Ovipositional preference of fall armyworm females for maize plants subject to present herbivory (= exposed to conspecific larvae) or plants not subject to present herbivory (= plants not exposed to larvae) on two maize inbred lines, B73 and B73-<i>lox10</i>.

<p>Preference was assessed in a choice-test over a 24-h period, independently on each maize inbred line, and was measured as the numbers of eggs (filled circles) and egg masses (empty circles) laid by females on seedlings with (= Treatment) or without (= Control) feeding injury. Feeding injury was produced by confining three larvae on a seedling for 3 h, beginning 7–8 h prior to a trial. Overall, differences in eggs and egg masses laid per seedling were detected between seedlings with or without present herbivory <b>(A)</b>, and between B73 and B73-<i>lox10</i> maize inbred lines <b>(B)</b>, while a significant interaction between herbivory and maize inbred line was not found (F_{1, 84} ≤ 0.84, P ≥ 0.36).
