the vines and pupates, hibernation beginning in August, surviving 

 the winter flowage and continuing until the following June or July,^ 

 when the adult emerges. The eggs are usually laid in the calyx cup 

 under the lobes, or on any part of the berry. Spraying with arsenicals 

 has given little success in the control of this species. Studies in flowage 

 treatment have previously been recorded [see this Review, Ser. A, iv,, 

 p. 486, and vi, p. 554]. Eniglaea apkita, Grote (cranberry blossom 

 worm) is a recently discovered cranberry pest in New Jersey, and has 

 not been recorded as a pest from other cranberry sections. Eggs are 

 laid in autumn on litter beneath the vines, the larvae appearing 

 in late May and early June. Feeding is at first confined to the leaves 

 and later the buds are bored into, thus spoiUng them for fruit produc- 

 tion. After feeding throughout the summer, pupation occurs in early 

 September in litter or in an earthen cell just below the surface of the 

 ground. Adults appear in late September and October. As a control 

 for the larvae, a heavy application of calcium arsenite on 30th June 

 was very effective, but proved somewhat dangerous to the vines ; 

 a safer treatment is with 3 lb. lead arsenate paste or 1^ lb. powder to 

 50 U.S. gals, water, with the addition of 2 lb. resin-fish-oil soap. When 

 feasible, much good may result from flooding the bog for one week 

 immediately after picking the crop. If the water is applied in October, 

 when the adults have emerged from the ground and are resting on the 

 vines, the flood will destroy large numbers of them. Autumn flooding 

 probably destroys the pupae also. If reflowage can be applied in 

 June for 48 hours many of the worms will be destroyed. Scudderia 

 texensis, S. & P. (cranberry katydid) ruins a large amount of fruit 

 on the New Jersey bogs in its efforts to obtain the seeds of growing 

 berries. Young katydids first appear on the bogs about mid- June 

 and attain their full size in August, eggs being laid on blades of grasses 

 in September or October, which survive the winter. Flooding the 

 bogs in winter does not kill the eggs, but as these are laid on grasses,, 

 preferably double-seeded millet {Panicum viscidum) or deer grass 

 {Panicmn dichotomum), neither of these grasses should be allowed 

 to grow on the bogs or along the dams. For clearing dams of grasses 

 a form of torch delivering a spray of burning kerosene is found effective. 

 Grasshoppers, particularly Schistocerca aluiacea, Harr., and Melanoplus 

 bivittatus, Say, and crickets destroy many berries. The former 

 oviposit in the stems of sedges, rushes and large grasses, the latter 

 in sandy dams or sandy patches in the bogs. Cleaner culture is 

 desirable on bogs so infested, in some cases complete flooding out 

 lasting two years is necessary, in others holding of the winter 

 flowage until mid- July will destroy many objectionable weeds. The 

 usual grasshopper poison-bait is also useful in the control of these 

 species. 



Vine-attacking insects include Crambus hortuellus, Hb. (cranberry 

 girdler), which has recently been dealt with [see this Review, Ser. A, 

 vi, p. 10] ; Phylloscelis atra. Germ, (toad bug) [see this Review, Ser. A, 

 ii, p. 455] ; Amphiscejya bivitta, Say (vine-hopper) [see this Revieiv, 

 Ser. A, vi, p. 110], and minor stem feeders, including Clastoptera 

 proteus, Fitch (cranberry froghopper), Pseidococcus adonidum, L. 

 (mealy bug) and various scale-insects, such as Aspidiotus ancylus, 

 Putnam, and Lepidosaphes idmi, L.
