应用绿僵菌防治东亚飞蝗田间试验

本文首次报道应用绿僵菌Ｍｅｔａｒｈｉｚｉｕｍｆｌａｖｏｖｉｒｉｄｅ防治东亚飞蝗Ｌｏｃｕｓｔｍｉｇｒａｔｏｒｉａｍａｎｉｌｅｎｓｉｓ的田间试验结果。试验在１９９４年夏季于天津北大港水库蝗区进行。绿僵菌孢子粉用精炼植物油稀释调制成不同浓度的油剂，供试验喷雾之用。田间试验在处理后第１０天校正死亡率为８１．５％；人工模拟小区试验在第１０天供试虫全部死亡。初步结果表明在一定条件下使用绿僵菌油剂防治东亚飞蝗可获得良好效果

FIELD EXPERIMENT ON LOCUST CONTROL BY METARHIZIUM FLAVOVIRIDE IN CHINA

This is the first report on field experiment about biological control of oriental migratory locust, Locust migratoria manilenses (Meyen), by using oil formulation of Metarhizium flavoviride in China. The experiment was conducted in the field, where locust occurred naturally, near Beidagang Locust Control Station, Tianjin, in northern China in June of 1994. In a field test the mortalities of 49 1%, 70 2 and 82 9% were observed on 6, 8 and 10 days after treatment, respectively. While in a simulated plot test 100% mortality was obtained on 10 days after treatment. The preliminary results showed great potential on biological control of locust using Metarhizium in China.
