摘要
Antifeedant activity of extracts from Andrographis paniculata against the 1st and the 4th-instar larvae of the diamondback moth (DBM), Plutella xylostella, was tested by using leaf disc of cabbage. Furthermore, the antioviposition effect was also observed on the caged cabbage plant treated with the fractions. The active fractions from the acetone extract suppressed feeding by the 1st and 4th-instar larvae at the concentrations of 60 ppm and 500 ppm, respectively. The antioviposition activity against DBM females was also found at the concentration of 125 ppm.
