| Abstract: | The contact activity and repellent effect of the alcohol extracts of 31 tropical plants against Tetranychus cinnabarinus was studied.The results showed that the extract of Helicteres lanceolata DC.,Leucas aspera Link,Hunteria zeylanica Gard.Ex Thw.and Clerodendrum inerme Gaertn.had obvious contact activity to adult T.cinnabarinus.The average corrected mortalities rates were all above 80% after 24 hours,and the extract of Helicteres lanceolata DC.had the highest contact activity among the extracts tested,wit... |
