A novel negative thermotaxis behavior in rice planthoppers is regulated by TRPA1 channel.

We reported a novel cold preference (negative thermotaxis) in rice planthoppers that was regulated in WBPHs by the TRPA1 channel. Cold preference of rice planthoppers is probably related to its choice behavior of the special migratory temperature layer. Our results expanded a new perspective to develop novel strategies for behavioral manipulation and management of rice planthoppers. © 2020 Society of Chemical Industry.
