Insecticidal activity of transgenic rice. (A) Tissue damage caused by SSB (Aa) and YSB (Ab) feeding. The stem cuttings of control (upper) and transgenic (K13) (lower) plants were infested with neonate SSB or YSB larvae and pictured 5 days after infestation. (×5.) (B) SSB (Ba) and YSB (Bb) larval development in nontransgenic (upper) and transgenic (K13) (lower) plants. SSB and YSB larvae were allowed to feed on stem cuttings of nontransgenic and transgenic plants and were photographed 1–4 days after infestation. (×10.)
