After the wheat is greened, the food intake of the pest increases and the damage is aggravated, which is easy to cause the lack of seedlings and ridges, which is a key period for pesticide control. In the Laizhou area, the temperature began to rise at the end of March, and the wheat was in the early stage of re-greening. Since then, the larvae began to increase the food intake and entered the peak period, which is the best period for prevention and control.
