that trees sprayed before they blossom, with the arsenites and bordeaux are 

 apt to be pretty fm^ from them. As the insects are periodic in their invasions, 

 often disappearing for a number of years together, it is not possible to fortell 

 just when such a spray will be necessary. Those who apply bordeaux before 

 the buds open, as a regular practice, may find it a paying investment to add a 

 little poison for this insect, the bud-moth, and several other pests. Professor 

 Slingerland also recommends jarring in the same manner as for curculio. The 

 bulletin cited gives much detailed information on the subject.

INSECTS AFFECTING THE RASPBERRY AND BLACKBERRY. 



AFFECTING THE BOOTS. 



Raspberry and Blackberry Crown-borer. {Bembecia marginata.) 



A borer which the writer has seen in the western part of Michigan Is the 

 blackberry crown borer. The adult of this insect is a good sized clear-winged 

 moth, black and yellow in color, with orange front wings. It resembles a very 

 large yellow-jacket in a general way but really is a moth. The larva is pro- 

 vided with feet as in the case of the imported currant-borer, and is to be found 

 about the level of the ground either in the canes above or about the roots, some- 

 times completely girdling the root beneath the surface of the soil. The young 

 are said sometimes to go up into the new growth. 



REMEDIES. 



No better measure is known than that of cutting out the larvte and digging 

 up and burning the dead bushes. Fortunately this insect is not so common as 

 the cane-borers. 



AFFECTING THE CANES. 



The Raspberry and Blackberry Cane-borer. (Oberia bimaculata.) 



The adult Qf the raspberry cane-borer is a slender, cylindrical beetle with long 

 feelers or antennae. The wing-covers and head are black and the prothorax 

 yellow. The eggs are laid in June, in a very characteristic manner, — the new 

 growth of a cane is partially girdled in two places about an inch apart, and
