bugs were sprayed with an atomizer. Six of ten were killed. It is 

 evident that this strength is insufficient for the control of the redbug. 

 To be successful, spraying should be done about the third week in 

 June, before the vines have produced large arms. Most of the nymphs 

 will have hatched and can be reached easily at this time. Later, when 

 the vines become dense and many have slipped down the poles, it is 

 impossible to reach all of the bugs hidden among the mass of leaves. 

 Poles as well as vines should be drenched, as many nymphs take refuge 

 in the cracks and under projecting bark. Because of the agility of the 

 bugs, it is wise to spray a hill from opposite sides at the same time 

 when possible. Winged forms fly before they can be reached by a 

 spray.

AMPHISCEPA BIVITTATA SAY, IN ITS RELATION TO 



CRANBERRY ^ 



By H. B. ScAMMELL, Entomological Assistant, Deciduous Fruit Insect Investigations 



Introduction 



The literature on this Fulgorid is somewhat barren in so far as the 

 subject of its life history is concerned, and the following data are set 

 forth as a contribution dealing chiefly with biological notes made in 

 the course of the cranberry insect investigations being conducted by 

 the Bureau of Entomology in New Jersey. Mr. H. K. Plank assisted 

 the writer during two field seasons and to him he is indebted for making 

 the photographs used in illustrating this paper. 



The insect has been known as the "broad winged leaf-hopper" (1)^ 

 but that appellation scarcely is applicable because, at least on cran- 

 berry, it is not a pest of the foliage but of the woody stems, namely, 

 the runners and uprights. The common name which is here suggested, 

 inasmuch as the sjDecies is associated frequently with cranberry, a 

 cultivated crop, is the cranberry vinehopper. 



Economic Importance

 places in New Jersey and made a statement to the effect that it did
