NUT PESTS. Ill 



the hazel, filbert, and cob-nut. The constant irritation it 

 causes to the scales makes the bud swell abnormally. 

 Wherever the wild hazel grows in the hedges or woodland 

 it is almost impossible to prevent this mite from finding 

 its way to the filbert and cob-nut bushes in cultivated 

 plantations. 



Remedies. — The only possible remedies are to cut off' the 

 shoots containing the swollen buds, or pull off the swollen 

 buds individually. In both cases burn them as soon as 

 possible, to prevent the mites escaping. See also remarks 

 in connection with the Currant Bud Mite. 



Nut-leaf Blister Moth (Lithocolletis coryli).— The 

 larvjx- of this small and prettily-marked moth are hatched 

 from eggs laid on the leaves in May. They at once bore 

 into the centre of the leaf, and feed on the soft tissue, 

 leaving the epidermis intact, but forming white blisters. 

 The larva? pupate m the leaves, appear as moths iu 

 August, and again lay eggs. In some seasons they do 

 serious injury to the foliage. 



Remedy. — Spray in May with Formula No. 10. 



Nut-Leaf Weevil (Strophosomus coryli).— This is a 

 tiny weevil, which only measures about one-fifth of an 

 inch in length, is blackish in colour, covered with grey 

 and brownish scales, and occasionally does much harm 

 to the foliage of the filbert and the cob-nut. In some years 

 the weevils appear in considerable numbers during May 

 and June. They are not a very serious pest; hence, where 

 an occasional leaf may be found to be damaged, no notice 

 need be taken of it; but should the foliage be very badly 

 eaten, it is as well to look for the presence of this pest, 

 and to take steps for its eradication. 



Remedy. — The best remedy appears to be smearing 

 tiays or sheets with treacle or tar, and then shaking the 

 infested branches over them. The weevils, when alarmed, 

 quickly lose hold of the leaves, fall off, and are thus 

 easily caught.
