water, applied by 15th June, will therefore control it. Where the 

 second spray for the first brood of codling moth [Ci/dia pomonelki] is 

 usually applied by this date, no special application will be reipiired. 

 Young orchards should receive the arsenical spray as soon as this pest 

 appears in numbers sufficient to cause any serious damage. Lime- 

 sulphur solutions or Bordeaux mixture may be added if required. 

 The bulletin closes with a bibliography of 13 references.

To control Eriocampoides limacina the foliage should be dusted with 

 newly slaked lime. For cherry trees in orchards, arsenical sprays may 

 be used as soon as the gathering of the fruit is over. Trees which are 

 attacked need stimulating to counteract the ravages of the insect, and 

 the application of fertilisers to the soil is therefore advised. The 

 following mixture may be dug in round the roots of the trees in the 

 proportion of 4|- oz. superphosphate, 1| oz. potassium sulphate 

 and 1| oz. ammonium sulphate to every square yard, or a liquid 

 manure may be applied.

The pests dealt with here, include : — Eriosama lanigerum (woolly 

 aphis), Cydia pomoneUa (codling moth), and Caroecia responsana (light 

 brown apple moth), of which the two last-named are very destructive 

 to apples and are controlled by lead arsenate sprays ; Tefraw/chus 

 iekirius (red spider) found on all fruit, vegetable and garden plants, 

 which can be controlled by tobacco water in summer and red oil in 

 winter. Ngsius vinitor (Rutherglen bug) severely damages peaches, 

 apricots and tomatoes, but fortunately only appears in vast numbers 

 once in about 10 years and should be checked by benzole emulsion or 

 tobacco sprays ; smudge fires sprinkled \nth sulphur are also a 

 successful remedy. A good spray consists of 1 quart phenyle, 3 lb. 

 washing soda, and 1 bar yellow soap, dissolved in 40 gallons of hot 

 water. 



Mi/zxs sp. (green peach aphis) should be checked by lime-sulphur 

 wash or red oil, while the trees are dormant ; the Scarabaeid, Diphuce- 

 phahi colasjndoides, Gyll. (cherry green beetle), originally a tea pest, 

 now attacks many fruits and garden plants. Smudge fires should be 

 tried, and trees sprayed with arsenate of lead before the fruit ripens. 



Icerya purchasi, Msk. (cottony-cushion scale) is a well-known pest 

 on orange, lemon, acacia, and other trees and plants. Red oil, 

 lime-sulphur and kerosene emulsion sprays are used as controls. 

 Aspidiotus hederae. Vail., {nerii, Bch.), is a common greenhouse and 

 garden pest, against which red oil and lime-sulphur are used. Metura 

 ehngata, Saunders (case moth) is controlled by arsenical sprays, 

 Paris green or arsenate of lead. Phalaenoides {Agarista) glycina, 

 Lewin (vine moth) increases very rapidly on vines, and should be 

 sprayed with arsenate of lead. HeUothis obsoleta,¥. {armigcra, Hb.)
