초록

Carbofuran (2,3-Dihydro-2,2-Dimethyl-benzofuranyl methyl carbamate)와 Diazinon (0,0-Diethyl-0-(2-isopropyl-4-methyl-6-pyrimidinyl) phosphorothioate)을 10:0, 9:1, 8:2, 7:3, 6:4, 5;5, 4:6, 3:7, 2:8, 1:9, 0:10의 비율로 혼합하여 거세미나방 3냉기유충의 가운데 가슴등판에 $1.0{\mu}l$씩 국소처리 하였을 때, 이들의 연합독작용을 평가하였다. Carbofuran Diazinon을 혼합하였을 경우 거세미 나방 3령기유충에 대해서 협력작용(Synergism)을 나타내었으며 Carbofuran과 Diazinon을 4.8 : 5.2의 비율로 혼합하였을 때 최대의 협력효과(Synergistic effect)를 얻을 수가 있었다.

Abstract

Some experiment were conducted to evaluate the joint toxic action of carbofuran(2,3-Dihydro-2, 2-dimethyl-benzofuranyl methyl carbamate) and diazinon (0.0-Diethyl-0-(2-isopropyl-6-methyl-e-pyrimidinyl)-0-thionophosphate) against 3rd-instar larvae of the common cutworm, Agrotis fucosa (Butler). Acetone solutions of carbofuran or diazinon or mixture of these two insecticides, were topically applied to the mesonotum of the insect in a constant volume of $1.0{\mu}l$ per larva by means of Burkard microapplicator. Joint toxic action of carbofuran and diazinon for 3rd-instar larva of common cutworm was synergistic. The maximum synergistic effect might be obtained when the ratio of carbofuran to diazinon was 4.8 : 5.2.
