maize in Georgia, or North and South Carolina, if planted before 31st 

 March or after 10th May ; the coastal region from Virginia to Florida 

 does not, however, seem to come under any definite regulation of 

 planting. A successful and inexpensive method of spraying lucerne 

 as a remedy for the alfalfa weevil [Hypera variabilis] has been devised, 

 and successful treatments have been given against grasshoppers, 

 jointworms [Harmoliia], alfalfa seed Chalcid [BruchojyJiagus funebris] 

 and coulee cricket [Peranabrus scabricoUis]. 



In investigations on insects affecting stored products, fumigation 

 has given good results, and tests are being made with electricity for 

 deahng with insects in cereals in package form. The latter treatment 

 is promising, and should result in great saving to both producers and 

 consumers. The value of cold storage has already been proved and 

 detailed data regarding this method are being secured. The frequent 

 iospections of Army food and clothing supphes that were carried out 

 by the Bureau during the war proved so satisfactory that they have 

 remained in force and are being extended to other food depots of 

 both Army and Navy. 



Studies of fruit insects have revealed much new information 

 regarding the codling moth [Cydia 'pomonella], which has caused a 

 loss to the apple industry in one State of about £400,000. In Oregon 

 a basis of data for a spraying schedule has been obtained ; in the 

 Ozark region of Arkansas it seems that dusting cannot be substituted 

 for spraying. There are three full generations in this region and a 

 partial fourth ; a spraying schedule will shortly be prepared. Apple 

 Aphids have been studied, particularly with a view to the exact 

 determination of alternate food-plants and the identity of certain 

 forms. 



Grape pests under observation include the grape-berry moth 

 [Polychrosis viteana], which can apparently be controlled by two 

 applications of lead arsenate spray ; eventually, when there are no 

 badly infested vineyards, a single spraying should be sufficient. For 

 the grape mealybug [Pseudococcus bakeri], fumigation with sodium 

 cyanide and with sulphur fumes, particularly the latter, has been 

 satisfactory in the dormant season at night, January being the best 

 month for treatment. Spraying proved less effective than fumigation. 

 A survey has been made to determine the influence of the physical 

 nature of soils on the degree of infestation of vineyards by Phylloxera. 

 The grape sphinx moth [Pholus achemon] appeared in numbers in 

 Tulare County, California, and at an outlay of about £2,400 for labour, 

 spraying, materials and machinery, the grape crop, valued at about 

 £36,000 was saved. Against pecan insects arsenical dusts and sprays 

 Are being tried ; in some groves 90 per cent, of the nut crop was 

 lost in 1918 owing to insect injury. 



The investigations on cranberry insects have been continued. 

 On bogs badly infested with the blackhead fireworm [Rhopobota 

 vacciniana] satisfactory' results have been obtained from three 

 applications at intervals of from 17 to 21 days between 1st May and 

 1st July of nicotine sulphate containing 40 per cent, nicotine at 1 : 800, 

 with the addition of 2 lb. fish-oil soap to each 50 U.S. gals, of spray. 

 Life-history studies of this insect and of the cranberry root weevil 

 [Rhabdopterus picipes] are being completed. The latter can be 

 .controlled by spraying the foliage during May and June with 2 lb.
