1. Effects of Plant Age and Quality on Gratiana boliviana Performance on Tropical Soda Apple by Divina Amalin Jined Lamata Luis Bradshaw Amy Roda Catharine Mannion

2. OBJECTIVES to evaluate the feeding and reproductive performance of G. boliviana on different ages of TSA plant to determine the plant quality in different ages of TSA plant and its relation to G. boliviana performance

3. METHODOLOGY Plant ages (2, 3, 3+ month old) Leaf categories ( young, middle, old) Plant in bugdorm 10 adults (5 ♀ :5 ♂ ) 3 replications Data gathered (leaf consumption, # eggs laid, leaf nutrient)

7. METHODOLOGY………………continued Leaf consumption - Image-Pro MC® Insect fecundity – eggs counted Leaf nutritional analysis - Vario Max Elemental Analyzer

9. Category I before after

10. Category II before after

11. Category III before after

12. Feeding performance and reproductive performance of G. boliviana

13. Reproductive performance of G. boliviana

14. Plant age and leaf age category interaction on feeding performances and reproductive performance of G. boliviana Leaf Category IIII III AB

16. Result of nutrient leaf analysis a a abb

17. CONCLUSION G. boliviana preferred younger plants but more so younger leaves Nutrient level in different ages of TSA plant and age of the leaves seems to have an effect on the insect preference
