【Abstract】 The research bases on ultra-low volume aerial spray using pesticid of Nicotine+Matrinc and AV bacteriophage against Dendrolimus superans 28?700?hm~2 in A′ershan Forest Burea of (Daxing′anlin)g of Inner Mongolia in May～Julye, 2004. The result shows that the average montality of Dendrolimus superans are 91.64% , 89.53% and 92.39% on fifth day. The result also proves the pesticide of Nicotine+Matrinc and AV bacteriophage against Dendrolimus superans are effective, stable , rapid and long-lasting biotic pesticides .更多还原
