In Experiments by Greene and Colleagues (1987)with the Tephritid Fly

Essay

In experiments by Greene and colleagues (1987)with the tephritid fly Zonosemata vittigera and the jumping spider Phidippus apacheanus,carefully controlled experiments were used to better understand the predator/prey relationship.Treatments were designed to test whether the display of the fly when disturbed served to mimic the appearance of the jumping spider and deter an attack.When the fly is exposed to the jumping spider,it holds its wings perpendicular to its body and waves them up and down,and additionally the flies have dark banding patterns on the wings.Explain the purpose of the five different treatments used in the experiment: Zonosemata untreated,Zonosemata with own wings cut and reglued,Zonosemata with housefly wings,housefly with Zonosemata wings,and housefly untreated.
