本研究探讨了田间小菜蛾种群ryanodine受体突变（G4946E和I4790K）比例的变化。结果表明，G4946E的比例下降，在调查期间，没有联酰胺的应用程序和昆虫与I4790K的观察不太频繁。本研究还研究了抗二酰胺小菜蛾菌株的生物学性能。结果表明，抗性品系的孵化率、幼虫发育和繁殖力与敏感品系相当。
This study examined changes in the proportions of ryanodine receptor mutations (G4946E and I4790K) for Plutella xylostella populations in the field. Results show that the proportion of G4946E decreased during the survey years without diamide application and that insects with I4790K were observed less frequently during the survey period. This study also examined the biotic performances of diamide-resistant P. xylostella strains. The results show that the diamide-resistant strains exhibited hatchability, larval development, and fecundity equivalent to those of diamide-susceptible strains.
