| Abstract: | In order to grasp the toxicity and action mode of the active substance in Euphorbia helioscopia,the author took the whole plant of Euphorbia helioscopia as the experimental material,used different solvents to extract the active substance,and then carried out the laboratory tests of contact,stomach and repellent toxicity to cabbage aphid.The results showed that the ethyl acetate extract from Euphorbia helioscopia had higher contact toxicity,the regressive equation of the toxicity was y=2.663x-4.529,and its L... |
