Instructions for AP BIOLOGY Investigation 12-Fruit Fly Behavior *We will be using Roly-polies (Armadillidium vulgare) to study animal behavior instead of fruit flies. They are members of a family of woodlice in the order Isopoda that are able to roll into a ball. When writing up this lab, substitute A. vulgare or “roly-poly” or “pillbug” for Drosophila melanogaster throughout. **You still have to know the basics of fruit fly behavior, so be sure to read the lab carefully and save the lab handout to study later for the AP Exam. ***The Pre-lab (due before we start the lab) includes PART I- PART IV. I. Title:
Leave this blank until after completing the pre-lab questions (below). II. Objectives: – Read and copy the “Learning Objectives” on page S146. III. Pre-lab Questions: (You will need to look this information up! Use your textbook and Google/Blackle!) Define ethology and differentiate learned and innate behavior. Compare/contrast taxis and kinesis. Give some examples. (Use your own words.) Research a pill bug behavior. What type of environment do they prefer? Are the nocturnal or diurnal? What do they eat? Where would you go to find roly-polies? IV. Methods:
Read the procedures (“Getting Started” pp. S147-S148, “Procedure” pp. S148-149, and “Designing and Conducting Your Investigation” p. S150) in the lab handout carefully so that you know what you will be doing when you come to the laboratory. Answer the following questions: 1. What is chemotaxis?
2. What is geotaxis?
3. What is a choice chamber?
4. What substances do you think would result in a positive or negative chemotactic response in roly-polies? 5. What environmental conditions do you think would result in positive or negative taxis in roly-polies? V. Data: You will conduct two experiments on the behavior of roly-polies. The second experiment will be one that you design with your lab group. For each experiment, you will: 1. State the hypothesis. You may use...
