NO. 14 SENSE ORGANS ON MOUTH-PARTS OF BEE — McINDOO

two counts, 37 per cent were seen eating the honey and 4 per cent 

 the syrup, making - a total average of 41 per cent eating at any one 

 count. 



In the same manner light-colored honey and pollen mixed thor- 

 oughly with light-colored honey (1 part pollen to 4 parts honey) were 

 given to fresh bees. As an average for the ioo.bees for three counts, 

 26.3 per cent were seen eating the light-colored honey and 16.3 per 

 cent the honey mixed with pollen, making a total average of 42.6 per 

 cent eating at any one time. 



In the same way light-colored honey, and sugar mixed with light- 

 colored honey (half and half) were fed to bees. As an average for 

 the 100 bees for five counts, 30.4 per cent were seen eating the honey 

 and 11 per cent the mixture of sugar and honey, making a total 

 average of 41.4 per cent eating at any one count. Since one of these 

 foods was a thick paste, five counts were recorded before the bees 

 ceased eating, while in the experiments just preceding only three 

 counts were necessary, because the mixture of pollen and honey made 

 a thin paste. 



The following is a tabulated summary of the preceding results 

 obtained by feeding bees sweet foods. The figures in the third to 

 fourteenth columns represent the average per cent or number of bees 

 eating a particular food at any one time.

 Experiments in Feeding Bees Sweet Foods 



It is evident from the above table that bees show preferences 

 between sweet foods.
