four generations in New Jersey, though three is the normal number. 

 The last generation infests the fruit to a considerable extent in Sep- 

 tember and October. This species can be controlled by holding the 

 winter flowage in one season until 10th May. The wintering moths 

 are then compelled to oviposit on the uplands and the larvae seldom 

 return to the bogs. Lead arsenate, at the strength of 3 to 5 lb. paste 

 to 50 U.S. gals, water, is recom_mended as a spray for newly-hatched 

 larvae. It is suggested also that on dry bogs two sprays should be 

 given at intervals of a week just before new leaves appear at the tips, 

 using 40 per cent, nicotine sulphate (1 : 800) at the rate of 200 U.S. 

 gals, per acre. Gelechia trialbaniaculella, Cham, (red-striped fireworm) 

 is found almost invariably with infestations of P. minvta and is a. 

 dry-bog species. The winter is passed in the larval stage, in a narrow 

 tubular case among badly distorted leaves. Adults emerge from these 

 cases in May, a second generation of adults appearing in July and 

 early August. Bogs that can be covered by winter flowage are not 

 troubled by this moth. Lead arsenate (3^1b. paste to 50 U.S. gals, water)- 

 should control the pest when present on the vines in mid-August. 

 Perrisia (Dasyneura) vaccinii, Smith (cranberry tipworm) has caused_ 

 serious losses in Massachusetts and is becoming very injurious in 

 New Jersey ; in Wisconsin it has been long established and has 

 recently been recorded on the Pacific coast. Winter is passed in the 

 larval stage on the ground and thus winter flowage has little effect 

 on this species. Damage by the larvae is first noticed in May and 

 June, the later generation, occurring in July, being much more 

 injurious. In both instances the topmost leaves are attacked, become 

 cupped and break off. New growth is speedily attacked by the 

 second generation, and few buds are formed, so that no fruit develops 

 on the uprights in the succeeding year. In Massachusetts infestation 

 can be reduced to a minimum by sanding the bog lightly every other 

 year. In New Jersey a much heavier sanding would be required, 

 covering all the litter beneath the vines at least half an inch. Span- 

 worms are sometimes injurious on the vines and can be controlled by 

 lead arsenate or Paris green. Cirphis unijnmcta, Haw. (army worm) 

 and Laphygma frugiperda, S. & A. (fall army- worm) attack cranberry 

 plants in years of unusual abundance ; a prompt reflowage, preferably 

 during cloudy weather, will kill or drive the insects to the shore where 

 they can be destroyed by burning kerosene. Poison-bait or arsenical 

 sprays might be used where reflowage is impossible. Systena frontalis, 

 F. (cranberry flea-beetle) generally attacks new plants, skeletonising 

 the leaves. The beetles first appear in early July and remain throughout 

 the summer. Oviposition occurs in iate July, just below the surface 

 of the ground. These eggs hatch in the following May. Young: 

 plantings sprayed with Bordeaux mixture, with the addition of 3 lb. 

 lead arsenate paste or ]| lb. powder to 50 U.S. gals., are seldom attacked 

 by the beetles. 



Fruit- attacking insects include Mineola vaccinii, Eiley (cranberry 

 fruitworm), which is probably the most troublesome cranberry pest 

 in Massachusetts and Wisconsin, while in New Jersey it is of minor 

 importance. The larva upon hatching burrows into the fruit near 

 the stem, closing the hole with a thin silken web. The seeds are- 

 eaten and some of the pulp, after which the berry is left for another. 

 Upon completing its feeding the larva descends to the sand under
