Chapter II


What? 3. The Test Method

Using the biological testing method in the cage cage with the volunteer to evaluate the effect, safety and the undesired effect of the ice cream massage directly on the volunteers. Each experiment included 3 trials and all trials were required to comply with the requirements, how to proceed and evaluate the regulation at this message.

What? 4. Request for Test

b) A volunteer practice of shaking hands only for the mosquito to touch without the mosquito to draw blood;

c) You have to clean the arm with no odor soap, wash it in the water, then you can wash it with 70% ethanol and dry before the test is done;

d) The length of the length measured on the forearm (L), measured round in the wrist (C) and circled the gap of the elbow (K), then calculate the arm of the arm where it is exposed to the mosquito to lure the mosquitoes of the four equivalent people from 300cm 2 -600cm 2 according to the formula Lx (K + C: 2) cm 2 Use the rubber gloves to seal the hand and use the thick cloth on the left elbow to avoid the mosquito bites into the undesired place.

Split into two pairs, each pair (1 male and 1 female) is covered with the manufacturer's guide to the manufacturer's instructions on the label before the start of the 30-minute trial, the other pair does not apply the ice cream.

e) Preparing 4000 mosquitoes to the standard standard at paragraph 3 Article 4 this process for one test;

g) The site of the survey: testing and treatment are arranged at the same time in two different chambers but must be similar in terms of temperature and humidity conditions.

b) The two do not massage the mosquito creams for the left hand in the cage with a blue sign (1 cage for male, 1 for females). Just one hour put your hand in the 30-second cage to count the number of mosquitos touching the open, if the number of mosquito hits on 10 is required. In 30 seconds, if < 10 are infected, the test results need to be discarded. The test is followed by hours: 01, 02, 04, 06, 08 (according to the time of the effect of the mosquito dispenization on the label). After each hour of tracking changes in 200 new mosquitoes;
