of mated fed normal and Lufox treated female Argas persicus during the reproductive cycle and in the HL of normal male were studied. Tick engorgement was followed by an intial drop of the HL total protein concentration immediately and up to the 2 nd and 3 rd day after feeding (daf), then by a gradual increase on next days to reach maximum on 4-7 and 6-7 daf in the female and male, respectively. The level in the female HL was much higher than that in the male during vitellogenesis and the onset of oviposition. In the ovaries of normal female the total protein level increased gradually immediately up to 2 daf and evidently on 3 daf to reach a maximum on 5-7 daf. The protein level in the HL and ovaries decreased after the completion of oviposition (20 daf). Topical application of a single dose of 50 ppm Lufox on the mated female A. persicus on the 3 rd daf interfered with protein production causing a significant reduction in the total protein level in the HL (43.04-55.57%) and ovaries (36.47-46.43%) during vitellogenesis on 4-7 daf and in eggs (15.38%) freshly deposited by the treated female. Also, application of Lufox on the 3 rd daf altered the normal pattern of change in the level of HL and ovary total protein during the reproductive cycle by preventing any appreciable increase in the level on next days (4-7 daf) where the level remained constant in the ovaries and even decreased in the HL (4-5 daf).
