stem of T. crispa has been used by traditional folklore for
various therapeutic purposes such as treatment for diabetes,
hypertension, stimulation of appetite and protection from
mosquito bites. Also it was also used as an anti-parasitic agent
in both man and domestic animals [17], [18]. In this study, the
response of pomelo to the treatment of wood vinegar and
organic substances from plants was studied against S. dorsalis
and P. citrella. The treatment of T. crispa was the highest
effective control against both S. dorsalis and P. citrella.
It causes a success reduction in pest populations on treated
pomelo when compared to control treatment. In India, [19]
reported that significant reduction in S. dorsalis populations
by using entomopathogens Fusarium semitectum in pepper
fields. In addition, [20] reported that the applications of oil
are suitable methods to help reduction the populations of P.
citrella in Florida. Moreover, [21] indicated that utilization of
natural sources for bio-pesticides has increased. S. collinsiae
root extracts have a great potential in agro industries and has
been used as a bio-pesticide in rural areas
