Report in brief from 2021/22:

  • The resistance in the field populations of Chilo suppressalis from Hubei and Anhui province increased significantly with the high resistance areas spreading further.
  • Some cases of control failure of Nilaparvata lugens were observed in the field which raises some concern
  • The 2021 Chinese version of the MOA Classification and IRM Guidelines for Sucking Pest were published and promoted
  • Broflanilide, the first launched product from MoA Group 30, was widely used for control of Phyllotreta striolata and Plutella xylostella, but as there is no other efficient products for rotation, resistance is expected to develop.
  • Ongoing SSB and FAW resistance monitoring programs were supported by multinational companies, domestic companies and NATESC.
