Brittain (W. H.). Hydroecia micacea as a garden pest. — Proc. Entom. 

 Soc. Nova Scotia, Truro, no. 1, 3rd August 1915, pp. 96-97. 

 [Received 28th June 1916.] 



In the early summer of 1914 a boring caterpillar appeared in large 

 numbers in the rhubarb plantation on the Nova Scotia Agricultural 

 College Farm and practically destroyed the crop. The adults have 

 been identified as Hydroecia micacea, Esp. No sign of injury is noticed 

 until about mid-June or later, when the leaves begin to wilt, and on 

 cutting into an injured plant the larvae will be found boring in all 

 directions through the crown or in the stem. Late in July or early 

 in August the larvae pass into the ground and enter the pupal stage. 

 The adults emerge during August and September. The first eggs were 

 found on 31st August, the favourite place of deposition being the stems 

 of Agropyron repens (couch grass) which was abundant in the rhubarb 

 plantation. This fact indicates the necessity for destroying all weeds, 

 etc., upon which the eggs are hkely to be laid. Besides injuring 

 rhubarb, H. micacea has done considerable damage to potatoes. This 

 pest is of European origin and in England is known as the potato 

 stalk borer. A bibliography of twelve works concludes this paper.

 ceana, Harr. — Proc. Entom. Soc. Nova Scotia, Truro, no. 1,

Tortrix (Archips) rosaceana, Harr. (oblique-banded leaf-roller) is 

 one of the commonest leaf-rollers in Nova Scotia, where it does con- 

 siderable damage to the foliage in spring and early summer and again 

 in autumn. The partly grown larvae pass the winter in small 

 nests found at the tips of the twigs and fruit spurs, hidden under small 

 pieces of bark, dead leaves or bud scales. When the tips of the buds 

 show green, the minute caterpillars emerge, feeding on the tender 

 foliage and boring into the centre of the bud. As the leaves unfold, 

 the larvae leave the buds and feed upon the new fohage, rolhng and 

 tpng down the edges of the leaves so as to form a shelter within which 

 they feed and rest. When mature, usually in the second half of June, 

 they transform in their nests to pupae from which the adults emerge 

 in about two weeks. There is only one brood a year in Nova Scotia. 

 Descriptions of the egg, larva and pupa are given.

 in West Africa ; a few species collected in the Cape Verde Islands by 

 L. Fea are also included. Many of the species are new.
