THE SUGAR MAPLE BORER 
T HE most destructive insect of the Sugar 
Maple in the northeastern states is a borer 
which attacks healthy, vigorous trees. It works 
just under the bark in the sapwood, making a 
wide tunnel which prevents the flow of sap. 
The egg of this grub is laid during the summer 
by a beautiful black beetle, having brilliant yellow 
markings. It is about an inch long. The eggs 
are laid just under the bark and by September 
they have hatched and the grub grown to some- 
thing like half an inch long. It spends the winter 
in this condition and continues to feed during the 
following year until it is about sixteen months 
old. It is then about two inches long. This 
grub is white, and footless. It makes a bur- 
row a half inch wide and it is not uncommon 
to find that one of them has tunnelled for eighteen 
inches through the sapwood or just under the 
bark. As they usually go diagonally upward 
around the trunk, it means the cutting off of a 
considerable portion of the sap. 
The grubs usually infest the lower portion 
of the trunk of the iree and the crotches. When 
they work in a crotch, the branch is generally 
killed. This is often the cause of a dead branch 
in an otherwise perfectly healthy Sugar Maple. 
When the grub is working in the trunk of a 
tree, the damage is conspicuous, for it causes 
a ridge over the channel, the bark of which 
is slightly broken. Where several of these 
borers occur in the same tree, it is a matter 
of only a few years before they will completely 
girdle the tree, killing it. 
When it comes time for the grub to change 
into a chrysalis, it starts boring inward toward 
the heart of the tree, and then upward for some 
distance, following the grain of the wood. Here 
the balance of the life of the insect is spent, 
changing from grub to pupae and in spring from 
pupae to beetle, when it emerges, by chewing 
its way out, making an oblong hole, just large 
enough to crawl through. 
To get rid of this pest, one should follow 
the burrow with a strong wire, killing the grub 
by piercing it. Should this method not be satis- 
factory, the burrow can be opened up here and 
there with a knife, and a wire used to clean the 
intervals; it is not wise to cut the entire burrow 
as it may permanently injure the tree. Having 
removed the borer, fill the burrow with cement, 
grafting wax, or similar material to protect the 
wood from the weather. Look for these borers 
each spring and fall, and if the ridges on the 
trunks are not apparent, look for the frass — the 
fine sawdust-like borings, that are pushed from 
the tunnel, in the crotches as well as on the trunk. 
Painting the trunks of the Sugar Maples with 
lime sulphur wash or a carbolic soap wash, in 
early summer, will in most cases prevent the 
laying of eggs by the adult.

WHEN NOT TO CULTIVATE 
I N THE perennial border where uninterrupted 
vegetation is the desideratum, it is unques- 
tionably defeating this purpose to keep up sur- 
face tillage constantly. For a time this is of 
course desirable — that is, until the perennials 
are well established, vigorous plants — but after 
this simply pull out weeds and let the surface 
of the ground alone.
