of the stems. The bodies which I took to be the eggs were deposited 
on the leaves on their sides and were fusiform in shape, of a clay- 
yellow color and the surface of each one was longitudinally wrinkled. 
They are well shown in plate 7. On June 16, 1921 I took several of 
the beetles on the common wild elder at Deposit, N. Y. These 
beetles were confined in tumblers with leaves of the elder for a 
day or two until time could be found to care for them. During the 
night of the 18th the beetles deposited several of the fusiform, clay- 
yellow wrinkled eggs in the tumblers identical in shape, size and appear¬ 
ance with those found on the leaves to which reference has already been 
made. On the 19th four more eggs were laid by one of the beetles. I 
did not, however, succeed in getting any of them to hatch. The eggs 
are about 3 mm. long and 1 mm. in diameter. 
It is quite possible that the larvae may be destroyed by the use of 
paradichlorobenzene, applying it in the same manner as it is applied to 
control the peach-tree borer. I am inclined to think, however, that the 
gas might be more effective if the crystals were applied in the spring 
during the latter half of April rather than in the fall. 
RED BUG CONTROL IN SOUTHERN PENNSYLVANIA 
By J. R. Stear, Assistant Entomologist, Penna. Bureau Plant Industry, Harrisburg,Pa . 
Abstract 
The hatching period of the bright red bug, Lygidea mendax, in southern Penn¬ 
sylvania comes so late in the blossom pink stage of nearly all varieties of apples 
that the pink spray is ineffective in control. A comparison of pink with the petal 
fall spray on the York Imperial, a late blooming variety, gave little difference in 
control. Two applications of nicotine gave no additional control. On earlier 
blooming varieties the petal fall spray would prove much more effective. One ap¬ 
plication of nicotine at petal fall is advised. 
The species of red bug considered in this article is known as the false 
or bright red bug. 1 In southern Pennsylvania it is the species respon¬ 
sible, so far as observed for all injury to apples. The dark red bug, 2 
thus far has not been collected or reared from apples at the Chambers- 
burg laboratory. 
The usual recommendation for red bug control, calling for a nicotine 
spray before the blossoms open has been followed in southern Penn¬ 
sylvania with varying results. Considering this, it appeared desirable 
to correlate the hatching of the red bug nymphs with the blossoming of 
several varieties of apples. 
In 1921 and 1922, the writer correlated the first hatching of red bugs 
with the blooming period of several apple varieties, viz., York Imperial,

l Lygidea mendax Reut.
