“…5). This is in agreement with data from the tick H. dromedarii (Kamel et al, 1982). However, a significant decrease in B. microplus VT content during the first 4 days of embryogenesis was verified.…”

“…These data suggest that maternal-driven processes are replaced by embryonic zygotic expression after cellularization of the blastoderm. A steady increase in total RNA content at the beginning of embryonic development has also been described for Tribolium confusum and for the tick Hyalomma dromedarii (Amnai-Devi et al, 1963;Kamel et al, 1982).…”

Energy homeostasis is an essential process during oogenesis, nutrients are required for suitable embryonic development, and recently, studies have investigated metabolic activity during this process. This work aims the investigation of dynamics of energy source utilization of Rhynchophorus palmarum during embryogenesis. For this, we first evaluated the mobilization kinetics of the lipids and glycogen. Thereafter, the synthesis of RNA, protein, and the involvement of enzyme of the glycolytic and pentose-phosphate pathways. Results showed that lipid content decreased in contrast with the lipase activity. The total glycogen amounts it was partly consumed and the glucose content increased, but then values remained stable until hatching. Total RNA content increased, and no significant changes in total protein content were observed. A study of the glycolytic pathway data showed activity of hexokinase and pyruvate kinase at the beginning of embryogenesis. Furthermore, glucose-6-phosphate formed is driven into the pentose-phosphate pathway viewed the high activity of glucose-6-phosphate dehydrogenase. Finally, these results showed that mobilization of different energy sources together with different enzymatic activities has an important role in embryonic development of R. palmarum .

“…We suggest that the three fractions represent metabolic steps of the major haemovitellin present in the egg of the cattle tick B. microplus. Similar haemoprotein interconversion was observed with Hyaloma dromedarii during its embryogenesis (Kamel et al, 1982). The presence of vitellin in different organs of Rhipicephalus sanguineus and Dermacentor variabilis (Rosell and Coons, 1990) as well as during distinct developmental stages of D. variabilis (RosellDavis and Coons, 1989) was noticed.…”

Changing patterns of vitellin-related peptides during development of the cattle tick Boophilus microplus

The major components of protein extracts from the cattle tick Boophilus microplus eggs and larvae of various ages were characterized by molecular sieving chromatography, ion exchange chromatography and SDS-PAGE. The fractions analysed showed a changing chromatographic pattern development. A serum raised against the components of a fraction showing characteristics of vitellin strongly reacted in Western blots with the major peptides of extracts from eggs, larvae, gut and ovary. Comparison of patterns obtained by electrophoresis in non-denaturing PAGE, stained with Coomassie blue or with benzidine/hydrogen peroxide, revealed that the major proteins of these extracts are haemoproteins, possibly in different aggregation states or heterogeneous in composition.
