agriculture ; and the great bene lit that may be obtained by extending 

 protection to them is here emphasised. Some of the most important 

 birds economically are crows, particularly as enemies of the blow-fly, 

 screech owls, plovers and quails, while almost all birds live on insect 

 food during their nestling stages.

 Aphis and Codling Moth. — 14th Ann. Rept. Dept. Agric. 1919, 

 Victoria, B.C., 1920, pp. Q 27-31. 



In attempts to find an efficient and cheap spray for the green apple 

 aphis [Aphis pomi], various combinations of insecticides were tested. 

 Of these Blackleaf 40 (1 to 2,000) and slaked hme (2 lb. to 100 gals, 

 water) is advocated as efficient and cheap. 



Work in connection with codling moth [Cydia pomonella] was 

 continued, and although an increased area has been brought under 

 treatment, there is a decrease in the percentages of captures made.

The pests intercepted include : Aspidiotus perniciosus (San Jose 

 scale); A. ostreaeformis ; Aulacaspis rosae (rose scale); Lepidosaphes 

 iilmi (oyster-shell scale) ; Pulvinaria innumerabilis ; Icerya sp. ; 

 Saissetia [Lecanium) hemisphaerica ; Coccus {L.) hesperidum ; 

 Diaspis sp. ; Chionaspis sp. ; Aegeria (Sanninoidea) exitiosa (peach 

 root borer ; Pennisetia [Benibecia] marginata (blackberry crown 

 borer) ; Phylloxera ; Eriosoma lanigenim ; E. pyri ; and the eggs of 

 the gipsy moth [Porthetria dispar]. 



The recent occurrence of codling moth [Cydia pomonella] in 

 Californian walnuts has necessitated extra precautionary measures 

 against the entry of infested material. Considerable damage is 

 caused to stored peanuts by Plodia inter punctella.

Weather conditions in Alberta during 1919 were very favourable to 

 insect pests, and in consequence, the most serious losses occurred to 

 crops that have been recorded for some years past. Cutworms, 

 especially Eiixoa ochrogaster (red-backed cutworm), were particularly 

 troublesome in both fields and gardens ; it is suggested that in dry 

 seasons favourable to their increase, sowing should be delayed in 

 gardens until the ground has been treated with poison-bait. Other 

 injurious cutworms were Porosagrotis orthogonia, Morr., Agrotis 

 (Noctiia) fennica, Tausch., and Euxoa tristiada, Morr. Loxostege 

 sticticalis (beet webworm) and Psylliodcs punctulata (hop flea-beetle) 

 were both injurious to beets. When the latter is troublesome on hops, 

 it is usual to place tarred paper beneath the vines and then brush them 

 with a feather duster. 



Malacosoma disstria (forest tent caterpillar) continued to be as 

 troublesome as in the previous year [R.A.E., A, vii, 544], and an attempt 

 is being made to introduce a Tachinid parasite of it [Blepharipeza] from
