ENTOMOLOGY. 871 



to prevent peach-leaf carl, peach and plum rot, and the orange rust of 

 the quince. Different strengths of lysol, copper sulphate, and Bordeaux 

 mixture were employed. The lysol was apparently without much effect. 

 The trees which were sprayed with copper sulphate developed pencil 

 yellows, and were destroyed before harvest, while the Bordeaux mix- 

 ture proved very efficient in preventing the leaf curl. Bordeaux 

 mixture made from 3 lbs. copper sulphate and 3 lbs. of lime to 1 barrel 

 of water is recommended for application on peach and plum trees. 



During the summer of 1897 plum, cherry, and apple trees were se- 

 verely attacked throughout Ontario and Quebec by aphides, nursery 

 stock and young orchard trees suffering the most. Experiments were 

 conducted with kerosene emulsion, tobacco water, tobacco water and 

 lemon oil, quassia chips and whale-oil soap for the destruction of these 

 insects, and it was found that where cheapness and efficiency is con- 

 sidered, tobacco water with whale-oil soap produced the best results. 

 Tobacco water and lemon oil gave the most decisive results, but the 

 addition of lemon oil increases the cost of the solution. In spraying 

 for the destruction of these insects care must be exercised that the 

 liquid shall reach the under surface of the leaves, and 2 or 3 applica- 

 tions at intervals of a few days should be made in order to destroy the 

 different generations of the aphides.

 (Primus capollin) in that region, namely, Anthonomus (Tachypterus) quadrigibbus, 

 Clisiocampa fragilis var., and Coleophora sp., and the public is cautioned against 

 their threatened introduction into orchards.
