the south end of the Okanagan Valley. It is successfully controlled 

 by arsenate of lead sprays. The neglect of the peach trees during the 

 last few years has led to the spread of this moth to apricot, plum and 

 prune trees. Two specimens of the apple maggot fly (Rhagoletis 

 ■pomonella) Avere taken at Penticton in August, this being the first 

 authentic record of the presence of this insect west of the Rocky 

 Mountains, though it is one of the most destructive pests in Ontario 

 and the Maritime Provinces. The diamond-backed moth {Plutelhi 

 vmcuJipennis) has done considerable damage to root and vegetable 

 crops throughout the Lower Boundary and Columbia Valley sections. 

 The cabbage aphis {Aphis brassicae) has caused considerable, and, in 

 certain cases, total loss of crops in these districts. The cabbage-root 

 maggot, Chortophila (Phorbia) brassicae, is also on the increase in the 

 drier sections of the Province. The Colorado potato beetle {Leptino- 

 tarsa decemJineaia) has been rei^orted south of Nelson, but this requires 

 confirmation. 



The entomological outlook in the Province is generally good, con- 

 ditions arising from the war, resulting in absentee owners and neglect 

 of ranches at critical times, causing the most concern.

The legislation enacted for the control of the various insect pests 

 which may be imported into Canada is reviewed in this paper. The 

 San Jose scale {Aspidiotus perniciosas) was at first the only insect dealt 

 Avith, but the Act now includes Euproclis chrysorrhoea (brown-tail 

 moth), Eriosoma (Schizoneura) lanigerum (woolly aphis), Aidacaspis 

 pienkigona (West Indian peach scale), Lymantria {Porthetria) dispar 

 (gipsy moth), Ceratitis capitata (Mediterranean fruit fly), and Phthori- 

 maea operculella (potato tuber moth). The requirements governing 

 importations are detailed and the fumigation of imported nursery stock 

 by Federal Inspectors described. The conditions under which nursery 

 stock is allowed to be exported to the United States are also given, and 

 the paper concludes with a table showing the number of plants inspected 

 during the several years from 1909- 19 IG.

The only insect pest noted at the Sitka Station of any consequence 

 was the root maggot of cruciferous plants {Chortophila brassicae), 

 which attacked cabbages and cauliflowers, especially the latter. The 

 varieties of turnips usually grown in the United States were much 

 damaged, but the Petrowski and other turnips from Finland and 

 Sweden suffered little. The Sakurajima radish was almost totally 

 destroyed, while the common varieties practically escaped.
