INSECT PESTS OF FARM, GARDEN AND ORCHARD 



stockman. In 1919 the live stock products were worth 

 $8,000,000,000, and it is estimated that fully 10 per cent of this 

 amount was lost through injury from insects. 



Stored Products. Even after the crops have been gathered 

 and garnered, and indeed after they and animal products have 

 been manufactured, they are constantly subject to the attacks of 

 numerous " weevils," " moths/' and other insect pests of stored 

 products. Every housewife and every merchant knows that only 

 through constant surveillance these ravages can be prevented. 

 Mills, tobacco warehouses, storage houses, and vessels, must be 

 frequently cleaned and often must be fumigated to prevent the 

 increase of insect pests peculiar to them. It is estimated that at 

 least 3 per cent of the cereal crops are destroyed by insects while 

 in storage, which would mean a loss of $200,000,000, and in many 

 cases the loss to corn, particularly in the South, is much greater. 

 The total loss due to insects in stored goods of all kinds is impos- 

 sible to estimate, but would fall not far short of $300,000,000. 

 With this brief statement of the losses due to insect pests we 

 may summarize them in a table which will show that the total 

 is based upon conservative estimates.
