ing ground for these and other insects, and do no sort of good. If 
this insect once gains a foothold in the field, it will apparently be 
impossible to dislodge it, except by destroying the plants; and this, 
to be effective, should be done late in summer or early in fall. It 
is probable that even this expedient, however, will be inefficient, if 
the larva breeds in peach trees as well as in the strawberry; and 
unless it were exterminated in both at once, it would be likely soon 
to spread again from one to the other. 
Strawberry growers are earnestly advised to search their fields in 
spring and fall for evidence of the occurrence of this crown miner; 
and especially to look after the wild and runaway plants in fence 
corners and by roadsides. These plants are, at best, superior breed¬ 
ing places for strawberry pests, living, as they do year after year, 
without “rotation;” and it is doubtless careless farming to permit 
them to remain.
