REMEDIES AND PREVENTIVES. 
The common method of procedure against this insect, and the one 
hitherto generally suggested, is to clip off and burn the withering 
infested tips in the spring as soon as the injury is noted. The fore- 
going life history emphasizes the fact that it is necessary to do this 
very promptly, for the larve remain in these situations a very short 
time, and early in May the larvie will have abandoned their burrows 
in the young shoots to transform, often elsewhere, although sometimes 
pupating in the withered leaves. The presence of dying terminals 
does not always indicate that a larva is necessarily present, since in 
many instances it will have wandered to some other point. With large 
orchards this step would be a very tedious one and with trees of any 
size often impracticable. 
The knowledge of the hibernating habits of this insect indicates a 
more effective method of control, namely, the one already recommended 
by Mr. Craw on the strength of Mr. Ehrhorn’s observations. This is 
in spraying the trees during January or February with kerosene emul- 
sion or resin wash, or some similar oily preparation, which will pene- 
trate the burrows and destroy the young larvie. 
It is possible that something could be accomplished by an arsenical 
spray in the fall, but special care would have to be taken to get it where 
the eggs are apt to be placed. Many of the larve might thus be 
poisoned while eating through the bark preliminary to the construction 
of their hibernating burrows. To effect anything by this course the 
poison must be applied early—that is, before the eggs are deposited— 
and its feasibility will depend somewhat on the conditions of the trees 
and the danger of scalding foliage. 
In the matter of spraying with poisons for this insect a timely sug- 
gestion is made by Mr. Cordley, viz., to spray the trees with paris 
green just when the leaf buds are unfolding, so that the first meal 
taken by the larve in the spring will be a poisonous one. In spraying 
the young tender foliage of the peach, plum, etc., a strength should be 
used not greater than one pound of the poison with an equal amount of 
lime in 200 gallons of water. 
BIBLIOGRAPHY OF THE PRINCIPAL WRITINGS. 
The foliowing bibliography of this insect gives the principal writings 
but omits a number of unimportant references which merely repeat the 
common information relative to the species. Someof the articles cited, 
as will be duly indicated, relate in part at least to a distinct insect, viz, 
the strawberry crown-miner, which seems to be undescribed. 
ZELLER, ©. P.—Isis, 1839, p. 190. 
Contains the original description of the moth. 
CLEMENS, Dr. B.—Proc. Acad. Nat. Sei., Phila., 1860, p. 169. 
Describes the insect as Anarsia pruinella from an adult reared from a larva 
taken crawling on a plum tree.
