Fluctuation of Doleschallia bisaltide larvae (Lepidoptera: Nymphalidae) on caricature-plant (Graptophyllum pictum).Caricature-plant cultivation is often damaged due to the attack of Doleschallia bisaltide larvae. High reproduction ability ofD. bisaltide is a serious problem that need to be managed, therefore it will not inflict a financial losses. This study was aimedto determine the fluctuation of D. bisaltide larval population in the caricature-plant plantation in Kalisoro, Tawangmangu.The observations were carried out with a survey method on five observation plots for seven months from March to September2018. The data were analyzed by descriptive statistics and the Spearman rank correlation coefficient test. The results showedthat the population structure was changed during the observations with the highest larval population in May. The results ofSpearman rank correlation coefficient test showed significant and positive correlation between third, fourth, and fifth instarslarvae with the rainfall. The control of D. bisaltide can not only depend on the presence of natural enemies, therefore controlinterventions were needed especially at a suitable time and environment whne the population increased.
