Red spider mites harm mulberry leaf, mainly mulberry beginning spider mites and cinnabarinus two kinds of harm in the province of Mulberry; spider mite reproduction environment suitable Mulberry, Mulberry is located in hilly areas, is mixed mulberry four weeks Grass grows, usually neither removes nor disinfects the surrounding weeds.
