On the other hand, these lamps attract many beneficial insects, which 
aid us in destroying the harmful ones, and many hundreds of the 
former are trapped and destroyed. Thus, instead of being a benefit, 
this lamp trapping is a positive injury, and can not be too strongly 
condemned. 
TRAP ROWS OF COTTON.. 
It was often noted that one field of cotton was badly infested, while 
one or more adjoining fields remained free for a long period. This 
fact emphasizes the statement previously made that the weevil spreads 
slowly to new territory once it finds growing cotton to feed upon. It 
further argues the advisability of everyone’s fighting the pest regard- 
less of what his neighbor does. Investigation established the fact that 
the fields infested with weevils so long in advance of the adjoining 
fields were the earliest planted and the first to offer food for the 
weevils emerging from their winter quarters and taking up the search 
for young cotton. In other words, this first cotton formed centers of 
attraction and concentration for the weevils as they appeared. The 
neighbors who planted later escaped the early attacks. 
This suggested the advisability of testing the method of planting a 
few rows of cotton extra early, and of an early maturing kind, so as 
to uniformly trap the emerging hibernating weevils as they came to 
the fields. These few early rows planted some time ahead of the 
main crop serve to concentrate the pest on them. By treating them 
and making war on the pest on these few rows the work is not only 
more effective, but the labor and cost are also immensely reduced. 
Accordingly, in a number of instances trap rows were planted on 
plantations in the manner indicated to test the value of this method. 
The results exceeded expectations. The trap rows were the first to 
produce squares for the weevils, which quite uniformly confined their 
first attack and egg laying to these rows for some time after the main 
crop, which was planted much later, was up and growing nicely. 
Just how long the planting of the main crop should be delayed 
after the trap rows are well started depends largely upon weather 
and local conditions.- Each planter must manage that to suit his 
locality. The special point to be observed is to plant the trap rows as 
early as may be and give them as great a start of the main crop as is 
possible. Generally speaking, make sure that the trap rows are 
attracting the weevils before the rest of the crop is planted. 
In answer to the question, Why not plant the entire crop early? it 
may be stated that there is no objection except that it makes a trap of 
the whole plantation and multiplies the expense of destroying the pest 
over the whole field, whereas the first early warfare against the pest 
might be confined to the trap rows. 
The question may properly be asked, Where should the trap rows 
be planted? According to my observation, the first boll weevils in
