NEW ZEALAND GARDENING. 187 



As soon as the apple falls, the caterpillar leaves the fruit and 

 finds its way to the stem of the tree and secrets itself in the 

 cracks and fissures of the bark, where it assumes the 

 chrysalis form. The true larva of the codlin moth always 

 destroys the pips of the apple this will be a guide to those 

 who sometimes have their apples injured by other grubs. 



Remedies. During Winter, trees which have been in- 

 fested should be thoroughly scraped, and all loose bark and 

 primings burned. Then apply a dressing such as recom- 

 mended for Winter dressing in the case of red spider. 

 American fruit-growers resort to the following simple method 

 of trapping the caterpillars as they creep about looking for a 

 resting-place. They tie bands of old sacking round the 

 stems of the trees not far from the ground ; these bands 

 should be examined once a week, when large numbers of 

 caterpillars are usually found. During the Summer, while 

 the moths are about, cans containing vinegar and sugar if 

 hung from the trees in the orchard would trap numbers of 

 moths. Fowls do good service in an infested orchard. 

 Paris green is strongly recommended : one tablespoonful to 

 50 gallons of water, sprayed over the trees as soon as the 

 blossoms have passed maturity. A second syringing may 

 be given just before the fruit begins to turn down from its 

 increasing weight. The codlin moth has not yet found its 

 way into the Canterbury orchards. 



American Blight, or Woolly Aphis (Schizoneura lani- 

 gera}. This well-known pest is now common in most parts 

 of the Colony. Many remedies for its prevention have been 

 suggested with more or less success. The following mixtures 

 are recommended : Dissolve one pound of soft soap, one 

 pound of sulphur, and one gallon of lime in enough water to 

 make a thick wash ; apply with a stiff brush to all infected 

 parts. A good scrubbing with Gishurst's compound, four or 

 five ounces to the gallon of water, will be found servicable. 

 The dressings should be applied whenever the blight makes 

 its appearance. Remove all old bark, which should be 

 burned, together with the prunings. The soil should be 

 removed from about the stems down to the main roots, and 

 the exposed parts well painted with the mixture. This must 

 only be done in Autumn or Winter. Syringing has little 

 effect on these creatures, as they are furnished with a soft 

 downy covering which resists water.
