INSECTS IXJIKIOUS TO THE CRAXBERRY. 



115 



worms of the second brood nearly full g^rown upon one 

 bog, while upon anotiier, several miles away, the millers 

 were just laying their eggs for the second brood. 



Water is, and probably always will be, the most ef- 

 fective agent in destroying this insect. Those that have 

 this convenient will find it best, I think, to ti«)w their bogs 

 once or twice between the 10th of May and the Tth of 

 June — that is, if they let off the water eaiiy in the spring. 

 If they keep on the water until the first of June, it would 

 be well to flow two or three times during the month. 



I think it will be difficult to find anything that can be 

 readily applied to destroy these insects in their larva, or 

 worm state. They live so sheltered within tlie leaver that 

 they have drawn together, that it is almost impossible to 

 reach them all, except with w ater. 



When they have spun their cocoons, and have been 

 changed to chrysalides, I think it doubtful if we can reach 

 them with anything. 



I hope that, in time, we shall find some way to entnip 

 the millers and destroy them ; or that something will be 

 found til at will make the vines offensive, and drive them 

 away. 



Knowing that some moths were attracted by a mixture 

 of molasses and water. I experimented with that, and 

 found that it did not atti'act this niiller. I have had no 

 opportunity to test fires, but from what I can learn from 

 others, I think that it is an uncertain remedy, at least. 



Many of these millers might be destroyed by catching 

 thera in a liand-m t of muslin, and crusliing them. On a 

 large bog, this would be tedious ; but on a >mall bog, one 

 or two persons could soon catch most of the millers after 

 a little practice in handling the net, going over the vines 

 about sunset. 



Sawdust, or old rags that have been soaked in kerosene, 

 or something else offensive to insects, if scattered about
