H. Yasui et M. Yazawa, FEEDING RESPONSE OF THE SILKWORM, BOMBYX-MORI, TO COMPOUNDS INDUCED BY UV IRRADIATION OF MULBERRY LEAVES, Bioscience, biotechnology, and biochemistry, 59(7), 1995, pp. 1326-1327
Irradiation of mulberry leaves with UV reduced the feeding response of
Bombyx mori silkworm larvae. An organic extract of UV-irradiated leav
es was fractionated and, in the acidic fraction which showed antifeeda
nt activity, moracins C and N, known as phytoalexins, were identified.
These compounds were induced by UV irradiation and affected the insec
t's food consumption by acting as feeding deterrents.
