Fig. 5. Spodoptera frugiperda moths prefer to oviposit on uninfested Zea mays plants. To test the effect of prior infestation with S. frugiperda (FAW) compared to a non-treated (NT) control plant on S. frugiperda oviposition preference, a pair-wise oviposition assay was performed using 3 independent experiments (Experiments 1–3). In each experiment, 6 uninfested plants and 6 infested plant treatments were used, and egg masses on each plant counted (Table). The total number of egg masses on each treatment was determined and from these data the percent total oviposition (%NT and %infested plant) calculated. The graph shows the mean (± SE) percent parasitism for each treatment,and the treatments were statistically significantly different using a pair-wise t-test: P ≤ 0.05; n = 3.
