The yellow boards play an important role in prevention and cure white fly in greenhouse because they can trap, stick and kill white fly. The test also shows that almost white fly often appear in the space where 5cm-15cm upper than the top of the plant. According to this result, the optimal hanging height of the yellow board should be at the place where 5cm-15cm upper than the top of the plant. The yellow boards should be set up as much as possible in this space to reach the best preventative effect.
