856 EXPERIMENT STATION RECORD. 



Root crops and vegetables (pp. 243-250). — Few complaints were received, 

 but tbe following insects are noted: Turnip flea beetle (Phyllotreta 

 vittata), red turnip beetle (Entomoscelis adonidis), which did consider- 

 able damage in the Northwest Territories and in Manitoba; striped 

 cucumber beetle (Diabrotica vittata), clover cutworm (Mamestra trifo- 

 lii), zebra caterpillar {Mamestra pieta) 7 which was abundant in the 

 western parts of Ontario, but was much affected by the parasites 

 Trichogramma pretiosa and Telonomus sp., and by Apanteles; small 

 white cabbage butterfly (Pieris rapce), which affected turnips as well as 

 cabbages injuriously; Colorado potato beetle (Doryphora 10-lineata), 

 and red backed cutworm (Garneades ochrocjaster). 



Fruits (pp. 250-264). — There are noted the codling moth (Garpocapsa 

 pomonella) eye spotted bud moth (Tmetocera ocellana), cankerworms, 

 cigar case bearer (Coleophora fietclierella), oyster shell b;irk louse (Mytil- 

 aspis pomorum), pear tree slag (Eriocampa eerasi), plum webworm (Lyda 

 rufipes), San Jose scale (Aspidiotus perniciosus), which was discovered 

 in Vancouver Island, where the pest must have existed on the trees 

 affected for sometime; plum curculio (Gonotracheltis nenuphar), grape 

 phylloxera (Phylloxera vastatrix), peach bark borer (Phleeotribus limi- 

 narisj, black peach aphis (Aphis persicw-niger), apple maggot, and 

 apple fruit miner, which has become a serious enemy to the apple 

 growers on the Pacific Coast, where it attacks the apple at about the 

 same time and in much the same way that the apple maggot does in 

 the East. The apple fruit miner is abundant in the wild crab, and its 

 habit of attacking apples seems acquired and exceptional, but persist- 

 ent. Appended to the foregoing is a note on the horn fly (Rcematobia 

 serrata). 



Experiments in wintering bees, J. Fixter (pp. 264-271). — During 1895, 

 189 f; , and 1897 experiments begun in former years were continued. The 

 most satisfactory way of wintering in a cellar was found from these 

 experiments to be the following: Hives are placed in the cellar, raised 

 from the floor by empty hives or other means, and arranged in tiers 

 with the back of the hive raised somewhat higher than the front, and 

 each hive raised from its bottom board by a small block § in. high. All 

 front entrances are left wide open so as to give free ventilation. The 

 wooden covers of the hives are replaced by chaff cushions 4 in. thick, 

 above which are placed strips of wood to prevent their coming in con- 

 tact with the hives above. In hives packed with sawdust, preventing 

 ventilation, bees were smothered, and in hives similarly treated, but 

 with ventilation, the colonies were weakened by heat, dampness, and 

 insufficient ventilation. Hives packed with chaff and left out of doors 

 on the ground without ventilation, or with none other than the ventil- 

 ating shaft, were found to have been sufficiently protected, but in the 

 former case to have suffered considerably from water which found its 

 way into the hive. 



Notes are also given on buckwheat, 5-bauded Italian bees, a hive in
