✦ Synopsis

The effect of sexual tliff ci-cnces in tlctermining nutritional requirements is well demonstrated by mosquitoes and horseflies. Both males and fcmaIes of thcse species feed on nectar and sweet sap ; in addition, the females ingest blood to satisfy the protein demands of egg production. That a similar dietary supplement is needed by the female house fly was shown by Glaser ( '23) in a qualitative and indirect, way. Hc presented various combinations of sugar and protein to a small number of males and females and observed good egg production only when both classes of food .\rcre available. Galun and Fraenlrel ( ' 3 7 ) measured the average daily consumption of it 5% sucrose solution by equal numbers of males and females kept in a pint jar. This paper reports the consumption of protein and sugar by each sex kept separately under conditions which diff e r in as least three respects from their experimental procedure: (1) the testing period is considerably longer; (2) the flies are less crowded; ( 3 ) thc females' ovipositional need is satisfied.
