VEGETABLE WEEVIL, — The vegetable .weevil, which first attacked tobacco 
plants in' -the seedbeds at Quincy, -Ela., in 1937 * Has continued to infest the • bed- 
each season. The infestation in 194l was of sufficient intensity to require 
control measures on. many of the beds. While the effect of these control reme- 
dies made ' it difficult to determine the potential- .abundance of the pest-on plant 
beds, Observations. in turnip fields and on. other host crops indicated that the 
vegetable weevil was somewhat., more abundant than in • 1940. ■ 
All observations made priOr to 1941 indicated that injuries- caused by the 
vegetable weevil to tobacco plant beds and to newly set plants were confined to 
the feeding of the larvae. The first instance of the adult attacking tobacco 
in the field was observed last April, when, large numbers were found 'destroying 
the outer rows of two newly set .shade-grown, crops,. ' (E, S. Chamberlin, Bureau of 
Entomology and Plant Quarantine, U. S. D. A, ) 
Larvae of the vegetable weevil were observed feeding on tobacco plants 
In plant beds in Florence County, S. C. , on April 10, . about. 1 week later than 
in l'94o. The larvae were also observed feeding on .plant-bed plants . near . 
Mullins, in Marion County, S. C., .during April, which indicates that, the pest 
may bo expected in other tobacco-producing areas of the 'State-, ( IT or man Allen,

TOBACCO ELEA BEETLE, < — At .Oxford, IT, G., in grassland bordering a former 
tobacco field, in the edge, of , woods; and around- old tobacco . stalks in a tobacco 
field, there was a -survival of from 18.5 to .42,-75 percent of tobacco flea, 
beetles in the' hibernation cages. This is approximately- the. sane percentage of 
survival as noted during the 2 preceding year s*. Approximately 100 plant beds, 
located in the' various Tobacco Bolts of Worth Carolina, wore examined. The 
usual method of taking 10 i-sauar e-foot, samples in each bed was followed. The 
average flea beetle infestation per square foot ranged from 0,32 percent in the 
Middle Belt to' 4„9H percent, in' the Eastern Worth Carolina Belt, The data from 
the Border and' Eastern Bolts - were only, slightly greater than for the 1940 
•season>, but -'those from the Middle- ap.d Old Belts were . slightly more tkan 50 -per- 
cent under the : 1940 data. Except in a few isolated, early planted field’s, flea 
beetle infestations were unusually light up to- the middle of July, when they 
were approximately the same as during the; same, period- in 1940, . -Harvest in the 
experimental plots started July 18. A protracted period of drought during 
April, May, and June is 'considered- to- have been, responsible for .the low initial 
populations in the fields. (C. E. Stahl,, Bureau of; Entomology and Plyrf -Quaran-

Cage -studies of the tobacco flea .beetle at- -Florence,. S, ,C for the,194o~4:
