Insects attacking fruit were Eucosma ocellana (bud moth) on apple, 

 apple maggot [Rhagoletis pomonella], buffalo tree-hopper [Ceresa 

 bubalus], currant and raspberry sawflies and the imported currant 

 borer [Aegeria tipulifortnis]. Eriocampoides limacina (plum slug) 

 caused little damage owing to effective parasitism by the Chalcid, 

 Trichogramma (Pentarthron) minutum.

The following insects injurious to cereal crops in Quebec are recorded : 

 Mayetiola destructor (Hessian fly), on wheat, rye and barley ; Isosoma 

 tritici (wheat joint worm) ; Meromyza americana (wheat bulb-worm) ; 

 Contarinia (Diplosis) tritici (wheat midge) ; several species of locusts ; 

 Aphids, including Macrosiphum granarium iNectarophora cerealis) ; 

 army- worms ; the wireworms, Melanotus cribulosus, Agriotes mancus 

 and Drasterius elegans ; white grubs, including Lachnosterna arcuata 

 and L. rugosa. 



A key is given to the identification of the various insects attacking 

 the roots, the stems and leaves, and the ears of cereals.

Injury to cranberries by the Tortricid, Rhopobota vacciniana. Pack, 

 (black-head fireworm), was similar in extent to that occurring in 

 previous years. Efforts to control this insect by retaining the winter 

 flooding late enough to kill the eggs appeared to be successful ; in two 

 cases the water was held until the middle of June and 1st July 

 respectively, with the result that the numbers of the insect showed a 

 marked decrease and the plants were not apparently injured. The 

 Pyrahd, Mineola vaccinii, Riley (cranberry fruit worm), showed an 

 increased abundance as compared with 1913 and 1914. Cocoons 

 submerged for the period between 15th January and 31st March were 

 able to survive to an extent of 40 per cent. ; submergence until 20th 

 May was fatal to 100 per cent. The conclusion is therefore reached 

 that infestation by M. vaccinii occurring in bogs in which winter 

 flooding is retained late, originates in the upland and not in the bog
