| Abstract: | The insecticidal activity of extracts from Eupatorium adenophorum Spreng against the adults of the rice weevil Sitophilus oryzae (L.),maize weevil S.zeamais Motschulsky,Chinese bean weevil Callosobruchus chinensis (L.),and European bean weevil Bruchus rufimanus Boheman was studied.The results showed that the mortality of the four species reached 100 00% when treated with the fumigant concentration of 44.44mg/L.The further bioassay revealed that the LC 50 after treating the four species for 24h were 14 65,12 80,25 07 and 12 20mg/L respectively,and the LC 50 after treatment for 48h were 11.79,9.67,13.29 and 9.76mg/L respectively. |
