Resumo: | We studied the effects of plant species on the development of Wollastoniella rotunda under laboratory conditions. We reared newly emerged first instars of W. rotunda on eggs of Ephestia kuehniella together with one of four different plant leaves, eggplant, cucumber, kidney bean and tomato. As a control, we used either moist cotton wool or nothing instead of the plant leaves. In the absence of water, first instars died within a day, suggesting that the predator needs to acquire water from plants in order to survive. Survival rates of W. rotunda differed among plant species, being lowest on cucumber leaves when compared to eggplant or tomato leaves. The duration of instar development was not affected by plant species. When offered moist cotton wool, bugs exhibited statistically similar survival rates compared to those offered any of the plant leaves; however, the development time of instars reared on eggs with water was longer than that on eggs with each plant leaf. These findings suggest that, by feeding on plants, the predator acquires both water and supplementary nutrients which reduce the development time.
