The acaricidal mechanism of Stellera Chamaejasme extracts against Tetranychus vienneusis
Previous reports showed that the root extracts of Stellera Chamaejasme L had acaricidal activity against Tetranychus vienneusis Zacher. However, the acaricidal mechanism of the root extracts from Stellera Chamaejasme L against Tetranychus vienneusisis not clear. Here, the effects of the root extracts from Stellera Chamaejasme L. on the activities of three enzymes of mites: protease, glutathiona s-transferase (GSTs) and esterase isozyme, were detailedly studied. Our results showed that the activities of protease, GSTs and esterase isozyme in treated mites were induced by the root extracts from S. chamaejasme in the systemic toxicity bioassay compare with those of the control. The effects of the root extracts from S. chamaejasme on the activities of some important metabolism enzymes of T. vienneusis may help to elucidate the acaricidal mechanism of the root extracts from Stellera Chamaejasme L against Tetranychus vienneusis.
