| 摘 要： | 在天津市大港区东亚飞蝗发生区，采用条带交替式超低量喷雾，施用蝗虫微孢子虫与卡死克防治东亚飞蝗，３个处理的卡死克（５％水剂）使用量均为１５０ｍｌ／ｈｍ２，微孢子虫使用量分别为１５×１０９、２２．５×１０９和３０×１０９孢子／ｈｍ２。处理时东亚飞蝗为３龄末盛期，虫口密度分别为２６．３８、１１．６３和２９．８８头／ｍ２。防治后第７天虫口减退率分别为８９．６５％、７５．９１％和８９．７６％，存活蝗虫的感病率分别为３７．５％、５５．０％和５２．５％。 |

| Abstract: | Field experiment on integrating application of Nosema locustae and insect growth regulator (Cascade R 1] ) to control the oriental migratory locust (Locusta migratoria manilensis) at high density was conducted in Tianjin Nlocustae and Cascade were applied by UVL in alternative stripes The dosage of Cascade (5%) used in the three plots was 150ml/ha, and the dosages of Nlocustae in the three plots were 15109,225109 and 30109 spores/ha respectively On the 7th day after treatment the locust populations were reduced 8965%, 7591% and 8976% respectively The infection rates of the survivors by Nlocustae were 375%, 550% and 525% respectively |
| Keywords: | Locusta migratoria manilensis Nosema locustae Cascade infection |
