| Abstract: | This paper presented the investigation result of tile applicatioll of industrial test preparation of Beauveria bassiana against the Asian Corn Borer,(ACB),Ostrinia furnacalis,in the corn stalk piles in the area of 1000 ha corn of Town Suburn of Dongfeng County. Not only did the application diminish the overwintered larva density in Spring,but prevented the field corn plants from damage of ACB. Such a large-scale application of industrial test product showed that it call reduce the percentageltage of damaged.corn plants borered holes on corn plant and remaining mature-aged arvas in Autumn by 67. 24%,77. 61 % and 83. 17%,respectively. |
