TENTH REPORT OF THE STATE ENTOMOLOGIST 497 



On Arsenical Spraying of Fruit- Trees While in Blossom. 

 (Insect Life, vi, 1893, pp. 181-185.) 



It is still a question if the observed mortality of bees visiting sprayett 

 blossoms is the result of the arsenic or some other cause or causes. The 

 experiments of Professors Webster and Cook are cited. A satisfactory test 

 would be the examination of the stomachs of bees believed to have been 

 poisoned by the arsenic. Legislation in Ontario against spraying fruit-trees 

 while in blossom. May arsenic blight the blossoms? Until the harmlessnesa 

 of spraying at this time can be established it should be discontinued, but if 

 harmless it should not be intermitted during the blossoming season, when 

 several pests can be better controlled than at any other time. Seventeen 

 species are named which are operating destructively at this time.
