Abstract

|
|
Many synthetic insecticides have been used to protect one´s safe living from physical and mental damage and economic loos since the Second World War. As the result of using insecticides many insects have attained resistance to the insecticides that they have been exposed to.
We import and use insecticides without exact information of what concentration the farmers should use. So many insects have attained resistance in Korea, and we need new insecticides that cannot be resisted.
This study was carried out on the effect of insecticides made from plants which have killing effect on insects.
The author made and tested the self-made insecticides on hourse-flies (Musca domestica vicina L.) and cackroaches (Blattella germanica).
The results as following;
1. High effectctiveness of malathion was observed on house-flies and cackroaches, but showed low resistance power on sumithion and DDVP.
2 Fluid extraction of Pursatilla Koreana and Ranunculus Tachiroei root showed killing effect on house-flies lavae.
3. With the same fluid extraction there is no killing effect on cackroaches.
