that it will adliere in some quantity to the stem end of the young 

 berry, where the worm enters. Any spray, in order to give satisfac- 

 tory results, must be applied two or three times, as the egg-laying 

 and hatching period of the insect is a long one, and the berries are, 

 during this period, constantly increasing in size and number. One 

 spraying would be necessary early in July and another somewhat 

 after the middle of the month. 



D. For all bogs :— 



1. Bury the '•'• screenings ^''' to destroy any worms 7u/iich may be in 

 t/iem. 



2. Clean out all cracks and cre'idccs where worjns may have spun up 

 in the screen house — if this is near the bog — to guard against possible 

 infestation from this source. 



THE FIRE WORM. 



Eudemis vacciiiiana (Pack.) 



This insect is also known as the Vine Worm and the Blackhead 

 Cranberry Worm, the latter being really the best (and least used) 

 name. Its eggs adhere during the winter to the under sides of the 

 leaves, and hatch in the spring, whether the vines have been covered 

 with water or not. Hatching begins late in April or early in May, and 

 apparently continues for at least two weeks. A second brood of 

 worms is produced from the eggs laid by the moths of the first 

 brood. These hatch late in June and early in July. 



It is essential, whatever the bog conditions may be, that measures 

 be taken to destroy the caterpillars of both broods as soon as possi- 

 ble after hatching. Most growers have two weapons at their dis- 

 posal — arsenical poison and water. Some bogs are without water 

 supply, and in such cases arsenical poisoning is the only remedy 

 available. The second brood can only be reached by poisons even 

 where there is plenty of water, as the use of the latter would, in most 

 cases, prove disastrous to vines ,ind crop. It seems probable, how- 

 ever, that if the water be handled rightly, the first brood may be 

 either exterminated altogether, or at least so reduced that the second 

 one will not be worth treating. 



Observations on several bogs strongly indicate that holding the
