| 摘 要： | The most provocative aspect of this study is its original findings on the toxicity of diphenyl-pentenone (1,5-diphenyl-2-penten-l-one, DP) against the three kinds of aphids (Maerosiphum granarium Kirby, Lipaphis erysimi (kaltenbaeh), Schizaphis aurantiae (Fosc.) and the inhibitory effects of DP againstdetoxification enzyme system of the aphid (S aurantiae). The result of bioassay in the laboratory shows that the product has strong contact activity and very good antifeeding activity, with higher efficacy than anabasine and nicotine, two botanical aphidicides. The median lethal concentrations of the three products against the apterous adult (Mgranarium) are 175.85, 217.23 and 245.22 mg/L, respectively, at 24h of pest treatment. DP is inferior to methomyl in contact assay but superior in antifeeding activity assay against the three aphides. DP has strong inhibitory effects on nonspecific esterases, carboxylesterase of aphid (S aurantiae), but it can not inhibit AchE. DP also has strong inhibitory effects on glutathione Stransferase of the aphid.

| Abstract: | The most provocative aspect of this study is its original findings on the toxicity of diphenyl pentenone(1,5 diphenyl 2 penten 1 one, DP) against the three kinds of aphids ( Macrosiphum granarium Kirby, Lipaphis erysimi(kaltenbach), Schizaphis aurantiae(Fosc. )and the inhibitory effects of DP against detoxification enzyme system of the aphid ( S aurantiae ). The result of bioassay in the laboratory shows that the product has strong contact activity and very good antifeeding activity, with higher efficacy than anabasine and nicotine, two botanical aphidicides. The median lethal concentrations of the three products against the apterous adult ( M granarium ) are 175.85, 217.23 and 245.22 mg/L, respectively, at 24 h of pest treatment. DP is inferior to methomyl in contact assay but superior in antifeeding activity assay against the three aphides. DP has strong inhibitory effects on nonspecific esterases, carboxylesterase of aphid ( S aurantiae ), but it can not inhibit AchE. DP also has strong inhibitory effects on glutathione S transferase of the aphid. |
