476 INSECT PESTS OF FARM, GARDEN AND ORCHARD 



quarter inch long, rather plump and cylindrical, and tapering 

 at each end. The body is white, but each segment is marked 

 across the back with a broad, tawny yellow band, and numerous 

 short white hairs. When full grown the larva drops to the 

 ground and forms an earthen cell just beneath the surface, in 

 which it transforms to a yellowish pupa, from which the beetle 

 emerges the next spring. Only red raspberries seem to be affected, 

 and some varieties are particularly injured. The insect has been 

 reported as injurious from Minnesota to Massachusetts and in 

 Ontario. 



Control. Inasmuch as the beetles feed freely on the foliage 

 before ovipositing they may be destroyed by spraying the leaves 

 with arsenatc of lead. Mr. Goodwin has shown that where 

 foliage was sprayed with 4 pounds per barrel, that three-fourths 

 of the subsequent injury to the berries by the larvae was prevented 

 by the destruction of the beetles, and the injury to the flower 

 buds was also lessened. Thorough cultivation in the fall close 

 around the bushes will probably destroy many of the pupae by 

 exposing them to winter weather.
