CHAPTER IX 



INSECTS AFFECTING THE BRAMBLES 



The insects attacking the genus Rubus are many, 

 and to attempt to adequately discuss them all would 

 far exceed the limits of space which can profitably be 

 allotted to the subject. Nevertheless, it seems wise to 

 list, in so far as possible, all which are known to attack 

 plants of the genus in any way, and to give a few of 

 the more important and most easily accessible refer- 

 ences to literature on the subject as an aid to those 

 who may have occasion to study any of the species 

 mentioned. To make original observations concerning 

 any considerable number of these species would have 

 been impossible even for an entomologist. In the case 

 of those species considered really injurious, the aim 

 has been to collect and present in condensed and con- 

 venient form the more important facts already known 

 about them, together with the methods which at pres- 

 ent seem most feasible for combating them. WhHc 

 it is to be hoped that these brief statements will, 

 in most cases, be sufficient to aid the busy man who 

 must meet the insect and meet it at once, the refer- 

 ences will doubtless prove far more helpful to any 

 who may wish to make a more careful study of the 

 subject. Original illustrations of the species of great- 

 est economic importance are added. These are drawn
