 (Formula No. 16) just before the buds burst. 



Raspberry Sawfly (Emphytus cinctus).— The larv^ 

 of this saw fly bore their way into the pith of rasj)berry 

 canes and feed upon it, causing the shrivelling or death 

 of the canes. The grub is of a pale green hue, and about 

 half an inch long. There are two broods, and the eggs 

 are usually deposited on the under sides of the leaves. 



Remedies. — Spray in autumn with Arsenate of Lead 

 (Formula No. 10), and cut oft' and burn any canes con- 

 taining the grubs. 



Raspberry Weevil (Otiorhynchus picipcs).— This 

 weevil feeds upon the leaves of raspberries and straw- 

 berries, as well as many other plants and trees; and, as 

 it carries on its operations during the night and hides away 

 in crevices or in clods of earth by day, it is not always 

 recognised. The weevil measures about one-third of an 

 inch in length, has a peach-coloured head and thorax, and 

 body of a clayey colour. The weevil lays its eggs in sum- 

 mer in the earth, and in due course larvae of a 

 white or yellowish-white colour appear. These are leg- 

 less. They feed mainly upon the roots of crops, and are 

 sometimes specially destructive to the roots of straw- 

 berries. It is, however, with the weevil that we are 

 chiefly concerned here. 



Remedies. — Being a nocturnal feeder, the Raspberry 

 Weevil cannot be discovered by day; consequently, any 

 remedies adopted for its eradication must be carried out 

 at night when the insects are actively engaged in feeding. 

 If the foliage of raspberries is found to be very badly 

 eaten, and no insects found doing the mischief by day, 

 it may safely by concluded that weevils are the authors
