小檗碱的驱鸟活性试验

Study on the repellent activity of berberine on birds

为研究不同用量小檗碱对鸟类的驱避效果,开展了室内活性试验和田间药效试验。试验结果表明,小檗碱对鸟类具有显著的驱避效果,驱避机制为味觉驱避。在室内活性试验中,1 kg水稻种子用小檗碱0.5 g(有效成分用量)拌种处理,对白腰文鸟的拒食率为98.19%,对珠颈斑鸠的拒食率为89.13%。田间试验中,1 kg水稻种子用小檗碱0.5 g拌种处理,播后1 d的驱避率为85.6%,播后3 d的驱避率为83.9%。小檗碱对白腰文鸟、珠颈斑鸠等安全,具有开发成为新型绿色驱鸟剂活性成分的潜力。

In order to study the repellent activities of berberine on birds,the laboratory tests and field efficacy trials were carried out.The results showed that berberine had significant repellent effects on birds,and the repellent mechanism was taste repellent.In the laboratory experiment,when the rice seeds 1 kg treated with berberine 0.5 g(dosage of active ingredient),the refusal rate was 98.19%to Lonchura striata and 89.13%to Spilopelia chinensis.In the field experiment,when the rice seeds 1 kg treated with berberine 0.5 g,the repellent rate was 85.6%on the first day after sowing and 83.9%on the third day after sowing.Berberine was safe to birds,and had potential for development as a new active ingredient of bird repellent.
