26 FARMKHS BULLETIIs 860. 



The outline of the egg in a bhide of millet may be seen by holding 

 the blade to the light and the egg also can be detected by the slight 

 swelling around the place of insertion. The egg is much flattened, 

 kidney shaped, yellowish brown, and about three-sixteenths of an 

 inch long. The shell is marked with figures ranging from regular 

 hexagons on the flat sides of the egg to ovals and circles on the 

 rounded edges. When placing the egg the female glues it to the 

 inner walls of the grass blade and no portion of it may be seen from 

 the outeide. 



TUEATMENT. 



Formerl}'^ it was inferred that the eggs w^ould not survive winter 

 fiowage, but it has been demonstrated recently that the contrary is 

 the case. Eggs found on a bog in double-seeded millet hatched the 

 following June, after a winter of submergence lasting from De- 

 cember 1 to May 10. 



Since the katydids do not laj^ eggs in cranberr}' leaves but select 

 chiefly the blades of double-seeded millet and deer grass for the pur- 

 pose, neither of these grasses should be allowed to grow either on 

 the bogs or along the clams. For clearing dams of grasses a form of 

 torch delivering a spray of burning kerosene will be found effective. 



GRASSHOPPERS AND CRICKETS. 



Much interest is manifested in grasshoppers and crickets by cran- 

 berry growers and many assertions are heard each year as to the 

 (Quantity of berries that these ins?cts destroy on various bogs. The 

 most recent investigations dealing with these pests have shown that 

 several of the common short-horned grasshoppers can and do eat 

 cranberries on the vines in considerable quantities. Xot only do 

 they finish up berries that have been opened by katydids, but they 

 open up sound berries and eat freely of the pulp. Grasshopper 

 feeding gives to the berry the appearance of having been roughly 

 gouged, while katydid feeding is deeper and leaves the berry more- 

 cleanly hollowed out. 



Feeding tests of the short-horned grasshoppers indicate that two 

 species in particular^ go readily upon the vines and eat berries. 

 These two species are very common throughout the cranberry dis- 

 trict of New Jersey and often have been noted in large numbers on 

 certain grassy and weedy bog's. 



Meadow or long-horned grasshoppers undoubtedly destroy many 

 berries on ill-kept bogs, but there is no evidence to show that crickets 

 will attack berries on the vines, although they have been known to 

 feed on berries on the ground. Crickets lay their eggs aloug the
