THE GREEN SOLDIER-BUG. 81 
the bug's attention from the cotton bolls is of practically no economic 
importance. 
DESTRUCTIVENKSS. 
The green soldier-bug has shown itself to be of importance as a 
cotton pest not only owing to its widespread occurrence but also to 
the fluctuations in its numbers, which result in considerable local 
damage from time to time. An instance of this kind has been men- 
tioned by Professor Sanderson." The correspondent referred to, 
Mr. R. L. Taylor, of Help, Bosque County, Tex., has kindly furnished 
additional information concerning his experience with the insect. 
This is of sufficient interest to present in summarized form at this 
place, as it represents the experience of a cotton grower whose obser- 
vations were made and conclusions arrived at independently of 
previous knowledge of the destructive capabilities of the insect. 
The accuracy of Mr. Taylor's observations is sustained by the close 
correspondence between his description of the effects of the green 
soldier-bug's attack and the effects of the attack of the conchuela, 
which has already been considered in detail. He writes that the 
insect was first noticeably abundant in 1901, and it was observed 
that year that many bolls failed to open perfectly; in some instances, 
from as many as 30 bolls on a plant not more than 5 opened and 
produced good lint. The insects were also abundant in 1902 and 
damage to bolls was again noticed. In 1903 the damage was not so 
severe, but much staining of lint was believed to be due to the work of 
the bugs. A local cotton buyer claimed that the condition of the lint 
was due to frost, although Mr. Taylor states positively that there 
had been no frost at the time (October). Whenever the bugs were 
present in numbers it was observed that the cotton was "spotted," 
that is, one, two, or three locks of a boll opened, while the remainder 
in each case failed to open. Shedding of badly damaged bolls was 
also noted in 1902, but this was probably confined mostly to bolls 
less than one-half grown, as was observed in the case of damage by 
the conchuela. 
Bosque County, in which Help is situated, was first infested by 
the boll weevil in 1902, and the first damage to cotton in the county 
was observed in 1903. It should be noted that there is therefore no 
possibility of the confusion of injury by boll weevil attack with that 
of the green soldier-bug.
