Abstract: 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 1g/L after 24hours, 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(AFC50) for acrylpimaric acid and fumaropimaric acid were 0.04 and 0.06g/L, respectively. Field experiment could be carried out to further detect its actual control effect in production.

Key words: polyacid derivatives of rosin, Agrotis ypsilon, antifeedant, 50% antifeedant concentration
