Studies on the Feeding Habits of the Brown Planthopper, Nilaparvata lugens (STAL) : Hemiptera : Delphacidae : V. Probing Stimulatory Effect of Rice Flavonoid

Abstract

The probing stimulatory effect for feeding of N. lugens was found in the cases of four kinds of rice flavonoids, tricin-5-glucoside, glucotricin, orizatin and homoinetin; and out of the other 13 flavonoids, luteorin showed the effect as strong as that of the rice flavonoids.
