SWEETPOTA TO WEEVIL ERADICAnON
The sweetpotato w eevil is t he m ost d estru ctive p est of sw eetpotatoes a n d in ar eas w he re it occu rs sw eetp otato produ ction is not fe a sible without ad equate cont ro l m easures . This sm a ll insect in f ests growing pot atoes in th e f ie ld and co nti n ue s t o multiply and d ama g e potato es in stora g e. Principa l damage is d on e b y th e larva whi ch tunn el s throughout th e potato. H ea vily infe ste d sw eetp ot ato es are unfit f or hum an cons um pt ion and in many ca se s can n ot even b e us ed as f eed f or liv estock . There have b een many in stan ces of t otal d estru ction t o plantin gs. H ere in Geo r gia in 1945 a million d ollar sw eetpotato plant business was destroyed by this insect pest.
The sw eetpotato w eevil w as r eported as ear ly as 1857 in India a n d curre nt ly in th e United St ates it occurs in parts of seven southern states in cluding limited sections in Geo r g ia.
This is a coope rat ive proj ect b etw een t he d epartm ent th e U. S. Departm ent of A griculture, Agricultural Res earch Service. A st ate quarantin e is enfo rce d jointly and as of Jun e 3 0, 19 56, parts of 24 co unt ie s in volving 3 55 prop er ti es a re r egulated by this q u ar a nti ne .
In this coo pe rative era d ica t ion eff ort, a t otal of 13,90 3 manhours w ere r equ ired. Insp ections w ere mad e in 41 co unties of this st ate . During this p eriod th e sweet pot ato w eev il w as era dicate d from Atkinson and Coffee Cou nt ies.

supporting an active infestation. During 1956, 355 additional infested prop erties w ere locat ed and on ly 71 prop erties releas ed. N ew ly infested properties were fo und in eight counties wh ere sw eetpotato we evi ls had not b een previously fo und; in thr ee counti es wher e we evils had been found in past y ears but did not have activ e infestations at th e b eginning of the year; and in 13 counties alr eady supporting a ctive infestations.
Control
T h e la r g e n umber of prop erties in G eorgia wh ere sw eetpotato we evi ls w ere found for th e first time in 1955 indicated that a r evi ew shou ld b e mad e of th e proposed program with consideration giv en to r evising th e program for 1956 . On th e basis of r esu lts obtained by th e Res earch Unit in Lo uisiana on th e control of th e sw eetpotato w ee vi l with in secticid es , it was d ecid ed by State and Branch officials that in lieu of the non-planting zon es previo usl y prescribed for infested areas that sw eetpotato es cou ld be produced in such ar eas wh en insecticidal applications w ere app li ed as directed to se ed beds, fi eld plantings, vo lunteers , and to the potato es before storage.
As a r esu lt of this program, a tota l of 98,223 aggregate square yards of seed b eds were treated with die ld rin dust on 543 prop erties. F ield treatments wer e made with di eldrin dust and granular to 658 aggregate acres on 366 prop erties as of J un e 30, 1956.
Cooperation

SWEETPOTA TO PLANT CERTIFICATION
In ord er t o prevent the introduction into and spread within th e state of stem rot, b lack rot and mosaic of sw eetpotato es , the d epartm ent m a int a ins a compu lsory sw eetpotato plant certification program. T h e p lants are insp ected in the fi eld a nd s eed stock inspected in storage. If no dis ease is fo und and the plants are not grown within a two m ile radi us of a sweetpotato we evi l infestation, certification is granted and the grower f urnish ed with certificate tap e and t a gs. Thro ugh this program the spread and b ui ld up of inju rio us insects and diseases is prevented and commercial or other sweetpotato growers are assured of dis ease-f r ee plants.

