INSECTS AND INSECTICIDES 
By C. P. Gillette. 
The present bulletin is issued to supply the constant call for 
information in regard to the common insect pests and the rem¬ 
edies that are commonly used for their destruction or prevention. 
It is really Bulletin 71 revised and somewhat enlarged. The most 
important additions are the short articles upon two Currant and 
Gooseberry insects, the Currant and Gooseberry fruit maggot and 
the Currant and Gooseberry fruit worm. The most important 
omissions are in cuts of spraying apparatus. 
No attempt has been made to include all of the insects in¬ 
jurious to fruits in the State, nor to give the methods of preparing 
all the insecticides of importance. The station will be glad to re¬ 
ceive inquiries concerning any other insect pests that may be 
troublesome in any manner to residents of Colorado. Always 
send specimens of the insects and their injuries when possible and 
give as much information in regard to habits and injuries as you 
can. Fuller information in regard to any insect mentioned in this 
bulletin will also be given upon request. 
In the second part of this bulletin the insecticides mentioned 
are numbered, so that in the first part, which treats of injurious 
insects, the remedies recommended in each case are referred to by 
number for the sake of brevity. 
Many remedies that are rarely of importance and other sup¬ 
posed remedies that are of little or no use, are left out of this bul¬ 
letin. The attempt is to give the more important remedies for 
use in this State.
