CHAPTER XVI 



INSECTS INJURIOUS TO THE GBOSELLES 



Like all other economic plants, the groselles are 

 subject to attack from insects of divers character, 

 appearance, and habits. Some only take a passing 

 bite, like the schoolboy who devours beech leaves, 

 ''sweetbrier," birch, etc., to appease his ceaseless crav- 

 ings in the long hours from meal to meal. Others, 

 indifferently feeding upon whatever plant is available, 

 may at times eat more than we wish. Still others, on 

 evil bent, assiduously seek out our cherished bushes 

 and settle down to a steady diet of groselles with all 

 the persistence characteristic of their race. The list 

 immediately following comprises those most likely to 

 work serious injury.

Pcecilocapsus lineatus (Fabr.). -Order Hemiptera. Family Capsidse.

This is a native insect which was first described by Fabricius 

 in 1798. It came into notice as injurious to dahlias, currants and 

 other plants soon after the middle of the present century, and has 

 never ceased its evil ways from that day to this. Its food plants 

 embrace esculent and ornamental plants and a few weeds.
