INSECTS INJURIOUS TO TOBACCO. 217 



the spring, thus depriving the worms of any food during 

 that time. The most successful method yet found for 

 destroying the worms is in the use of a poisoned bran 

 mash. This is composed of forty parts of Avheat-bran, 

 two quarts of cheap molasses, and one ]Dound of Paris 

 green, with enough water to thoroughly moisten the 

 whole. The bran and Paris green should be thoroughly 

 stirred together while dry and the molasses diluted with 

 water, and then poured on and stirred in. The land 

 where the tobacco is to be set out should be prepared 

 several days before. Then dro]) about a tablespoonful of 

 the mash near each hill, doing thi^ from three to five days 

 before the plants are set out, and as near evening as possi- 

 ble. Chickens, etc., should be kept out of the field for 

 several days. The cutworms are attracted by the smell of 

 the molasses and seem to relish the mash, coming out of 

 the ground and making a liberal meal upon it — a meal 

 which almost always proves fatal. This remedy is at once 

 simple and inexpensive and has been found most satisfac- 

 tory by growers who have used it. Any other arsenite 

 could be used instead of Paris green, though the amount 

 used would vary according to the strength of the j^oison.

Prof. W. G. Johnson* has found this species, also known 

 as the Corn-root Web-worm, to be a serious pest to grow- 

 ing tobacco-plants in southern Maryland, where it seems 

 to have been a tobacco-pest for at least fifteen years, and 

 it has also been noted in Delaware.
