CURRANT AND GOOSEBERRY PESTS. 97 



throughout the summer and autumn, and enlarging the 

 size of their tunnel home both in length and breadth as 

 they increase in size. Just before changing to a chrysalis 

 the larva excavates a passage nearly through the stem, 

 only leaving the thin outer skin unbroken to protect the 

 puj^a from harm. Early in the following June the pupa 

 pushes itself against this skin, so as to rupture it, and 

 then, jerking uself half-way out of the newly-formed 

 opening, rests for awhile. In a short time the skin of the 

 chrysalis cracks and the perfect insect emerges, dries, 

 expands its wings, and flies off. The larva when full 

 grown measures barely half an inch in length ; its body is 

 a pale yellowish tint, with the head a light chestnut 

 colour, and the jaws slightly darker. It has sixteen feet 

 — i.e., three pairs of claw-feet, four pairs of sucker feet 

 beneath the body, and one pair of sucker feet beneath the 

 tail. 



ItEMEDiES. — In detecting the presence of this pest in its 

 larval stage the fading condition of the leafage will be a 

 pretty obvious guide. Everj^ infested shoot should be cut 

 off well below the bottom of the tunnel, so as to ensure 

 having cut away the larvjie, and at once burnt. If the 

 infested shoots are not at once burnt, but only cut off 

 and thrown on one side, the larvi^e are pretty sure to com- 

 plete their metamorphosis, and appear again in due 

 course. 



Currant Pug Moth (Eupithecia assimilata).— The 

 larvjTE- of this moth feed upon the foliage of the currant. 

 The moth is small, of a blackish-brown colour, marked 

 with a grey line. It appears in May and June. The 

 larvae are yellowish-green in colour, with a line of darker 

 green on the back and down each side. They are most 

 active in late summer and early autumn. 



Kemedy. — Spray in autumn with Formula No. 10. 



Currant Shoot Moth (Incurvaria capitella).— The 

 larvae of this moth have been found to injure the young 

 shoots of currant trees by boring into and feeding upon
