| Abstract: | Imature stages of the Banana fruit caterpillar, Tiracola plagiata (Walker, 1857) and its close relative, Tiracola aureata Holloway, 1989 are described and illustrated. We revealed the following four facts. 1: The sixth instar is estimated to be the last instar larvae in both species based on the width of head capsules. 2: Morphologically they are distinguishable in the third to sixth instar larvae, but not distinguishable in the eggs, first to second instar larvae and pupae by our study. 3: Both species are polyphagous. 4: Some of the formerly known host plant records of T. plagiata should be excluded because they are revealed to be the hostplants of T. aureata. |
