Spider mite (Tetranichus urticae) is a dangerous, small and polyphagous pest. The mite is active as a rule on the undersides of leaves braiding them with a web. They suck out plant sap causing the deformation and the decolorization of injured leaves. The leaves assume a marble tint, become dark-brown and wither. The pest gives 8-10 genarations during the period of vegetation. They hibernate in plant residues and weeds.
