摘　　要：以松香为原料经Diels-Alder加成反应合成了松香多元酸如丙烯海松酸(APA)、富马海松酸(FPA)及马来海松酸(MPA)。采用浸叶法,研究了松香多元酸以及脱氢枞酸对小地老虎(Agrotis ypsilon)的拒食活性。结果显示:质量浓度为1 g/L时,脱氢枞酸、丙烯海松酸、马来海松酸和富马海松酸对4龄小地老虎幼虫的24 h拒食率分别为0. 68%、78. 41%、13. 41%和79. 94%,其中丙烯海松酸及富马海松酸对小地老虎的拒食活性较高,而马来海松酸对小地老虎的拒食活性较弱,脱氢枞酸几乎没有拒食活性。丙烯海松酸及富马海松酸对小地老虎的拒食中质量浓度(AFC50)分别为0. 04和0. 06 g/L,可以进行田间试验,进一步明确其在生产中的实际防治效果。Polyacid derivatives of rosin such as acrylpimaric acid(APA),fumaropimaric acid(FPA)and maleopimaric acid(MPA)were synthesized by Diels-Alder addition reaction from rosin.The antifeedant activities of polyacid derivatives of rosin and dehydroabietic acid against Agrotis ypsilon were investigated by leaf disc method.The results showed that antifeedant rates of dehydroabietic acid,acrylpimaric acid,maleopimaric acid and fumaropimaric acid against Agrotis ypsilon reached 0.68%,78.41%,13.41%and 79.94%at 1 g/L after 24 hours,respectively.Acrylpimaric acid and fumaropimaric acid had good antifeedant activities against Agrotis ypsilon,while maleopimaric acid exhibited weak antifeedant activities against Agrotis ypsilon and dehydroabietic acid almost didn t have antifeedant activity.The 50%antifeedant mass concentrations(AFC 50)for acrylpimaric acid and fumaropimaric acid were 0.04 and 0.06 g/L,respectively.Field experiment could be carried out to further detect its actual control effect in production.
