| The repellent effect of the alcohol extracts of 25 tropical plants to Oligonychus biharensis Hirst was studied in laboratory.The results showed that a majority of extracts that were tested had significant repellent effect on the adults and oviposition of O.biharensis.The repellent effect of twenty extracts on the adult surpassed 80% after 24h,and the repellent effect of Helicteres angustifolia L.was 97.78%,the highest among the extracts tested.The repellent effect of twenty-three extracts on oviposition of O.biharensis surpassed 80%,whereas that of the extracts from Melodinus suaveolens Champ.ex Benth,Pterospermum heterophyllum Hance,H.angustifolia and Datura metel L.was 100%. |
