FoEBES, S. A. — [Memoranda with regard to the Contagious 

 Diseases of Insects and the possibility of using the virus 

 of the same for economic purposes.] (Abstracts more or 

 less full, in St. Paul and Minneapolis Pioneer Press, Aug. 

 16, 1883; Minnesota Tribune of same date; Canadian En- 

 tomologist, Sept., 1883; and in American Naturalist, Nov., 

 1883, V. 17, p. 1170.) 



Occurrence of bacterial disease of chinch bug reported, and 

 ompared with flacherie or schlaffsncht of silkworm. Apparently 

 caused by a microbe abundantly developed in the alimentary 

 canal. Bugs disappeared rapidly in the field where this disease 

 was recognized, the mortality being chiefly among adults. Disease 

 developed rapidly in chincj;i bugs kept in confinement without food. 

 Bacteria seemed identical with those found in gummy substance 

 under sheaths of corn leaves. Cultivated readily in organic in- 

 fusions.

In Northern New York its work was first discovered in June, 



1882, when a few acres of timothy were badly damaged. In June, 



1883, other fields were infested. Mention of pecuniary losses in 

 Illinois and the United States generally, from ravages of this insect, 

 and also of migratory habit. Brief description given and observa- 

 tions upon the recent attack in New York, of which the range is 

 about eight miles. Invasion threatens to be serious, as, contrary to 

 precedent, the insect has thriven far to the north on one of its most 

 unusual food plants, and multiplied, contrary to all rule, in face of 

 the excessive rains- of the past two seasons. Prompt, earnest, and 

 combined effort against the pest urged, — deep fall plowing; burning, 

 when condition of grass will permit; heavy rolling of infested fields 

 in spring, also of wheat fields just as they are liable to attack; and 

 use of kerosene emulsion as soon as attack is discoverable.
