Where water is not available for floating the bugs off, a method 

 of spraying worked ont on Long Island as reported in Bulletin 

 No. 377 of the New York Agricultural Experiment Station, may be 

 tried. Heavy growth of vines must be mowed at the usual season 

 for cutting and the spray applied between xVugust 1 and 15, using 

 soap solution, 1 pound to 7 gallons, and applying it at the rate of 

 200 gallons per acre. Two apjilications should be given.

Perhaps the most frequently encountered of the lesser pests of the 

 woody parts of the cranberry is the cranberry vinehopper, Avhich 

 almost invariably is found where the vines have been weakened by 

 some other agency. Adult bugs (fig. 31) are usually green, rarely 

 pink, with large wings, giving them a flat-sided appearance, and are 

 about one-fourth of an inch in length. They appear in July and 

 August, and in late summer deposit their eggs in slits made with 

 a sawlike ovipositor in live, woody stems (fig. 3'2) and, as frequently, 

 in dry, dead pieces of cran- 

 berry wood on the ground. 

 The eggs survive Avinter 

 flowage and hatch in late 

 June, Avhen a succession of 

 whitish nymphs, or young, 

 bearing cottony secretions 

 of wax a p p ear. The 

 nymphs are active jump- 

 ers, and the adults have 

 the power of flying as well 

 as jumping. Food is ob- 

 tained by sucking the juices 

 from uprights and runners. 



The bugs could be re- 

 moved by flooding in late 

 July,, but as a general rule 

 they will need no treatment 

 and will not infest a bog- 

 in large numbers if the 

 vines are kept in a healthy, 



productive condition. J^"-- ^l- — Cranberry vinehopper : Adults on cran-
