Abstract: Botanical Acaricides are a hot spot in the research of pesticide at present. The screening of acaricidal plant is one of the main factors, and it has practical and academic importance. Acaricidal plant included medicinal plants, non-medicine natural plants. The significant differences in the acaricidal activity on the different plant species were not surprising since the plants come from different families. However, It was found that effect and acaricidal route of action also vary. It is possible that the observed differences could be due to the special physiology of acarid. At the same time ,this particularity also increase the wokload and difficulty of screening of acaricidal plants. The progress in research and development of the screening of botannical acaricide, including acting pathways and action mechanism of the acaricidal plants against mites have been introduced. New research field of botanical acaricides are discussed, alomg with the prospects of botanical acaicides.