heading of General Pest Contro l. These includ e Im por t ed Fire Ant Survey, Pink Bollworm Survey, Cotton Certification, European Corn Borer, Kha pra Beetle, and Veda lia Beetle . Other activities included the inspection of various seeds and plants for insects and plant diseases to meet r equirements for shipment to for eign countries; information on househo ld and structural pest cont r ol ; observations for the pres ence of th e so ybean cyst nematod e; lectures and d emonstrations to farm and civic organizations; ed ucat ion a l exh ibits at various state and co unty fairs; and fi eld trips as ne eded on insect and p lant dis ease control.
Imported Fire Ant Survey
Surveys w er e cond ucted during th is pe riod to d eterm in e th e extent of Im por t ed Fire Ant infestations in this state . Due to lim it at ions imposed by a lready heavy work loa ds, it was n ecessar y to r estrict t his survey fo r th e m ost part to observations in co n n ectio n with r eg ular n ursery inspectio ns . Whi le the m ovem en t of n urs ery stock ha s to date been the biggest factor in th e introduction of t his pest int o Geo rgia , t h e time of year w he n n urs ery insp ectio ns are mad e is not th e best time to loca t e incipient infestations of Im por t ed Fire Ants. T h e danger of this insect to the various agricult ura l interests and th e gen era l w elfare of this state is increasing at an alarming rate and an aggressive control program will b e n ec essary to cop e with this probl em. To date infestations are known to occur in 6 counti es.
Pink Bollworm Survey
This insect poses on e of th e most serious threats t o agriculture in Georgia . In south T exas al on e in 1952 t he est imated damage to cotton ca use d by this inse ct was 30 mi llion dollars . At th e pres ent tim e th e pink bollworm is known to occur in six states, th e closest to Georgia b eing Louisiana. The pink bollworm is not known to occur in Georgia . Each y ear a survey is mad e in th e principal cotton growing areas of t h e state by th e departm ent and th e U. S. D epartment of Agricu lt ure for t h e pres enc e of this cotton p est. In this surv ey samp les of gin tras h are coll ected and exa m ine d . During th is reporti ng period sa mp les were co ll ected f ro m 37 co unties and 873 b us he ls of g in tras h w ere exam in ed w it h negative results.
Cotton Certification
Growers desir ing to ship cotton seed to oth er states and countries are r eq uir ed to obtain certificates of fre edom fro m insects and diseases from this departm ent. To m eet the r eq uirem ents of th e various states and for eign countri es this
13
department inspects the cotton fi elds and gi nning faci lities of all growers r eq uesting such inspections. To avoid duplication, arrangements ha ve been m a d e wh er eby insp ection s a nd cert if icates of t h e Georgia Crop Im pr ovemen t Association ar e accepted in all cases other than shipment to for eign co untries. Insp ect ions by this department are confined to growers w ho are not m em b ers of t h e Crop Im pr ovem en t Assoc iation. During 1955-56 ins p ecti on s w ere m a d e in 4 cou nt ies on 2,150 acres of cotton.
European Corn Borer
During th e summ er of 1955 th e Europ ean Corn Borel' b ecame a major probl em to growers of pimi ento peppers in th e state of A labama . Large q uantiti es of these peppers were being shippe d int o t his state, and in m any instanc es, in to th e h eart of our pimi ento p e pp er growing area . In a sm uch as this serious pest is now known to occur in this area, and because of t he t hreat imposed by importation of pi mi ento pepper fr uit infest ed with th e European Corn Bo rer, r egul a tions were drawn up restricting the entry of pimiento peppers from areas kn own to b e infested with th e E urop ean Cor n Borel'.
Surv eys were in t ensif ied in Georgia to locate infestation of this p est in this state. During this period surveys w ere mad e in 12 counties of so m e 707 acres of corn. At th e present t ime infestatio n of t h e Europ ean Corn Borel' a re n ow k nown to occ ur in th e fo llowing Georgia counties: Ra bu n , Whitfi eld, Wa lk er, Ch at ooga , Floyd and Polk.
Khapra Beetle
During this period ins pections w ere mad e in Atlanta and Augusta for the Khapra Beetle with negative results. This insect is a serio us pest of sto red gra ins rece ntly fo u nd in this co untry. It is known to occ ur in limited locat ion s in Ca lif ornia, Arizona and New Mexi co . In addition, inspections w ere made of rai lway ca rs locat ed in t his state t hat had carried m aterial inf est ed wi t h K hapra b eetl es. Th ese ins pectio ns were a lso n egative .
Vedalia Beetle Distribution
V edalia be etles are on e of the ma n y be neficial ins ects a nd are particularly important as th ey are parasitic on the cotton ly cushion scale . T h e contro l of this scale ins ect by th e us e of insecticid es is extre me ly diffic ult, so t hes e parasites are r ear ed a nd distributed as a p ub lic service to Georgia nurserymen and cit ize ns on r equ est.
