 pean Corn Borer and restricting the Movement of Corn and Corn 

 Products in said Areas. Notice of Quarantine no. 2 (Domestic).

As a result of the occurrence of Pyrausta nuhilalis, Hb., in Ontario, 

 a quarantine measure was passed prohibiting the transportation 

 of maize fodder, maize stalks, including broom maize, whether used 

 for packing or other purposes, green sweet maize, roasting ears, maize 

 on the cob, or maize cobs from any of the enumerated townships in 

 the Province to points outside them, with certain necessary exceptions. 

 This quarantine was to take effect on 29th November 1920.

As a result of the inspection of foreign nursery stock several species 

 of Coccids, Aphids, Lepidoptera and other potential foreign pests 

 were intercepted, as well as living egg-masses oiHypononieuta malinellus 

 (ermine moth) in a shipment of apple seedlings from France. Owing 

 to careful scouting for and destruction of the winter webs of the 

 brown-tail moth [Nygmia phaeorrhoed], the situation in Nova Scotia 

 and New Brunswick can be regarded as satisfactory on the whole. 

 The field work was greatly assisted through the Governments of these 

 Provinces supplying half the number of inspectors required each 

 winter. No signs of brown-tail or gipsy moth [Porthetria dispar] 

 were found in the counties of Quebec during an inspection made 

 in November 1916. 



The work of controlling Hyphantria textor (fall web worm) has been 

 in progress for seven years. An unusually serious outbreak in the 

 Lower Fraser valley in British Columbia should afford valuable data 

 for investigations. 



The outbreak of Malacosoma disstria (forest tent caterpillar) in 

 New Brunswick and Nova Scotia has apparently subsided, but studies 

 are being continued in Alberta, where a severe outbreak has occurred, 

 and where the usual parasites appear to be entirely absent. 



A severe outbreak of the spruce budworm {Tortrix fumiferana) 

 on Douglas fir in British Columbia provided good material for inves- 

 tigation of the parasites of the later stages of this moth. Several 

 colonies of the predaceous mite, Hemisar copies mains, were liberated 

 in British Columbia at points where Lepidosaphes ulmi (oyster-shell 

 scale) is a serious pest. The area of investigation on the natural 

 control of Hemerocampa leucostigma (white-marked tussock moth) 

 has been extended to include the whole of eastern Canada. Conipsiliira 

 concinnata has now been successfully established against it, and 

 Apanteles lacteicolor is distributed in several counties. Calosoma 

 sycophanta has been liberated in Victoria, B.C., for the control of an 

 oak looper, Ellopia sp. In 1917 field work was begun with a view to 

 studying the relation of Lachnosterna spp. to their natural and cultural 

 environment, but owing to shortage of assistance, this work has been 

 temporarily discontinued.
