ae 
Mexican bean beetle hibernation in open ficld.--L. W. Brannon, 
Norfolk, Va., reports that "On February 20, examinations were made 
for live adults of the Mexican bean beetle (Epilachna corrupta Muls.) 
in hibernation in an old field of bush lima beans. There was a 
light covering of old bean vines scattered about on the ground. A 
total of 7 live and 3 dead beetles were found under 10 bunches of 
the old vines and stalks. These beetles had survived the minimun 
temperature of 6° F. on February 9. No beetles were found in hiber- 
naticn in pine woods adjoining this open field. On February 21, 15 
examinations were made in a pine woods located 150 yards from a field 
where beans were grown during the fall of 1933. No live or dead 
beetles were found." 
Cigarette beetle prefers tobacco with high sugar content.-- 
W. D. Reed, of the cured-tobacco insects laboratory at Richmond, Va., 
reports that "According to statements of research chemists of the 
tobacco industry, the flue-cured cigarette type of tobacco grow 
in Virginia, the Carolinas, and Georgia, contain from 10 to 25 per- 
cent sugar. This is a reducing suvar, composed »rincipally of 
dextrose. There is a close parallel between the sugar content and 
the grade of flue-cured tobacco, the grades having a high percentage 
of sugar selling for higher prices. Examinations of hogsheads of 
tobacco in storage have shown that cured-tobacco insects prefer the 
sweeter grades of tobacco. The sugar content of imported Turkish 
tobacco ranges from 3 to 19 percent, and the grade containing the 
highest percentage of sugar commandsthe best price. Here, also, 
the insects prefer the sweeter tobaccos, and those grades which are 
high in sugar content are most severely attacked." 
Effects of low temperatures upon the survival of the cigarette 
beetle.--Althvuzh there is a widespread belief anong tobacconists 
that low winter temperatures kill a high »ercentage of the larvae of 
the cigarette beetle (Lasicderma serricorne Fab.) hibernating in 
hogshezds and cases of tobacco, W. D. Reed and A. W. Morrill, Rich- 
mond, report that an examination of samples of nonfumigated fluc- 
cured tobacco collected from 8 hogsheads in a warehouse at Richmond 
in February revealed a survival of 85.9 percent of cigarette beetle 
larvae and 89.1 percent of larvae of the tobacco moth (Ephestia elutella 
Hbn.). A minimum temperature of zero (F.) was recorded in Richmond on 
February 9, and the present winter had been one of the coldest ever 
recorded in the bright--tobacco belt. In special temperature studies 
inside tobacco hogsheads, as compared to outside temperature in 
storage and out-of-doors temperatures, it was shown that the tempera- 
ture inside the hogshead rarely dropped below freezing, except during 
the prevalence of very low storage and out-of-door temperatures.
