used. To prevent this, spray with Arsenate of lead, using six or 

 seven pounds in tifty gallons of water, as soon as the eggs of either 

 brood begin to hatch, As the time of hatching is often prolonged as 

 already stated, it will usually be found advisable to repeat this spray- 

 ing after a week or ten days for each brood. 



R. Without Water: 



The fact that this insect is not troublesome on dry bogs suggests 

 the following treatment. 



Sand an infested bog heavily and then let it go without jointer /towage 

 for three or four winters, thus alloiving the winter weather and para- 

 sites to work against the insect. At the same tinie, aid these natural 

 agents of control by spraying 7vith Arsenate of lead as reconunended 

 under No. 3 above. Of course, anyone using this method of control 

 will necessarily run some risk of winter killing on the bog.

 Reconiniendations for treatment : 

 A. On bogs with abundant water supply for reflowage : 



1. Examine the bogs carefully from time to ti?ne, from May ist to 

 May i^th. This may be done most conveniently by sweeping the 

 vines with an insect net and counting the worms collected in it. In 

 general if only four or tive caterpillars are collected by fifty sweeps 

 of an ordinary net, when tried on various parts of a bog, the infesta- 

 tion is only slight, and would, better, in most cases, be disregarded 

 unless abundant water supply is available. If, however, every fifty 

 sweeps collects fifteen to twenty or more, the trouble is likely to be 

 serious and treatment is needed. If caterpillars are found in suffic- 

 ient abundance to mahe it advisable, reflow for from twenty-four to 

 thirty-six hours as soon after May i^th as practicable. If the young 

 caterpillars are present in abundance, this will save a great atnount of 

 injury to the buds. Furthermore, less difficulty will be experienced at 

 this time 7oith jvonns which survive the flooding and are 7va shed ashore 

 alive. 



2. If caterpillars are present a few days after the first refiojn, put on 

 the water again for 24 to 3d hojirs. 



3. As far as possible destroy all the 7vorms which are jvashed
