THE AMERICAN ENTOMOLOGIST. 



deposit their eggs on the plauts, from which eggs 

 in due time, liatches a second brood of worms. 

 These last come to their growth towards the end 

 of September, and, changing to pupse, pass the 

 winter in that state.* 



We first heard of this leaf-roller in the summer 

 of 1866, when it did considerable damage at Val- 

 l)araiso, Indiana, and we were informed by Mr. 

 ]Sr. R. Strong, of that place, that in 1867 they 

 continued their depredations with him, and des- 

 troyed 10 acres so completely as not to leave 

 plants enough to set half an acre, and that in 

 consequence of this little pest in conjunction 

 with the "VVhitc-grub, he has had to abandon 

 Stra^vberry culture. 



When we met the ad interim committee of the 

 Illinois State Horticultural Society at Lacon, in 

 the beginning of July, 1868, we received from 

 these gentlemen a quantity of infested straw- 

 berry leaves, from which in the course of the 

 next two or three weeks we bred many of the 

 moths. These specimens had been collected at 

 Mr. Bubaugh's place, near Princeton, Illinois, 

 where they were said to be very abundant, and 

 to have completely destroyed one strawberry 

 patch containing several acres. 



Subsequently wo recoivedanother lot of speci- 

 mens fromMr.W. K. Luknis, of Sterling, "White- 

 side Co., 111., Willi the Iblluwiiig remarks upon 

 this very important subject : 



"Where these insects are thick I would never 

 think of raising strawberries. It is strange that 

 I have not noticed any of them work upon this 

 side the river ; while on the south side for a mile 

 up and down they are ruining the crops of ber- 

 ries. Removing the plants does not take with 

 them the moth nor the eggs, so far as has been

tirely destroyed by this insect, though it amoun- 

 ted in all to two or three acres. I hear of a great 

 many men in other places having their crops 

 burnt up with the sun, and have no doubt that 

 it was this leaf-roller, and not the sun, that was 

 the real author of the damage. As for myself, 

 I have on this account entirely quit the business 

 of growing strawberries." 



The only modes of fighting this new and very 

 destructive foe of the Strawberrj— which how- 

 ever seems to be confined to northerly regions — 

 are, 1st, to plough up either in the spring or in 

 (he fall, such patches as are badly infested by it, 

 by which means the pupa3 will probably be 

 destroyed; and 2nd, not to procure any plants 

 from an infested region, so as to run the risk of 

 introducing the plague upon your own farm.
