Mosquito

[Left] A knee of Dr. Sato on July 14, 1995, when we surveyed vegetation on ice wedges along Kolyma River. Since I took the photo after many mosquitos escaped, the enemies were not so many. [Right] It was fine weather near Kolyma River on July 18, 1995. I measured methane flux with Drs. Sato and formely JR Hokkaido Campaign Girl. We prepared so-called fully-protective wear, including mosquito netting, raincoat, thick gloves, and rubber boots.

Action

Fully protective wear is the best way for health, although we feel sunsick. However, we are exhausted for a short time as if we took a sauna.
We usually put DEET (C12H17NO), that is a super-strong rejectant, on our skins when we stay in Alaska. DEET melts plastic. In fact, a band of my wristwatch was denatured. However, we can not stop using DEET like a drug after we understand the overwhelming efficacy.
Although we should seek immediate medical attention if the symptom is serious, we may not be able to go any clinics ASAP when we stay in the study sites. It is better that we should prepare accurate medicines.

Punkie

We hate punkie more than mosquito when we survey in Hokkaido.

Gadfly

Stop sucking blood from a wound. I have ever felt nauseating without bottle-ache, because of sensitiveness.

I poked something like a dung by a stick in Abashiri, because I thought the insects around the dung were flies. I was slow to realize that it was wasp! Oh boy.
