11. Summary of the new findings of the thesis
The project has added new data on the distribution, biological, ecological, and genetic characteristics of Triatoma rubrofasciata in central Vietnam. Of which, the male individuals comprise 11 pairs of autosomes and 3 sex chromosomes (1 Y, 1 X1, and 1 X2).
Detection of Trypanosoma conorhini and Trypanosoma lewisi for the first time in T. rubrofasciata in central Vietnam.
Provide new data on species-specific mitochondrial gene segments, Cyto-B and COII, for T. rubrofasciata.
Identify the T. rubrofasciata repellent properties of the natural essential oils of Severinia monophylla at a concentration of 0.5% in acetone.
12. Practical applicability, if any:
The research results have great impacts in theoretical and practical prevention of disease-transmitting insects; providing information on morphology, biological, and ecological characteristics of T. rubrofasciata so that people can recognize and prevent disease-transmission vector species - T. rubrofasciata.
13. Further research directions, if any
Continue to research and develop of molecular biology techniques for the detection of parasites in general and for detection of Tryp. lewisi and Tryp. conorhini in particular.
Further research on the epidemiological role of T. rubrofasciata to provide a complete and accurate information, and suggest effective prevention measures for this species.
Further investigate in-depth the mechanism of meiosis and chromosome set in the female individuals as well as the embryonic development of T. rubrofasciata.
Expanding the examination of natural active ingredients, especially essential oils, to find out the ones that inhibit the molting and development of blood-sucking bugs T. rubrofasciata without being toxic to humans.
In addition, conducting field trials of essential oil from Severinia monophylla.
