Recurvaria nanella, Hb., was noticed near Rome in March 1915 Hving 

 on nearly all the fruit-bearing Rosaceae. The adults appear in the 

 second half of June, becoming more numerous in the first half of July. 

 By day they shelter in crevices in the bark. The small, red-brown 

 larvae appear towards the end of August and chiefly attack the leaves 

 of peach and apricot, and to a less extent cherry, sour cherry, apple, 

 quince and pear. The almond and hawthorn are not attacked. The 

 larvae feed on the parenchyma of the leaf, leaving the epidermis 

 untouched. On the approach of winter they take refuge in crevices 

 in the bark and hibernate in a cocoon. At the time that the blossoms 

 appear in spring, the young larvae emerge and bore into the flower- 

 buds a little above the point of attachment to the peduncle. Leaf- 

 buds are also injured, the minute leaves being bound up with silken 

 threads which impede normal development. Towards the end of 

 April, the larva migrates from the green portions to the trunk and 

 branches, A cocoon is spun within a crack in the bark and from this 

 the adult emerges in June.

The ItaUan Ministry of Agriculture will grant subsidies, in some cases 

 amounting to 50 per cent, of the total cost, to associations or groups 

 of agriculturists undertaking to combat the olive-fly [Dacus oleae]. 

 The measures must be applied over the whole of a given zone of ohve 

 culture, in order to prevent reinfestation. The growers may choose 

 the method to be employed from those which have been found reliable, 

 but the writer of this article specially recommends the Lotrionte 

 system [see this Review, Ser. A, ii, pp. 289, 452, 479].
