FRUIT INSECTS 



till the caterpillars are larger, many of them will be washed 

 ashore alive and resume their destructive work when the water is 

 drawn off. In some cases where water is not available for more 

 than one reflow it is advisable to hold the winter flowage on 

 the bogs till about the middle of May, thus preventing either 

 the deposition or hatching of the eggs.

The Cranberry Fulgorid 



Phylloscelis atra Germar 



Cranberry vines in the bogs of Long Island are occasionally 

 injured by a small, broad-bodied, nearly black, jumping in- 

 sect (Figs. 392 and 393) which in feeding, 

 punctures the vines, causing the leaves to turn 

 brown. The fruit does not mature properly 

 but shrivels and drops prematurely (Fig. 395). 

 The young insects first become noticeable in 

 the bogs about the time of blossoming. They 

 feed close to the ground under the protection 

 of the vines. They are very active when dis- 

 turbed and difficult to catch. They do not 

 become mature until the last of August and 

 in September. The adults live for a consider- 

 b^ry able time but die off gradually at the approach 

 of cold weather. The egg measures .8 mm. 

 in length and is shown in Figure 394. 

 Control. 



Experiments on Long Island would indicate that the young 

 nymphs can be killed by a thorough application of " Black
