1 Objectives Research Problem 1: Animal growth and metabolism Bio 31 - Spring, Conduct a hypothesis-driven investigation of patterns and/or processes in the growth of insect herbivores. 2. Write a research paper, in the form of a contribution to the primary literature, describing the study. 3. Learn the methods and analyses that are fundamental to studies of animal growth, consumption, assimilation, and metabolism. Specifically, the:.! Principles, measurement, calculation, and interpretation of relative growth rates (Appendix 1);! Principles, calculation and interpretation of consumption rate, assimilation rate, apparent digestibility, and conversion efficiencies (Appendix 1);! Principles, measurement, calculation, and interpretation of respiration rate using an infrared gas analyzer (IRGA) and respiration accessory (RACC) (Appendices 2-4); Materials! Larvae of four species of insect herbivore (Table 1).! Potted plants of numerous plant species grown under an assortment of environmental conditions (Table 2).! Artificial diet appropriate for all the insects in Table 1.! Vials suitable for insect growth trials with detached leaves.! An electrobalance (± 0.1/ 0.01 mg)! An infrared gas analyzer that measures CO 2 concentrations in parts per million (ppm)! A respiration accessory (RACC) and gas-tight syringes that allow measurement of CO 2 concentrations in respiration flasks.! Respiration flasks of different sizes.! Mesh bags suitable for limiting the locomotion of animals within respiration flasks.! Environmental chambers set at constant temperatures of 12, 18, 24, and 30 C (all with photoperiod of 12:12 light:dark.) Table 1.

Each species was grown in a factorial combination of normal and low nutrients (N, P, and K) crossed with cool or warm temperatures. Plants in all treatments have been watered sufficiently to avoid moisture stress. Entries indicate number of replicates. Cool (20 day, 15 night C) Warm (25-30 day, 20 night C) Plant species Normal N,P,K Low N,P,K Normal N,P,K Low N,P,K Lycopersicon esculentum (tomato) Nicotiana alata (tobacco) Glycine max (soybean) Helianthus annuis (sunflower) Zea mays (corn) Hordeum vulgare (barley) day: night photoperiod, 12:12 > 14: 10 hrs transition over 4 weeks cool in incubator / warm in greenhouse
