The area invaded by the Mexican bean beetle [Epilachna conupta, 

 Mills.] in Alabama is much greater than had been previously deter- 

 mined ; it is also established in Georgia, Tennessee, Kentucky and 

 South Carolina, indicating a fairly general dissemination throughout 

 the South and making extermination or even effective quarantine 

 control impossible. As a result, Quarantine no. 50 [R.A.E., A, x, 275] 

 was revoked 23rd July 1921. 



A new quarantine has been declared against the States of New 

 Hampshire and Massachusetts owing to the occurrence of the imported 

 pest, Stilpnotia salicis, L. (satin moth). This quarantine, no. 53, 

 became effective on and after 1st January 1922, and prohibits the 

 movement of any species or variety of poplar {Populus) and willow 

 [Salix) from any infested area within these States to or through an^^ 

 other district not known to be infested. 



Owing to a sudden outbreak of Pseudaonidia (Aonidia) duplex, 

 Ckll. (camphor scale) [R.A.E., A, x, 73], a Federal quarantine in 

 this connection has been discussed, but is not considered to be necessary 

 at present, as the State quarantine established by the Department 

 of Agriculture of Louisiana is being operated effectively in co-operation 

 with the United States Department of Agriculture, and provides for 

 the inspection, and if necessary fumigation, of any florist stock or 

 similar material leaving New Orleans for outside points. In the estimate 

 for 1922 about ^^3,000 (at par) is requested lor investigation and 

 control of this new pest. 



The fumigation of shipments from France of fruit and rose seedlings 

 infested with nests of the brown-tail moth [Nygmia phaeorrhoea, 

 Don.] has proved to be an unreliable means of disinfection at tem- 

 peratures below 50° F. and has therefore been discontinued, such 

 shipments being refused entry. 



B}^ arrangement with the customs seivice and post office department 

 the importation, through the mails, of special permit material under 

 Regulation 14, Quarantine no. 37 [R.A.E., A, x, 275] will hereafter 

 be authorised on request, when warranted by the nature and amount 

 of the proposed shipment. 



A list of the current quarantine and other restrictive orders is given.
