摘要
茶小绿叶蝉抗药性研究进展缓慢。本研究通过前期建立的抗药性快速检测方法,以荒废茶园(福安王家茶场)小绿叶蝉为相对敏感品系,测定了福建福安、安溪和武夷山3个不同地区茶小绿叶蝉对5种常用农药的抗药性程度。试验结果表明,3个地区茶小绿叶蝉对联苯菊酯的相对抗性倍数分别为12.70、16.81和15.72倍;溴氰菊酯的相对抗性倍数分别为9.28、11.20和8.89倍;高效氯氟氰菊酯的相对抗性倍数分别为4.72、7.69和10.13;溴虫腈的相对抗性倍数分别为1.30、3.44和5.56倍;唑虫酰胺的相对抗性倍数分别为1.69、3.27和3.45倍。该研究结果表明了在福建不同地区的茶小绿叶蝉对菊酯类农药抗性较为明显,对溴虫腈和茶园新农药唑虫酰胺也产生了较小的抗性,同时对前期建立的抗药性检测方法做了进一步进验证,方法简便且可行。
Empoasca flavescens(Homoptera:cicadellidae)is a pest insect difficult to be captured in the wild or bred indoors for insecticide resistance studies.This experiment managed to collect tea jassids from the abandoned Wangjia Tea Farm in Fuan to compare with those caught at other tea growing areas in the province on their sensitivities toward 5 commonly applied pesticides.The drug resistance of the insects was determined by using a previously established rapid detection method to show that the E.flavescens from Fuan,Anxi,and Wuyi on(A)bifenthrin to be 12.70,16.81,and 15.72,respectively,(B)on deltamethrin 9.28,11.20,and 8.89,respectively,(C)on lambda-cyhalothrin 4.72,7.69,and 10.13,respectively,(D)on chlorfenapyr 1.30,3.44,and 5.56,respectively,and(E)on tolfenpyrad 1.69,3.27,and 3.45,respectively.The tea jassids appeared to have developed a significant resistance to pyrethroid-class insecticides in the regions and somewhat milder resistance to chlorfenapyr and tolfenpyrad.The detection method employed in this study was simple and adequate for the purpose.
