Control. 



While the caterpillars in their winter cocoons are able to sur- 

 vive ordinary winter submergence of the bogs many may be 

 killed by flowing the bogs for ten days or two weeks directly 

 aft(T picking. The water should tlu^n Ix^ drawn ofl' to allow 

 the vines to ripen. Holding the winter flowage on the bogs 

 till the middle of May is of great value in ccjntrolling the fruit- 

 worm, but as it is likely to reduce the size of the crop it is not 

 advisable to practice it except every third or fourth year. On 

 dry bogs recourse must be had to spraying, although it has not 

 as yet given fully satisfactory results ; 1 pound Paris green 

 and 2 pounds resin fish-oil soap in 50 gallons Bordeaux mixture 

 have been recommended ; the resin fish-oil soap is used as a 

 sticker. 



Many infested berries are picked with the crop and taken to 

 the screen house, where they are screened out before the fruit 

 is sent to market. These screenings should be burned promptly 

 before the caterpillars have time to emerge, and after the pick- 

 ing season is over all cracks and crevices about the screen house 

 should be cleaned out to destroy all the caterpillars that have 



spun up in them.

The Cranberry Katydid 



Scudderia texensis Saussure 



In New Jersey this large, green, broad-winged katydid has 

 sometimes been very destructive to the fruit, the seeds of which 

 they devour. The adult katydid is about 1} inches in length 

 and the female is provided with a flat, sickle-shaped ovipositor 

 by means of which she inserts her flat, slightly kidney-shaped,
