the warm weather of the early spring the hibernating larvae become 

 active and eat into the buds and growing tips, causing them to wilt 

 and droop. Pupation occurs under the bark or in old pruning wounds 

 about the 1st May. The adults appear about a week later and deposit 

 eggs on the stems and petioles of the leaves. The larvae of this 

 brood appear between 5th and 10th June, and at once begin eating 

 the flesh of the fruit. The life-cycle of this generation develops very 

 rapidly, the adults appearing about 20th-25th June. The larvae of 

 this generation also attack the fruit, though many of them hibernate 

 until the following spring. 



The larvae may be reached by contact sprays while they are under 

 the bark and by stomach poisons when they are feeding. From 

 experiments that are still in progress it would seem that a combination 

 spray of lime-sulphur and lead arsenate (neutral or basic) will control 

 A. lineatella, as well as peach leaf-curl and peach blight, if applied as 

 the buds are swelling. Exceptionally good results were also obtained 

 with nicotine sulphate and zinc arsenite.

A species of Eriophyes is recorded as injuring various varieties 

 of figs, and another as attacking the green and ripening fruit of Himalaya 

 blackberries, in California. The nature of the injury is described, 

 and experiments are planned with a view to ascertaining to what 

 extent these mites are responsible for this injury and the best means 

 of controlUng them.
