INSECTS INJURIOUS TO THE STRAWBERRY. 
The May Beetle.— With the increasing attention paid to the 
culture of the strawberry, it has been found that several insects 
not before suspected to be inclined to feed on this plant, now 
habitually frequent it. Of these perhaps the most injurious is the 
strawberry saw-fly, which in this state, but more especially the 
western states, as in Illinois, does in some cases the most griev- 
ous damage. Then a few moths which have been known to feed 
on fruit-trees, the currant, etc., have transferred their affections 
to the strawberry ; such are the apple-leaf-roller or Tortriw, the 
saffron measuring-moth (Angerona crocataria), and several other 
caterpillars found in the western states, and described in the ento- 
mological reports of Messrs. Walsh and Riley, and also in 
‘“Harris’s Treatise on the Injurious Insects” of this state, and the 
reporter’s ‘Guide to the Study of Insects.” 
Next however in importance to the strawberry saw-fly (Emphy- 
tus maculatus), is one of the most common and familar of all 
these insects which everywhere force their attention upon u: 
This is the common May beetle, June beetle or “dor bug,” ae 
American representative in its abundance and injurious qualities 
of the European cockchafer. 
Dr. Harris has given a brief sketch of its habits and transfor- 
mations in his “Treatise,” and referred to the injury the grub, 
sometimes called ‘“ white-worm,” does to the roots of grass, re- 
marking that “in many places the turf may be turned up like a 
carpet in consequence of the destruction of the roots.” He how- 
ever does not say that it attacks the strawberry-roots, which it 
has for several years been known to do in gardens about Salem. 
My attention was especially called to its ravages by Mr. D. M. 
Balch, of Salem, who has lost many strawberry-plants by the 
white grub. It seemed evident that they were introduced in the 
manure placed around the roots, as during July and late in sum- 
mer, a manure-heap near by swarmed with the well-known white 
grubs, in various stages of development, some apparently in the 
second year and others in the third year’s growth. They eat 
the main roots of the plant, thus destroying one plant after an-
