THE LESSER PEACH BORER. 45 
a single larva of the lesser peach borer. It has been found at Oden- 
ton and Jessup, Md. (March to May, 1905), and at Fort Valley 
(April, May, July, 1905), and Myrtle, Ga. (March, 1906). 
Bracon mellitor Say is also a rather common parasite of the lesser 
peach borer, and its method of attack is similar, being fatal to full- 
grown larve in their cocoons. After leaving the body of the host 
the parasite larve spin small compact cocoons side by side, which 
completely fill the host cocoon. They pass the winter in this condi- 
tion and emerge the following spring. Thirty-four males and 31 
females of this parasite were reared from two host larve during 
April, 1905. The parasite also attacks the larva of the peach borer 
and has a number of other hosts. It has been found to occur in the 
same localities as the eulophid parasite, but in Georgia, in 1906, 1t was 
rarely met with. It was rather common in Maryland in the spring 
of 1905. A species of Microbracon was also reared from the larva in 
Maryland and Georgia. 
During 1905, at Fort Valley, Ga., Mr. J. H. Beattie, then of this 
Bureau, reared Conura n. sp. (determined by Titus), from the lesser 
peach borer. The parasite emerged May 30 from the pupa. Also in 
May he reared Pimpla annulipes Brullé, from the same stage of the 
host. This is probably the parasite referred to by Bailey (1879). 
Mr. Beattie also reared a species of Campoplex in May, 1905, and 
a species of Mesostenus in May and June, at Fort Valley, from this 
borer, making a total of six hymenopterous parasites, all of which 
were determined by Mr. Titus. 
An undescribed variety of Dorymyrmex pyramicus Roger, as deter- 
mined by Mr. Theodore Pergande, has been observed to attack the 
larva when exposed during “ worming.” This ant is very numerous 
in the peach orchards of Georgia, in the vicinity of Fort Valley, and 
will prey upon any insect which it is able to overcome. Ordinarily 
it is unable to get to this borer. Occasionally, however, it will kill 
recently emerged moths, and any larve which may have been over- 
looked during “ worming,” but which had been exposed. Mr. Titus 
reports this ant as being abundant on peach trees at Monticello, Ga., 
in August, 1905. , 
It is indicated that birds sometimes extract pup from cocoons 
under loose bark, and Bailey (1879) mentions a woodpecker as ex- 
tracting larve from the trunk of a plum tree. 
~The value of the parasites of the lesser peach borer is greater than 
that of its predaceous enemies. 
PREVENTIVES AND REMEDIES. 
From the fact that this insect prefers to attack trees which have 
been injured or diseased, or are old, having wounded or checked bark,
