 Honorable Commissioner of Agriculture, Albany : 



Sir. — This bulletin embodies the results of observations made 

 last year on four serious insect pests, three of them attacking 

 strawberries and the fourth working in greenhouses. Two of the 

 strawberry pests 'gained a place in the rogues' gallery of injurious 

 insects some years ago, but they have never before been injurious 

 in Xew York. The other insect discussed as a straAvberry pest has 

 heretofore borne a good reputation as a beneficial insect, lience we 

 were much surprised to find it capable of ruining a $350 crop of 

 fruit in two or three days. 



Two or three years ago the horticultural greenhouse became 

 infested wdth an insect which has been the most annoying pest that 

 ever infested the plants. A careful study of its life and habits, and 

 the results of the various methods used to control it are herein 

 recorded. 



The camera has enabled the author'to graphically and accurately 

 illustrate the different stages of all these insects and their work. 



This report is submitted for publication as a bulletin under 



Chapter 430 of the Laws of 1899. 



I. P. EGBERTS, 



Director.
