利用生物毒素来抑制农业有害昆虫的生长一直是植保科研的一个重要课题。现在，日本大阪生物工程研究所研制的生物型农药已开始小批量投入实际应用。首批生物型农药是从大胡蜂的毒腺中提取的大胡蜂毒素经过数万倍稀释后制成液剂农药的，它经过喷雾后杀灭多种农业、林业害虫，但
The use of biological toxins to inhibit the growth of agricultural harmful insects has always been an important issue of plant protection research. Now, bio-pesticides developed by Osaka Institute of Biological Engineering in Japan have started to put into practical application in small batches. The first batch of biopesticides was obtained after diluting tens of thousands of wasp toxins from the venom glands of the wasps to produce liquid pesticides. It sprayed to kill a variety of agricultural and forestry pests but
