A CLASSIFICATION OF INSECT INJURIES TO THE STRAW¬ 
BERRY, WITH SUGGESTIONS OF REMEDIES FOR THEM. 
The study of economic entomology, is primarily and essentially 8 
study of insect injuries to vegetation, and only secondarily, and o 
necessity, a study of the insects themselves. To acquire such e 
knowledge of these injuries as will enable those interested eit er c 
prevent or to remedy them, must be its mam object; an objec 
which can often be attained without a full knowledge of the causa 
which have conspired to produce them. In other words it, is some 
times possible to pass directly from a description of the injury t 
a description of remedial measures, without requiring the perplexej 
farmer or gardener to take into account the technical charactere 
names life history and habits, of the insect causing it. Whereve 
this is possible, the immense advantage is obvious, and shoul 
never be neglected. 
Where as is too often the case, the injurious insects themselves ar 
put to the front as the main objects of study, their injuries bem 
treated merely as incidents in their life history, one must maste 
the whole science of his insect before he can arrive at a remedy fc 
its ravages; and as this requires an amount of skill and specie 
knowledge far beyond the average farmer the practical consequent 
is that his reliable information is usually confined to a very fe 
species so destructive and abundant that their aspect and habits ai 
matters of common knowledge, kept alive by tradition. Even m then 
numerous cases where a simple examination of the insect injury wi 
not point the way at once to the correct remedy, it is often 
necessary to add more than a few words of the simplest descnptic 
of the insect causing it, to enable the ordinary, intelligent observ ; 
to distinguish it from any other attack with which it is likely 
be confounded. 
In short, while the safest and best method is unquestionably 
become as well acquainted as possible with our insect enemies ther 
selves, as well as with the consequences of their attacks, still 
should be borne in mind that much of practical value may be learn 
and applied without any detailed entomological knowledge, provid 
that descriptions of insect injuries are skillfully drawn up ai 
properly classified. 
Furthermore, this grouping and classification of like injuiies, wifi 
out unnecessary reference to the various kinds of insects by win 
they have been produced, has this additional decided advantag 
that the discussion of remedial and preventive measures may 
made to apply to an entire group of injuries, instead ot to separt 
species of insects, as is now the common method.
