 Mississippi and is heinj; intensively studied. 



The experts enj^'^god in the invest ij^it ion of insects a ffectine stored products have 

 Iteen at work upon the in.sects attacking wheat, corn, and other grains in farmers' 

 liins, warehouses, p™*" cars, ships, ami elevators. Intensive studies have ln'cn 

 made of the Angoumois grain moth, or fly weevil, that has done much damage to the 

 litliJ crop of winter wheat in the Eastern States. Investigations have heen carried 

 on in cooj)en»tion with the Bureau of (Chemistry to discover a more satisfactory fumi- 

 gant for grain cars, and studies have heen made of weevils attacking heans, i>eas, and 

 cowpeas in storage. Inst>cts affecting fahrics made of wool, hair, furs, ancl feathers 

 have heen stu<iied. 



Many important studies have heen continued with reference to hee culture, all the 

 prohlems of imi>ortance to practical beekeeping being borne in mind. 



THE DECREASES SUBMITTED. 



The amount for statutory salaries is reduced in the estimates by $-t,000, which is 

 explained by the fact that five preparator i)laces at $840 have been dropped. 



The amount submitt<'d for the investigations of the gipsy moth and brown-tail 

 moth is $')31,00(), which is an apparent decrease of .ffJQ.OOO from the amount aj»pro- 

 priated h\st winter. However, as .$100,000 of the amount apj)ropriated last year was 

 set aside as immediately available, on account of the lateness of the season only 

 tt portion of it was spent before the end of the fiscal vear, leaN-ingan actual decrease 

 of $39,292. This, with the decrease of .statutory- salaries ($4,200) is $43,492. which 

 shows a total decrease of estimates from last year's appropriation of $492. 



THE INCREASES SUBMITTED. 



Under deciduous fruit insects, an increase of $25,000 is requested, $20,000 of which 

 is to provide for the strengthening of the work against the Japanese beetle. The ra{>id 

 spread of this beetle ami the tremendous increase in its destructivene.ss durinj;; the 

 past year have so increased the i)roblem of its control that an entire reor^r-mization 

 of the work will be necessary. It is projKwed to abandon the project of certification 

 and inspection of fielil crops, such as sweet corn, etc. The area of infestation now 

 includes so many large nurseries that the. expense of inspecting nursery stock will 

 require all the funds available for in-senction, leaving the increase asked for to provide 

 for the extension of research work ana the develo])ment of control measures. If the 

 continuation of the field inspection work is to be considered, this will neOd to be done 

 on an entirely different basis from that in effect at present and will involve much 

 larger sums of money than this appropriation ])roviiles. 



The other $'»,000 of the $2"),(K)0 asked for will be exjiended in the investiiiation 

 of pecan insects, especially the green soldier bug and the pecan-nut case borer which 

 have recently become seriously destructive in Georgia and Florida. This investi- 

 gation is urgently demanded by pecan growers in the Southeastern States.
