Abstract
The interactions of Holymenia clavigera (Herbst) and Anisoscelis foliacea marginella (Dallas) with their hosts (Passifloraceae) in southern Brazil are poorly understood. Previous studies have indicated that both species use several host species and plant parts and have superior performance on wild hosts. This study evaluated feeding preferences and host plant use under both laboratory and field conditions. Choice tests were performed to determine preference for Passiflora suberosa parts, preference for P. suberosa and Passiflora misera immature and ripe fruits, and preference for P. suberosa, P. misera, and Passiflora edulis shoots. A field survey was carried out to assess H. clavigera and A. foliacea marginella use of P. suberosa parts. In addition, immature and ripe fruits of P. suberosa and P. misera were characterized in relation to pH, phenols, and anthocyanins. First-instar nymphs preferred the terminal buds, shifting to immature fruits in the second instar. Both coreids more frequently fed on immature fruits than on ripe ones. Neither species showed a significant preference among host species. The immature fruits presented higher phenol content as compared with the ripe fruits; the opposite was observed for anthocyanins. In the field, immature fruits and mature leaves were selected for feeding and resting. Thus, this study confirms the food mixing condition of these coreids, as well as the importance of fruits for their nutrition. Phenols, and presumably water, in the fruits may play a role in their feeding choices.
