Isovitexin-2'- O -β-[6- O -E- p - coumaroylglucopyranoside] from UV-B irradiated Leaves of Rice, Oryza sativa L. inhibits Fertility of Helicoverpa armigera

Cassi-Lit, Merdelyn T.; Tanner, Gregory J; Nayudu, Murali; Whitecross, Malcolm

Description

UV-B irradiated rice leaves (Oryza sativa L.) contained four closely related flavonoids, with either an isoorientin or isovitexin aglycone. These flavonoids have previously been purified and characterized, and were added to artificial diets of the African bollworm (Helicoverpa armigera Hübner) at 0.1x concentration found in irradiated rice leaves. Consumption of different diets had relatively small effects on laval, pupal and adult duration, weight and survival, indicating the insects lived...[Show more]
