枣树锈壁虱属蛛形纲、蜱螨目,是当前危害枣树的严重害虫。六十年代初,我省乐陵、庆云、无棣、宁阳、巨野、邹县、滕县、茌平、寿光等主要枣产区均有发生;河北、河南、山西、甘肃等省枣区也有分布。由于该虫体极小,裸视不可见,往往不被人们发觉,再加八十年代以来,防治枣尺蠖由过去使用的有机磷等农药改为用菊酯类农药。
Jujube tick ticks arachnids, acarina, jujube is the current serious pests. In the early 1960s, major jujube producing areas such as Leling, Qingyun, Wudi, Ningyang, Juye, Zouxian, Tengxian, Chiping and Shouguang in our province all occurred. Hebei, Henan, Shanxi and Gansu provinces Jujube District is also distributed. Since the parasites are extremely small and the invisible eyes are not visible, people are often not aware of them. In addition, since the 1980s, pesticides such as organophosphorus pesticides used in the prevention and treatment of jujube were replaced by pyrethroid pesticides.
