Abstract

Abstract One of constrain in cultivation of caricature plant (Graptophyllum pictum) is insect pest attack namely Doleschallia spp. (Lepidoptera: Nymphalidae). Experiments with the objectives to determine the distribution of this butterflies and the degree of damage were carried out in three provinces, West Java, Molluca and Papua.

Results showed that there are two specieses of Doleschalliia attack caricature plant in Indonesia. The degree of infestation in West Java, Molluca and Papua was 17.8%, 28.0% and 1.9%, respectively. While the percentage of plants infested in West Java, Molluca and Papua was 53.4%, 56.9%, and 3.7% respectively. Duration of Doleschallia bisaltide eggs was 3.7 ± 0.9 days. The larvae passed five instars, with the larval development period of 19.7 ± 1.1 days. The duration of pupae was 9.9±0.3 days D. bisaltide could be multiplied by releasing approximately 50 adults in greenhouse. One female adult could lay 29 eggs in average.
