Forbes, S. A.—The Chinch-bug in 1882. Field Notes. (Ill. Crop 
Prospects, Circular No. 92, Aug., 1882, p. 77.) 
Reports that the chinch-bug is extremely subject to a minute 
internal parasite, a bacterial species, the spread and multiplication 
of which may account for those sudden disappearances of vast 
numbers of the bugs which have hitherto been attributed to the 
weather. 
Forbes, S. A.—Bacterium a Parasite of the Chinch-bug. (Am. 
Nat., Oct., 1882, v. 16, p. 824.) 
Observation of bacteria in alimentary canal of chinch-bugs 
apparently affected by disease. 
Forbes, S. A—Another Chinch-bug Parasite. (Prairie Farmer, 
Dec. 9, 1882, v. —, p. —.) 
Suggests that white mold of chinch-bugs mentioned in Popenoe’s 
article (see below) is identical with Entomophthora found by Forbes 
destroying chinch-bugs in corn near Jacksonville, Ill., September, 
1882. Reports successful cultivation of Micrococcus insectorum in 
beef broth. Thinks there is a “working possibility” of using 
germs of contagious disease for destruction of insects. Considers 
it quite unlikely that chinch-bugs will appear in destructive num¬ 
bers next year.

(Can. Ent., Feb., 1882, v. 14, p. 88; Rep. Ent. Soc. Ont., 
1882, p. 29.) 
Publishes, with comments, letter from horticulturist giving result 
of experiments with yeast fungus—one apparently successful; oth¬ 
ers without effect. Reports similar variable results from Germany.

Brief mention of Hagen’s views.

Kan. State Board Agr., Sept., 1882; Reprinted in Prairie 
Farmer, Nov. 25, 1882, v. —, p. —.) 
Quotes recent statements of many Iowa farmers that chinch-bugs 
died in large numbers upon corn stalks, ea:h being covered with 
a strong growth of white mold. Suggests connection between this 
observation and that of Shimer in 1867.
