*Non-transgenic, near-isoline cultivar used as a control.

**Age/size of insects counted. L = larvae, size unspecified; LA = all larvae (neonate to largest instar); LL = large larvae only; I = immatures (larvae, nymphs, pupae); N = nymphs; A = adults

†N = naturally infested, A = artificially infested

‡Values estimated from figure.
