In the ca.se of the ]nnk hollworm we ari> now af ' 



in the case of the holl weevil in spite of the poi ^ i : ._ . . :.._3 



department at that time, nearlv :$(• years apo. 



The scientific and res«'arcli plia.'H's of the Bubject have boon conduct' ' ~ ' •' 



in the l.apuna district, Mexico, and very imnortanl inf'innatir)n ' 



obtained relative to the habits and control of tne yt-^t. One in 



come of thLs work is the determination that the ^)ink boUworm 



surN-ive in moL«t soil. This determination has an important bearing on the ■ 



operations practiced by thus department in Texas and other Stat«-s -i. e., the 



tion of all standing and scattered cotton and bolls has undoubte<lly had mu 



succe-ss from (he fact that any remaining larv;e and bolls ' 



have i)erished in the moi^t soil. It ha.H been shown that \\ . ; 



from flo to 00 per cent of the larv.-e die. This work Ls beim; conductinl on a ver>- 



small appropriation ($5,00(ij, but it is ver>' dc'^irablc to con.siderably extend it, and 



a fund of $10,000 was requested for next year (1923-4). This incrcaae was not 



approved by the Budget Bureau. 



TIic corn borer. — The administration of the corn-borer atipropriation has l>oen 

 assigned to the Bureau of Entomology, but in cooperation with this board as to quar- 

 antine features. There has l)een no new outbreak of the corn borer this year. In 

 other words, this pest is still limited, so far as is known, substantially to the area.s deter- 

 mined last year, these representing for the most part areas of original infej»tation 

 from Europe in 1900 and 1010, namely, the New England area, the eastern and wpst- 

 ern New \ork areas, and the Ontario area, from which latter it has ap^ 

 a-i determined la'<t year, to the southern and western shores of I.aM 

 has I eei during the year a local but limited natural 8|)read of the insect in the case 

 of each of these areas. 



It would appear from this record that the quarantine and control m< 

 guarding the movement of products from the known infested area have pp 

 wi 'e jumps of the insect, 'i he funds available, however, for this work haw , 



entirely inadequate for general surveys of other States or areas and no tHi*>iii\e claim 

 is maile that the department now has information as to the existing distribution o( 

 this pest in the United States. 



It IS very important that the corn-borer work should be continue<l. ' ' 

 question at all as to the imimrtance of this pest of corn. It is a new pe.st 

 an adilitional burden on this crop. During the present year it has niaintauied ii^-if 

 about in the same status as pre\nously in the known areas of inl«'slation, ther. t. it ,' 

 certainly no increase of damage in the western areas of invasion in New York, I 

 vania. Ohio, and Michigan, and, in point of fact, in the.s«' areas no comnur ' 

 has ever resulted, 'ihe extensive damage which the irusoct frequently ■ 

 the New ?^ngland area seems to be explainable by the fail that the in.-' 

 double-brooded and that the cultural and croj) conditions are pfHi:!i.ul\ 

 its multiplication. The Canadian authorities report that thedn (»ntano is 



very much less than in either of the two previous years, 'l his is .-^uji . .-» vl to be duo 

 to better cultural conditions and tilivt to the late i>lanting of corn. 



'1 he menace of this pest to the main corn areas of the country i 

 It may prove to be a ven,' serious pe.«t when it rea<hes the <ji' 

 ticularly when it gets into the more .southern regions of corn culture. It i 



always have a very serious phast* in connrn-tion with table corn lor initu' 



sumption or for canning, ami in exceptional seasons with flint and {Kiwibly other 

 corn, unless efficient control bv natural I'uemies or other nieans •' ' 

 therefore every reason to continue and ade<iuaU'ly supi>orl the i 

 prevent spread.
