284 FRUIT AND ITS CULTIVATION, 



Other Pests. The larvae of the Winter Moth eat the 

 foliage; those of the Currant Clearwing Moth bore into* 

 the shoots; the Currant Sawfly larvae devour the foliage; 

 and the Currant Aphis and Brown Scale suck the sap out of 

 the leaves and shoots. See other sections for descriptions. 



Nut Pests. 



Filbert Bud Mite (Eriophyes avellanae). A mite allied 

 to the Big Bud Mite of the Black Currant. The mites 

 live in the scales of the buds, suck out the sap, and cause 

 the buds to swell to an abnormal size. They commonly 

 infest the buds of the Wild Hazel. Picking off and burn- 

 ing the swollen buds is the only remedy. 



Nut Weevil (Balaninus nucus). The weevils, which are 

 tawny coloured and about iin. long, bore a hole into the 

 young nut with their beaks or rostrums, and then deposit 

 a single egg therein. In about ten days a creamy-white 

 maggot appears, and feeds on the kernel until it is full 

 grown ; then it gnaws its way out, descends to the soil, 

 forms a cell, and remains therein till spring, when it 

 pupates, and appears as a weevil in June. The weevils 

 feed on the foliage during the summer. Spraying the 

 foliage with an arsenate of lead wash in June seems to be 

 the only way of killing the beetle. 



Other Pests. The larvae of the Winter, Mottled Umber, 

 and Buff-tip Moths, also various leaf weevils, feed on the 

 foliage. 



Peach and Nectarine Pests. 



Peach Aphis (Aphis amygdali). A species of aphis 

 which infests the young foliage, sucking out the sap, and 

 causing the leaves to curl. Spraying with a soft soap 

 and quassia solution is the only remedy. 



Peach Scale (Lecanium persicae). Usually attacks 

 Peach trees grown under glass only, but is occasionally 

 to be found on outdoor trees. Infests both leaves and 

 shoots, and is best got rid of by spraying the trees in 

 winter with a caustic alkali wash.
