Late in 1921 two new points of infestation were discovered in the 

 most important cotton section of Texas, their origin being traced to 

 seed shipped from Carlsbad, New Mexico. Emergency quarantines 

 were immediately placed about these districts. In view of the 

 possibility of a wide new infestation a cotton-state pink boUworm 

 conference was held 2nd December, at which the continuance of 

 efforts, both State and Federal, for the extermination of the pest 

 in Texas and other southern states was recommended and unqualified 

 assurances of support were given. The policy of maintenance of 

 non-cotton and regulated zones was endorsed. The enforcement of 

 these zones was confined to the eastern districts, because of the close 

 proximity of the western districts to Mexico and the consequent 

 impossibility of maintaining freedom from the pest until adequate 

 co-operation with IMexico should have been secured. In this con- 

 nection the isolation of these districts from the main cotton belt has 

 also been taken into consideration. The plans for the control work 

 in 1922 are outlined. As far as is known, P. gossypicUa has been 

 completely exterminated from Louisiana, but precautionary control 

 measures are being continued, though with the exception of the 

 district about Shreveport all non-cotton zones are being discontinued 

 for 1922, and the regulated areas are being released, only field 

 inspections being continued in them. 



The Quarantine Order no. 3 of the vState of New ^lexico for the 

 prevention of the introduction and dissemination of the pink bollwomi 

 is being enforced, and the Federal Quarantine no. 52 has been recognised 

 and made part of the New Mexico regulations. 



The present distribution of P. gossypiella in the \\'est Indies is 

 recorded. As a result of the extent of infestation in Porto Rico and 

 its occiuTence in Santo Domingo, a general campaign of eradication is 

 considered inadvisable ; complete eradication from these larger islands, 

 in view of the cultural conditions and the abundance of wild cotton 

 there, would seem impossible, and the}^ would be a constant source 

 of reinfestation for the smaller ones. The infestation in the West 

 Indies is considered to be the result of the importation of Egyptian 

 cotton seed in 1911-12 into the Island of St. Croix. By the existing 

 quarantine the United States are protected from the movement of 

 cotton, cotton seed, etc., from the West Indies. 



The foreign quarantine on account of the European corn borer 

 [Pyrausta nubilalis, Hb.] (no. 41) has been revised to include the 

 restriction of the importation from Canada of various products known 

 to be possible means of spreading the pest in addition to maize. 

 Following the conference held at Sandusky [R.A.E., A, x, 138], 

 Domestic Quarantine no. 43 [R.A.E., A, viii, 511] has been revised 

 to include the new areas of invasion R.A.E., A, x, 217] and the 

 regulations have been somewhat modified. 



By the amendment to the regulations of gipsv moth [Porthetria 

 dispar, L.] quarantine (no. 45) ten towns in New Hampshire, Massa- 

 chusetts and Rhode Island have been transferred from the category 

 of lightly infested to that of generalh^ infested areas. 



As a result of the increasing spread of the Japanese beetle ^Popillia 

 japonica, Newm.] it has been found necessar}^ to extend the areas 

 under restriction in Pennsylvania and New Jersey, and a corresponding 

 revision of Quarantine no. 48 has been made, to become effective on 

 and after 1st January 1922.
