Annual Meetmg at St. JosepJ/. 207 



burrow into the eartli, and each encloses itself in an oval earthen 

 cell and changes to pupa. In the summer the fly appears in twelve 

 or fourteen days thereafter. 



This insect is said to be double brooded in the Eastern States, 

 but with us, I think there must be as many as three broods in the 

 course of the summer, as I observed two broods of larva? after the 

 middle of July. The first brood in May or June escaped my 

 notice. 



The latest brood of larvae hibernate in a dormant state within 

 their earthen cells. 



Like most of the saw fly larva?, this species succumbs to a feM' 

 dustings with wliite Hellebore or with Pyrethrum powder, and also 

 to Paris green in liquid suspension — one teaspoouful of green to 

 two gallons of w^ater. 



Vine growers should be on their guard against this pest, and 

 if possible nip the evil in the bud by thorouglily exterminating the 

 first broods that make their appearance. 



THE PEACH BORER ( ^'Egerta exitiosa, say.) 



Compared with most other fruit trees the peach is naturally 

 short-lived, but there is no doubt that its early decay is much 

 hastened by the attacks of borers, from which it is almost im- 

 possible to protect it. It has several foes of this kind, but the 

 principal one is that named above. This insect, which in its per- 

 fect state is a clear-winged moth much resembling a small wasp, is 

 supposed to confine its work to that part of the tree at or just 

 below the surface of the ground. This habit led to the practice 

 among peach growers of mounding their trees to the height of a 

 foot or more to prevent access of the moth to the particular portion 

 of the trunk which she affected for laying her eggs. This is 

 undoubtedly a remedy to some extent, although it is not safe to 

 mound trees until they are four or five years old, and much damage 

 mav be done in the meantime ; but from observations made this 

 summer I am convinced that the moth is not limited as to locality 

 on the trunk in the placing of her eggs. During the month of 

 August I found indications of this borer on some voung trees, 

 three and four feet above the surface of the ground, and upon the 

 cutting for it I found young larva? in the forks, and none of them 

 lower down than a foot above the surface. If this habit of boring 

 the trunk at any height generally prevails, the mounding system 

 can no longer be depended on for protection, and other measures 

 must be adopted. Soap does not seem to repel the moth, as it does
