 The female cricket deposits her eggs in the ten- 

 der, growing canes of raspberries, blackberries, 

 and grapes, and the twigs of maple, willow, catalpa, 

 and several other species of trees. 

 The injury thus done often causes the 

 raspberries to die beyond the punc- 

 tures, or else the damaged canes 

 are broken off during the winter.

 burning during foil or winter the

Other Raspberry and Blackberry Insects. 



Raspberries and blackberries are subject to attack 

 by various insects besides those discussed in the 

 foregoing pages. Certain galls are sometimes found 

 upon the roots or stems, due when on the roots usu- 

 ally to the Raspberry-root Gall-fly (Rhodites radicum), 

 and when on the canes to the Red-necked Agrilus 

 (Agrilus ruficollis), or to the Blackberry Gall-fly 

 (Diastrophus nebulosus). The foliage is sometimes 

 eaten by various caterpillars or beetles, and the 

 fruit is occasionally infested by the Flea-like Negro- 

 bug, or the Raspberry Span-worm (Synchlora rubivo- 

 raria). But these various insects as a rule only do 

 an incidental injury, and are rarely sufficiently 

 numerous to require special remedial treatment.
