利用生物毒素来抑制有害昆虫的生长一直是植保科研的一个重要课题 日前日本大孤生物工程 研究所研制出一种生物型农药并开始小批量投入实际应用 据了解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几万倍稀释后制成的农药液剂喷施后可杀灭多种农作物害虫和林木害
The use of biological toxins to inhibit the growth of harmful insects has been an important issue of plant protection research Recently Japan’s Institute of Bioengineering bio-engineering developed a bio-pesticide and start small batch of practical application It is understood that the first batch of bio-pesticides from Vespians Of the poisonous gland extract of the wasp toxin after tens of thousands of times diluted pesticide solution can kill a variety of crop pest and tree damage after spraying
