THIRTY-FOURTH FRUIT-GROWERS ' CONVENTION. 



hands over to the treasury of the nation a much larger sum. If it is 

 true, then, that our country receives at the hands of agriculture seven 

 billion dollars annually, and if, as is shown by experts, we suffer a lass 

 of one fifth of this because of insect ravages, then surely the question 

 of insect control is a momentous one. California is to the fore front in 

 this enormous production; except for her intelligence and enterprise, 

 she would also excel in loss by her insect foes. It is also true that we 

 spend — wisely spend — thousands of dollars annually to hold these pests 

 in check. I know of a single orchard where $22,000 to $33,000 have 

 been expended annuall}' to protect against these ubiquitous foes. 



]\Ir. Ehrhorn, in his valuable address at the Marysville meeting, and 

 our wideawake Commissioner Pease here to-day, have shown us what 

 substantial aid has come to us from our insect friends — predaceous and 

 parasitic — and surely the astute orchardist will receive valuable sugges- 

 tions which should lead to more valuable action in the premises. 



It is desirable that we have the correct names of such insects as filch 

 from our hard-earned possessions, as also of our insect friends, and so 

 I make no apology for appending the following tables, with the anno- 

 tations. I will first give the destructive insects that I have myself seen 

 at work, the most of which, and the most destructive of which, are the 

 several scale pests :
