Mosquito Larva Preservation Larvae is one of the phases of a mosquito in its life cycle. Each species of mosquito also exists namely different characteristics of larvae. The following are the differences between the larvae of each species : a. Mosquito larvae Culex sp. :  Chiffon is long and slim  Hairtuft or feather fluff more than one  Comb teeth or spines at the end of the abdomen in more than one row b. Mosquito larvae Aedes sp. :  Chiffon is fat and short  Hairtuft or featherphone only one pair  Comb teeth or spines at the end of the abdomen are only one row c. Anopheles sp. mosquito larvae. :  Doesn't have a siphon d. Mansonia sp. mosquito larvae. :  At the tip of the font there ispiercings valves or hook Which sharp and blackish brown in color conical chiffon, fat and short. METHOD Wet pickling OBJECTIVE 1. For identification And to know the morphology of mosquito larvae. 2. For collection. TOOL 1. Petridish cup 2. Pipettes 3. Glass objects 4. Cover glass 5. Plastic spoon/stick 6. Microscope MATERIAL 1. Hot water 2. KOH 10% / NaOH 10% 3. Alcohol levels of 30%, 50%, 70% and absolute 96% 4. Entelan 5. Xylol PROCEDURE 1. Prepare mosquito larvae, make sure the mosquito larvae are still alive. 2. Mosquito larvae / larvae are killed with hot water. 3. Prepare a petridisk (6 plates) each filled with:  10% KOH / NaOH solution  alcohol 30%  50% alcohol  70% alcohol  absolute alcohol 96%  xylol solution. 4. The first stage, put the larvae in a 10% KOH / NaOH solution functions to thin (chitin) until transparent. So the inside larvae can be seen. 5. The second stage, put the mosquito larvae in 30% alcohol, 50%, 70%, and 96% absolute alcohol, let stand for 5 minutes at each stage alcohol 30% - 96%. This second stage is called the dehydration stage which aims to secretes fluid contained in the larva's body. So that the larvae durable. 6. The third stage, put the dehydrated larvae into xylol for 1 minute, this stage is intended to clean the alcohol from larval body as well as to stop the action of alcohol. If xylol too long and the larvae will shrivel. 7. Fourth stage, lift the mosquito larvae from the xylol solution and place them on glass object. Make sure when lifting the larvae that they are not damaged. 8. Look under the microscope to identify the larvae. 9. Once identified, cover the larvae on a glass object with a cover glass which has been given entelan. 10. Label and store in the preparation box.
