120 INJURIOUS INSECTS 



small grain is found about harvest-time to be so badly 

 shrunken up by the bug as not to be worth cutting, the 

 owner ought always to set fire to it and burn it up along 

 with its ill-savored inhabitants. Thus, not only will 

 the insect be prevented from migrating to the adjacent 

 corn-fields, but its future multiplication wiU be consid- 

 erably checked. 



A very simple, cheap, and easy method of prevention 

 was recommended by Mr. Wilson Phelps, of Crete, Illi- 

 nois. It may very probably be eifectual when the bugs 

 are not too numerous, and certainly can do no harm: 



With twelve bushels of spring wheat, mix one bushel 

 of winter rye, and sow in the usual manner. The rye not 

 heading out, but spreading out close to the ground, the 

 bugs will content themselves with eating it until the 

 wheat is too far advanced to be injured by them. There 

 will of course be no danger of the winter rye mixing with 

 the spring wheat. 



THE HESSIAN FLY. 

 {Ceddomyia destructor, Say.) 



A most complete account of this insect is to be found 

 in BuUetin No. 4, of the U. S. Entomological Commis- 

 sion, by Prof. A. S. Packard, of which the following is 

 a brief abstract : 



1. There are two broods of the fly, the first laying their 

 eG;,2:s on the leaves of the young wheat from early April 

 till the end of May, the time varying with the latitude 

 and weather; the second brood appearing during August 

 and September, and laying about thirty eggs on the leaves 

 of the young winter wheat. 



3. The eggs hatch in about four days after thev are 

 laid; several of the maggots or larvro make their way 

 down to the sheathing liuse of the leaf and remain be- 

 tween the base of the leaves and the stem, near the roots.
