Abstract

The wheat brown mite is relatively coarse and visible to the naked eye, and its body color is black, brown or yellow. The hair on the back surface of this species is not on the gland, the hair is short and the tip of the hair does not reach the base of the hair. It has 4 pairs of legs, the length of the first legs is much taller than the body length and three pairs of other legs. Damage to wheat fields is mainly due to the tillering stage and before stemming. The brown wheat mite at these stages, feeding wheat leaves, weakens the plant and reduces the number of tillers. The eggs laid down in the late spring are summer dipped eggs and spend their entire summer season as eggs. The leaves of infected wheat bushes feed on the mite, starting from the end to the base, turn yellow, brown and tan and dry. In addition to the leaves, the planting and feeding of spikes can cause pale spots. At the time of attack, the pest is from late March to mid May
