Insect bioassays using leaf tissues of l20 day old control and transgenic lines of cotton.

<p>Four day old insect larvae were released on the leaf tissues and pictures were taken after 3 days of feeding. (A) Consumed surface area in (a) the control plant (b) BioCot-1 (event Mon 531 in a hemizygous condition) (c) BioCot-2 (event Mon 531 in a homozygous condition) (d) eventTM-2 (e) eventTg2E-13 and (f) F1 (TM-2 x Tg2E-13); (B). Percent mortality of larvae fed on leaf tissues of different transgenic lines.
