There were few reports mentioned changes of protective enzyme activities of Tetranychus viennensis after exposed to pesticides by now. Our previous study had showed that the chloroform extracts of Kochia scoparia had effective acaricidal activity against T. viennensis. Here, the toxicosis symptoms of T. viennensis were detaiedly studied after exposed to the chloroform extracts of K. scoparia KFCE-2...
The acaricidal activities of root extracts from the of Tateges erecta against T. viennensis were determined under illumination and non-illumination conditions. Furthermore, the effects of chloroform extract on several enzymes activities of T. viennensis were also evaluated. According to the F-test statistical analysis, the chloroform extract had acaricidal activities against T. viennensis under non-illumination...
Few studies mentioned acaricidal activity of Wikstroemia chamedaphne against Tetranychus viennensis. Here, we reported that W. chamedaphne had strongly acaricidal activity against T. viennensis. A method for purification of miticidal components from W. chamedaphne was developed as follows: Step 1, methanol immersion at room temperature; Step 2, liquid-liquid partition using petroleum ether; Step 3,...
The extract of the K. scoparia had the acardial activity against the T. viennensis. Here the female adult mites were treated by the KFCE-2 extract of K. scoparia, the effective ingredient of the extract of K. scoparia. The toxicosis symptoms of T. viennensis in response to the the KFCE-2 extract of K. scoparia were observed. After treatment, the mites went through four phases: the motionless phase...
