1985-8年非洲大面积长期持续干旱之后降了雨,使蝗虫和蚱蜢虫口激增。从西部塞乃加尔和毛里塔尼亚到东部的伊朗,蝗虫和蚱蜢大发生。虽然用化学农药进行防治取得了成效,但费用昂贵,且影响环境,对蝗虫防治方法的重新评价已十分必要。因此1989年国际英联邦农业局(CABI)的国际生物防治所(IIBC)、国际热带农业研究所的生物防治研究中心(IITA-BCP)和萨赫勒国际干旱控制常务委员会的作物保护培训部(CILSS-DEPV)进行合作研究。主要目的是探讨应用真菌油剂配方防治蝗虫和蚱蜢的可行性。
After a long period of prolonged drought in Africa in 1985-8, it rained and the number of locusts and grasshoppers soared. Locusts and grasshoppers occur in Iran from Senegal in western Senegal and Mauritania to the east. Although the effectiveness of chemical pesticide control has been achieved, it is expensive and affects the environment. It is necessary to reassess the locust control methods. As a result, the International Institute for Biological Control (IIBC) of the International Commonwealth Agricultural Bureau (CABI), the IITA-BCP of the International Institute of Tropical Agriculture and the Crop Protection Training Division of the Standing Commission for Sahel International Drought Control (1989) CILSS-DEPV) for collaborative research. The main purpose is to explore the application of fungicide oil formulations to control locusts and grasshoppers feasibility.
