Alexander, . Bond, Edwards, Jefferson, and Monroe counties in 
Southern Illinois report great injury from chinch bugs; and \ 
Grenola [Elk?], Franklin, and Panorama [ ?] counties in Kansas; 
Felton [Fulton], and Highland, in Ohio; and Howard in Indiana, 
report considerable injury. "(“Farmers’ Keview Crop Summary for

Under dates of July 2, 9, and 10, and Aug. 5, 1886, the follow¬ 
ing counties in Nebraska report injury to wheat, in three instances 
to oats, and in one to corn: Adams, Clay, Fillmore, Howard, 
Saline, Saunders, and York. Under date of July 16, chinch bugs 
are reported to have destroyed much wheat and oats in Webster 
county, Iowa.

^ Damage by chinch bugs in Iowa in 1887 nearly $25,000,000. 
Summary of life history and habits, and detailed account of obser¬ 
vations at Ames. First damage noted in June, to wheat. On 
corn and Hungarian the middle of July, mostly in adult and pupa 
stages; many adults pairing at this time. Seen taking wing July 
16. Eggs plenty in ground at base of corn stalks, between sheaths, 
etc., July 19, some nearly ready to hatch. July 25 and 27 swarm- 
m g> %i n g with the wind: no pairing noticed. Aug. 3, newly 
hatched bugs plentiful; some on corn, but more on roots and 
stems of foxtail grass. Hungarian, late-planted on sod, suffered 
severely. Weather dry. Aug. 13, bugs were going from the Hun¬ 
garian to corn. As late as Nov. 15 adults were in the fields. Kero¬ 
sene emulsion, five or six per cent., killed the bugs-very, quickly; 
less than four or five per cent, was unsatisfactory. Can hardly 
prove of value except when bugs are massing on corn. Great 
numbers were destroyed by burning stubble and grass. Fire should 
be started in hottest part of day, when greatest numbers will be 
moving. A couple of furrows plowed between grass and corn and 
kept pulverized were effective. To prevent migration from wheat 
to corn, furrows should be plowed several days before migration 
begins, two or three time pulverized, and as soon as there is any 
sign of migration, a weighted trough should be drawn along the 
furrow to reduce the sides to dust, this process to be repeated 
every dry, hot day, by ten o’clock, as long as bugs attempt to 
pass. Experiments were made with pyrethrum and bisulphide of 
carbon, the former proving entirely unsatisfactory and the latter : 
needing further trial. Freventive measures must be the main
