PREFACE. 



This book is written solely with the object of placing before fruit- 

 growers, gardeners and amateurs an account of the insects, mites and 

 worms, which attack and cause disease amongst fruit trees, bushes, 

 etc., both in the open and under glass. 



Some mention is made of methods of prevention, even if they 

 give only partial relief, and also of the various forms of treatment 

 that have been adopted to destroy the insect and other enemies. 



The volume is by no means complete, but it has reached such 

 proportions that it is impossible to give all the information it was 

 hoped to. Nevertheless, all the known pests to date and all those 

 insect and allied creatures which have been recorded as having done 

 damage are mentioned. 



My thanks must be expressed to Mr. Eobert Newstead, Mr. 

 C. 0. Waterhouse and Mr. W. F. Emptage for much valuable help 

 during the writing of the work, also to so many fruit-growers that it 

 would be invidious to mention names. 



The photographs have mainly been taken for me by Mr. Edenden, 

 and a few have been prepared by Mr. Blakey, Mr. Hammond, Mr. 

 Tonge and Mr. liintoul. Professor Felt of New York, Mr. Claude 

 Fuller of Natal and Mr. Newstead have also kindly sent me photo- 

 graphs of Scale Insects and Fruit Fly damage. 



A few figures have also been reproduced from my Eeports issued 

 from the S. E. Agricultural College. 



The drawings have mostly been prepared by Mr. Horace Knight.
