INSECTS OF THE GARDEN. 



RUFUS H. PETTIT. 



' Bulletin No. 233. 

 INTRODUCTION. 



The present bulletin is the second of a series dealing with the insects 

 affecting different classes of crops. It deals with the insects now affect- 

 ing garden and truck crops in Michigan and some which are sure to be 

 found in the State sooner or later. Only insects of importance or of in- 

 terest have been included. Most rarities have been omitted in order to 

 prevent confusion. 



Many facts have been drawn from the writings of others, notably from 

 those of the Department of Agriculture at Washington; from the bulle- 

 tins of Professor Slingerland of Cornell University; from the Canadian 

 reports; from the bulletins of many of our State experiment stations. 



It must be borne in mind that insects affecting truck crops and those 

 of the garden as well, very often work also in field crops and in grains. 

 It is not the purpose of the writer to enter upon the subject of field 

 and grain crops in the present bulletin, that phase of the subject being 

 reserved for the future. Methods of use in small areas are often useless 

 in large fields, thus in the case of sweet-corn it often happens that 

 methods which would not pay in large fields, will be of good service in 

 smaller areas where the cultivation is more intensive and the price re- 

 ceived for the output will warrant more outlay in case of an emergency. 



The illustrations are from various sources. Credit is given in each 

 case where the source is known. 



On pages 65 to 07 are given the methods of preparing the insecticides 

 recommended in this bulletin. 



The entomologist is always glad to receive specimens of insects or 

 of their work, and in return to name them when possible and to give 

 advice as to control. Send specimens, if possible, in tight tin boxes 

 with few if any holes. 



The first bulletin of this series dealing with fruit insects is number 

 24, special. This is to be had on application as long as the supply lasts. 

 It is. intended that other bulletins of like nature will be issued on field 

 crops, pests of forest, shade and ornamental trees, etc., if there seems 

 to be a demand for them, and these if preserved, with the rest of the 

 series may prove useful for reference. 



Always send specimens of insects to the 



Entomologist of the Experiment Station, 



Agricultural College, Mich.
