FLIES DISLIKE YELLOW.
JAM FACTORY DISCOVERY. What makes flies avoid yellow glass ? That is the riddle thatjs perplexing a jam factory in Northern England. Yellgw glass was put in a warehouse to stop the jam from fading, and it was found .that dies completely avoided the yellow room. A partial explanation was supplied by Dr S. A. Neave, honorary secretary of the Entomological Society of London. “ Probably/’ he told a London Daily Chronicle reporter, “ the flies avoid the yellow glass room because yellow absorbs from the light certain rays that they need for their health. “ I remember from experiments conducted some time ago that the flies also dislike blue. A room-that was white attracted them, but when it was painted blue they avoided it. “ The suggestion that larders should be glazed in colours avoided by flies might be useful, but I have not heard of its being put into practice.”
