Comb honey section, injured by mining bee-louse larva 
 
 
and the following method of control 
has been    reported  as   satisfactory 
among European beekeepers. 
   To   start the control, prepare a 
sheet of stiff paper the size of the 
interior of the bottom board.  Scatter 
Napthalene Flakes over the sheet and 
insert it on the bottom board. This 
should be done in the evening. The 
fumes from    the Napthalene stupify 
the lice and they are unable to main- 
tain their hold upon the bees. They 
then fall on the sheet of paper, which 
should be removed early in the morn- 
ing and the lice destroyed immediately. 
If allowed to remain until the fumes 
of the Napthalene have disappeared, 
the lice recover and find their way 
back to the bees. 
   This  procedure   is recommended 
only for early spring and in the fall 
of the year, because it does not affect 
the immature forms which, occur dur- 
ing the   summer.   The   Napthalene 
 
 
fumes may irritate the bees slightly, 
but do not produce any detrimental 
after-effects. 
   The bee louse is spread by shifting 
brood combs and may be carried from 
one colony to another by robber bees. 
No preventative measures are known, 
for infection from one yard to an- 
other is easily accomplished by stray 
swarms, and even by robber bees from 
other apiaries as previously indicated. 
 
A  SUGGESTION       FOR    IMPROV- 
   ING CONDITIONS IN THE 
        BEE INDUSTRY IN 
            WISCONSIN 
 
   Since our whole economic condi- 
tion has so badly broken down dur- 
ing the past few years, there would 
seem to be no immediate hope for an 
improvement in prices for farm pro- 
ducts, and particularly such products 
as honey. In times of distress, we turn
