CEANBERRV INSECT PROBLEMS. 27 



sandy clams iiiul sandy spots m the bogs, but the nieailow grass- 

 hoppers Lay theirs in the steins of sedges, rushes, and hirge grasses. 



A number of growei's contend that although the great injury to the 

 cranberry crop Avrought by the katydid is rightly recognized, too 

 little importance has been laid upon the injuriousness of both the 

 short and the long horned grasshoppers. The contention appears to 

 be well founded. 



Treatment. 



The most effecti\'e way to keep a bog free of grasshoppers is to 

 keep it free of grasses and plants other than cranberry. Weedy bogs 

 are the only ones that suffer appreciable losses from grasshopper feed- 

 ing, and a bog inhabited annually by large numbers of grasshoppers 

 can not become a source of profit until it is free of them. 



Aside from those bogs which are so overspread with undesirable 

 growth that they require a complete drowning out lasting at least 

 two years, there are others in which it would be profitable to hold 

 the winter flowage until mid-July of one season in order to get rid 

 of some of the objectionable weeds. This latter treatment also 

 would be effective in clearing the bog of the grasshoppers and crick- 

 ets for a season or two, and this condition could be made permanent 

 by carrying out methods of better culture. Many of the grassy bogs 

 need better drainage, more ditches, some pruning, and some sanding. 



POTSONEn-BRAN BAIT. 



Very effective results in the killing of grasshopers have been ob- 

 tained in various parts of the United States by broadcasting poisoned- 

 bran bait. One instance is known in New Jersey where this material 

 ]:> roved of great value in destroying grasshoppers on a cranberry 

 1 K)g, and, although its use on bogs has been very limited, it is deserving 

 of further trials. The formula for its preparation is as follows: 

 Wheat bran. 25 pounds; Paris green, 1 pound, or wdiite arsenic, 1 

 pound; lemons or oranges, 6 fruits; low-grade molasses, 2 quarts; 

 water, 3 gallons. 



Mix the bran and poison while dry; add the molasses, the juice 

 of the fruit, and the finely chopped pulp and rind of the fruit to 

 the Avater. Pour the resulting liquid over the poisoned bran and stir 

 well to dampen it thoroughly. This amount of material should be 

 broadcasted over 5 acres of bog, making the application late in the 

 evening, or, preferably, very early in the morning, as at this time the 

 grasshoppers are just beginning to feed. The bait is not attractive 

 to the insects when dry, and two applications should be made, two 

 days apart. In mixing the bran and poison use a spade or other 

 implement, So as to avoid absorption of the poison by the hands and 

 forearms. The damp nuish may be sown with the bare hands.
