主 题：diamide insecticides resistance resistance risk Spodoptera frugiperda
摘 要：Spodoptera frugiperda(Lepidoptera:Noctuidae)is a widely distributed pest of *** it invaded China in 2018,it has caused serious damage to local corn ***,an anthranilic diamide insecticide,has been widely used to control lepidopteran *** is a new allosteric modulator insecticide devel-oped based on chlorantraniliprole,so it has a similar mechanism and insecticidal *** this study,we investigated resistance levels to chlorantraniliprole and tetrachloropyramid in *** from 13 populations in *** the populations tested,the relative highest resistance to chlorantraniliprole occurred in the Guangzhou population,and the most susceptible to chlorantraniliprole was found in the Wuhan *** lethal dosage LD50 value of the Guangzhou population against chlorantraniliprole was 27.8-fold higher than that of the Wuhan *** differences were observed among 5.frugiperda populations in terms of sensitivity to *** mutations at the 14734 site of the ryanodine receptor(RyR)were found,while no mutations were found in the G4891 *** mutations were detected in only two of the 786 individuals analyzed one from the Qinzhou population and other from the Anshun population(frequency below 2%in both cases).There were no significant differences in the expression levels of RyR between Guangzhou and Wuhan *** summary,our results indicate that:(i)*** has low resistance levels to diamide insecticides in China;and(ii)the differences in relative resistance among the 13 populations analyzed are not caused by the mutations in RyR or the expression of RyR.
