Stegomyia albopicta biting human skin

This mosquito is common in Japan without Northern Tohoku and Hokkaido districts.

Armigeres subalbatus biting human skin

This mosquito is called ''Big Armigeres'' in Japan.

I dislike mosquito bites, so I have studied mosquitoes and I have tried to produce new trap or new repellents. Moreover, I hoped to answer questions about mosquitoes, for example, which person is easy to be bitten. So I tested volunteers and estimated rank of easiness to be bitten by mosquitoes. In Japan, many people are troubled by mosquito bites in summer. Japanese people are mainly bitten by Ae. albopictus and Cx. pipiens pallens. Therefore, they use mosquito coils, mosquito liquid and mat including pesticides. On the other hand, Japanese laboratories of medical entomology have rapidly been changed into other laboratories or disappeared. Laboratories dealing with mosquitoes are very few. However, risk of invasion by dengue fever, malaria, West Nile Virus and yellow fever still exists even in Japan. Japanese pest control operators mainly fight with cockroaches and mice, and seldom execute mosquito control. Operators from self-government body or pest management company simply spray trees with pesticides.
I studied mosquitoes in Toyama Medical and Pharmaceutical Univ. in Japan. However, this laboratory had already changed into infectious diseases laboratory without medical entomology.
I wish to start mosquito control service, and sell goods against mosquitoes.

There is no room for studying mosquitoes and providing sufficient information for mosquitoes. I have no fund and cooperators. I should work with another business.
If someone comes to Japan and helps me with business: for example, mosquito control, selling control devices, please send email to me:
( My dreams are saving people from mosquito bites all through the year, and building pest museum (big dream); particularly including mosquitoes.
