 laying season, and a large number of twigs of both wild and cultivated 

 raspberries and blackberries have been killed by its egg punctures. 



(g) Hymenoptera (Bees and wasps). — The Pear-tree Slug was 

 among the most abundant of the orchard pests during the season. The

 rants and gooseberries.

 from the seed sown in the spring, and a large percentage of the developing 

 seed in the field was destroyed.
