Spodoptera frugiperdas that strike China have high resistance to traditional pesticides

In Oct. 2019, Centre of Ecological Genomics, Agricultural Genomics Institute at Shenzhen, Chinese Academy of Agricultural Sciences together with the team of academician Wu Kongming, Institute of Plant Protection, Chinese Academy of Agricultural Sciences and other institutes jointly released high-quality genome sequence of spodoptera frugiperda to expose biological genetic background and drug resistance features of spodoptera frugiperda groups that strike China based on genome for the first time, and to provide guiding significance for scientific control on spodoptera frugiperda. The research achievement was published online on BioRxiv.

 

Spodoptera frugiperdas that strike China have high resistance to organophosphorus pesticide.

 

The research team performed resequencing on 105 samples of spodoptera frugiperdas that strike 16 provinces (cities or autonomous regions) in China, and exposed that spodoptera frugiperdas that strike China are hybrid spodoptera frugiperdas with maize genetic background. It is found through scanning detection of resistance-related genes that the groups that strike China have relatively high frequency of resistance genetic variation towards traditional organophosphorus pesticide, organochlorine pesticide and pyrethroid pesticide, while the team did not find any mutation site of resistance gene towards new amide pesticide and Bt toxin, showing that they have high resistance to traditional pesticide. Biological test result also proved that spodoptera frugiperdas have high resistance to organophosphorus and pyrethroid pesticide, but are sensitive to new amide pesticide and Bt toxin.

 

The research shows that it is not suitable to use such traditional pesticides as organophosphorus pesticide, organochlorine pesticide and pyrethroid to control the invasion of spodoptera frugiperda in China, while amide pesticide, Bt toxin and Bt crop can prevent spodoptera frugiperda effectively.
