Daily intake of sucrose and brain-heart extract by a virgin female blowfly when the protein was paired with .17 sucrose and when it was paired with M sucrose. Number and duration of visits in a two-choice situation In order to assist in correlating the behavior of flies taking single drinks with the measurements of total daily intake, records were made of the number and dura- tion of visits made by flies in the two-choice situation. The records showed that females which had been denied protein made approximate!}- equal numbers of visits to each of the two pipettes but that they took only small nips of the carbohydrate and long draughts of the protein. Males and females which had had free access to protein also made equal visits to both pipettes but took very few drinks of protein. Drinks of sugar were more hearty. Anosmic flies Since all of the protein solutions employed possessed distinct odors, an attempt was made to assess the role of odor by measuring intake and observing the reactions of flies that had been rendered anosmic by removal of the antennae, labellum, and labial palpi. Anosmic flies were tested in all of the situations already described. In no case did their behavior differ from that of the normal flies. Contact clicniorcceptors It was clear from observing the behavior of flies in the ring tests that they were able to differentiate between protein and sucrose by means of the tarsi and the.
