K. Matsuda et al., SOYASAPONINS AS FEEDING STIMULANTS TO THE ORIENTAL CLOUDED YELLOW LARVA, COLIAS-ERATE-POLIOGRAPHUS (LEPIDOPTERA, PIERIDAE), Applied Entomology and Zoology, 33(2), 1998, pp. 255-258
Feeding stimulation of soyasaponins on oriental clouded yellow larva,
Colias erate poliographus, which feeds on Leguminosae, was investigate
d. Soyasaponin Bb showed strong feeding stimulation, and Ba and Be exh
ibited moderate activity. HPLC analysis of soyasaponins revealed that
the content of soyaspaonin Bb was considerably higher than those of Ba
and Be. These results indicated that soyasaponin Bb acts mainly as a
feeding stimulant in the host selection of soybean by oriental clouded
yellow larvae. The role of soyasaponins in the host selection of orie
ntal clouded yellow larva is discussed.
