6 EFFICIENCY
Following are the effectiveness of "Crown Roselle Repellant Wax"
against the cockroaches.
(1) Testing Test (Own Research)
The transition of Knock Down Ratio by tracer has been
studied to ascertain the effectiveness of "Crown Roselle
Repellant Wax" against CHABANE cockroaches by using
the touching test whereby ten cockroaches in 8 centimeters
across ring were touching with the application on the floor.
(Figure 6.1)
To determine, the knock down ration means percentage of
the CHABANE cockroaches fall or swoon in the all objects.

(2) Repellency Test (Own Research) See Figure 6.2
Figure 6.2 illustrates that the shelters were set up and the
objects were put at the center of 15cm x 12cm application
plate in the 60cm x 60cm x 20cm height test box. Twenty
cockroaches of both genders are held in the box and the
number of cockroaches living in each shelter were counted
in order to ensure the performance of the repellency of
"Crown Roselle Repellant Wax". Water and food are
provided in every shelter and the box is opened.

The difference of the total number of cockroaches in each
day shows that the cockroaches which stayed at the outside
of the shelter or died are not counted.
As the result from this research, it is clear that "Crown
Roselle Repellant Wax" has distinct repellency against
cockroaches.
(3) Repellency Test (At Official Research Center)

Hygienic Sciences Institute) for "Crown Roselle Repellent
Wax" against cockroaches, it has been recognized that
"Crown Roselle Repellant Wax" is highly effective and
efficient under severe condition in the house test.
7 STABILITY (SUBSTANTIVITY) OF "CROWN ROSELLE
REPELLANT WAX"
The substantivity for the active ingredient of "Crown Roselle
Repellant Wax" has been tested under several conditions of the
weather.
The data in Table 7 were investigated using Gas
Chromatography(GC).
Table 7
Test Conditions Substantivity Ratio (%)
