Cry2A rice did not affect the interspecific interactions between two rice planthoppers, , and .

Interspecific interactions are complex in agro-ecosystems and could be affected by agricultural technologies including transgenic crop planting. Few studies focused on the effects of Bt crops on the interspecific interactions of non-target organisms. Here we assessed the effects of transgenic rice (Cry2A rice) on the interspecific interaction between two rice planthoppers, namely, (the brown planthopper, BPH) and (the white-backed planthopper, WBPH).
