The effect of food source on survival and development of Lilioceris cheni (Coleoptera: Chrysomelidae), a biological control agent of air potato (Dioscoreales: Dioscoreaceae)
Florida Entomologist 99 (1), 154-155
Abstract: This study demonstrated that early instars of Lilioceris cheni Gressitt and Kimoto (Coleoptera: Chrysomelidae) larvae survived on air potato (Dioscorea bulbifera L.; Dioscoreales: Dioscoreaceae) leaves, whereas older larvae successfully developed on leaves and bulbils. However, leaves provided a superior diet to bulbils for older larvae based on a shorter development time. Survival from 3rd instar to adult was not different on leaves and brown bulbils, but for unknown reasons, survival was very poor on tan bulbils.
