흰불나방의 化學的防除에 관한 硏究 : Hyphantria cunea Drury = Studies on Chemical control of Fall webworm

국문 초록 (Abstract)

山林 害蟲인 흰불나방의 效果的인 化學的 防除法을 確立코자 殺蟲劑인 有機憐系의 DEP-Ec, PAP-Ec, MPP-Ec와 Carbamate系의 BUX-Ec, BPMC-Ec를 幼蟲 3령에 Morris法 處理로 얻은 殺蟲率을 Bliss의 probit法으로 分析, 다음과 같은 成績을 얻었다.
가) 1化期에 DEP-Ec는 MPP-Ec보다 相對效果의 比가 2.899倍 2化期도 BPMC-Ec보다 145倍의 상당한 效果기 있으며 BUX-Ec도 1化期에서 1.85倍 2化期에서 12.08倍의 傾向이 있었다.
나) 1化期 幼蟲 무게가 30.98±6.83mg 일 때 DEP-Ec, BUX-Ec 및 MPP-Ec의 LD??의 濃度는 0.00139%, 0.0022%, 0.00407%이며, 2化期 幼蟲 무게 34.583±5.265mg 일 때 DEP-Ec, BUX-Ec, MPP-Ec의 LD??의 濃度는 0.0002%, 0.0024%, 0.029%이다
다) 2化期는 1化期에 比하여 BUX-Ec, 0.0002%, BPMC-Ec 및 PAP-Ec는 0.015%, 그리고MPP-Ec는 매우 많은 抵抗性의 傾向이 있었다.
라) 驅除用 殺蟲劑로서는 DEP-Ec, BUX-Ec이며 1化期에는 0.00955, 0.01515, 2化期에는 0.0016%, 0.0163%의 濃度가 LD??이다.

The experiment was planed to establish the method of effective chemical control of the Fall webworm, (Hyphantria cunea Drury),
The insecticides treated here were the ditto system, carbamate system; the ditto system insecticides were DEP-Ec, PAP-Ec, MPP-Ec, and carbamate system were BUX-Ec, BPMC-Ec.
The insecticides were analyzed the Morris method in the 3rd age and the dota 잼 obtained by investigating the destroying ratio and the results obtained were as follows.
1) In the 1st instar, DEP-Ec was revealed rathes potency higher to 2.899 times as conyareded to MPP-Ec, In the 2nd instare DEP-Ec was higher to 145 times tham BPMC-Ec and BUX-Ec in The 1st instar was 1.85 times and was the tendency of 12.08 times in the 2nd instar.
2) As the weight of the 1st instar was 30.98±6.83mg, LD?? values of DEP-Ec was revealed 0.00139%, BUX-Ec 0.0022%, MPP-Ec was 0.00407% and the weight of the 2nd instar was 34.583±5.265mg, LD?? values of DEP-Ec was alss revealed 0.0002%, BUX-Ec was 0.0024%, BPMC-Ec was 0.029%.
3) Being compared the 2nd instar with the 1st instar relativl activity was revealed in BUX-Ec as 0.0002%, BPMC-Ec and PAP-Ec as 0.015% and MPP-Ec as rather high activity.
4) effective insecticides to extermimate the Fall webworm were DEP-Ec, BUX-Ec and LD?? valve was 0.0095%, and 0.015% respectively in the 1st instar and was 0.0016% and 0.0163% respectively in the 2nd instar.
