close together in one long row, making a long, ragged wound in the 
stem of the plant, as is shown in the figure. If this twig is split 
lengthwise, the light-yellowish or straw-colored eggs will be found 
in the pith. This injury to the raspberry cane is frequently suffi- 
cient to cause it to split and break usually resulting in the death of 
the cane. 
In the early spring, just before the canes begin to put out their 
leaves or even at the time that they are forcing their leaves, these 
injured canes can readily be picked out and cut off. These should 
be burned to destroy the eggs, thus preventing the injury being 
produced a second season. If only a few canes are injured, they 
may be neglected, inasmuch as the young insects and also the 
adults are beneficial. 
The Red-necked Cane Borer is a small beetle about a quarter 
of an inch in length. The wing covers are brownish black, with a 
bronzy luster, while the thorax or “neck” is a coppery red. The 
eggs are laid by the beetle either on the stalk or on the leaf about 
the month of June. The larva which hatches from this egg enters 
the bark at the axle of the leaf, eating around the stem under the 
surface of the bark in a long, spiral tunnel. This girdling of the 
bark produces a gall which appears about August. (See figure.) 
When the larva has girdled the bark, it bores into the stem, and 
lives in the pith. After entering the pith, it usually works up the 
stem for as mucbas six inches above the gall while some cases have 
been noticed where the' distance traveled was much greater than six 
inches. The larva remains in^ these burrows over winter, finally 
transforming into the pllpa about April or May, emerging as an 
adult in May or June. The treatment for this pest is similar to that 
recommended for the Snowy Tree-Cricket. The canes should be 
cut off well below the gall and these stems burned. If there are 
wild raspberries in the vicinity, the pruning of infested canes 
should be extended to these as, otherwise, the beetles emerging 
from these canes would cause injury in the cultivated varieties. It 
is necessary to burn the canes in both cases, merely leaving them 
lying on the ground will be of no benefit, as the insects would be 
able to emerge from these canes. If the careful examination of rasp- 
berry canes is conducted every spring, these two pests can readily 
be controlled.
