Abstract

This exercise investigates the fruit fly’s preference for certain fruits. The fruit used to start the population of fruit flies can be modified to any fruit the student wishes. I normally recommend pineapple as the fruit to start the population of fruit flies as fruit flies seem to infest acid fruits more than non-acid fruits. All the fruits used in this experiment are available all year round in south Texas. This exercise was designed for majors and non-majors as well as for first-semester general biology students, who have had little experience in lab or in writing a lab report. This exercise prepares students to analyze a complex lab problem, write a formal lab report, interpret data, and make graphs.
