 late crop, — plowing or burning stubble immediately after harvest, 

 etc." We must rely on no single measure, but "fight all along the 

 line." Regards as especially valuable in the presence of an out- 

 break, burning in fall and spring, the intelligent use of fer- 

 tilizers, limiting the acreage of crops especially liable to iiijury, 

 the use of lures, fencing with coal-tar mixture, and the use of 

 the kerosene emulsion on corn when it is invaded from the edge.

Infested wheat plots plowed under to the depth of eight inches 

 May 9 and 10 and sJiortltf afterwards harrowed and repeatedl}^ 

 rolled. Notwithstanding this thorough treatment "an enormous 

 brood of young bugs hatched, a large proportion, apparently, reach- 

 ing the surface and passing directly to the adjacent crops, which 

 received great damage from them." This brood did the only 

 noticeable damage that occurred on the College farm b}^ chinch 

 bugs, thougli they were numerous and voracious.

The two diseases that were apparently efficient in suppressing 

 the chinch-bug outbreak of 1882 (described in Kept. State Ent. 111. 

 1882) have not since, until this season, been distinctly recognized. 

 Now, however, chinch bugs in Southern Illinois are being rapidly 

 destroyed by them and by a third disease not hitherto recognized, 

 due to a Botrytis. One of the first-mentioned diseases is caused 

 by an Entomophthora, the other is due to a microbe ( Micrococcus 

 insecloriun,'h\iYYi\\) principally developed in the alimentary canal, 

 and is freely cultivable by the processes usual in bacterial in- 

 vestigation. Both the Botrytis and the Entomophthora finally 

 imbed the insect in a white fungus. The former has been much 

 the more abundant and destructive in Illinois, thougli apparently 

 less so at present than the bacterial form. It seems likely that 

 these diseases will soon suppress an outbreak which, in view of 

 its continuity and destructiveness, probably has no parallel in 

 the history of this insect.

 the Chinch Bug. (Quoted from Colman's Rural World.) 



When you sow wheat in the fall, leave a strip fifteen or 

 twenty feet all around the field, sowing it with millet the follow- 

 ing spring. At harvest the bugs will settle in the millet; then 

 early in the morning, while the dew is on, plow them under and 

 drag and roll the ground thoroughly. The following method for corn 

 is equally effective. With an iron rod and cotton cloth make a swab 

 and saturate with coal oil; then set it on fire, and walking between 

 the rows dash the flames alternately on each side about the stalks, 

 near the ground, while the dew is on. "If there is wind, go against 

 it so that the heat may not precede the flame and scare the bugs 

 oat of its reach; if it is calm, walk rapidly so that the heat will
