 ly Report U. S. Dept. Agric, May and June, 1875.)

 Kentucky, Indiana, Illinois, Wisconsin, Missouri, and Kansas. 



Thomas, Cyrus. — Chinch Bug. (Prairie Farmer, June 12, 1875.) 



General article on the history and life history of the insect, with 

 notice of remedies and literature. Pass the winter in the winged 

 state; appear in spring between middle of March and first of May, 

 and, at roots of wheat, deposit eggs, which hatch in about two weeks, the 

 bugs reaching maturity in five or six weeks and depositing the second 

 batch of eggs. The insects which hatch from these eggs usually 

 attack corn, and, unless destroyed by climatic influences, live till 

 cold weather and seek winter quarters in which to hibernate. 

 Here they may be destroyed by burning the stalks or rubbish 

 that afford them shelter. Limited areas which cannot be reached 

 by fire may be thoroughly and repeatedly drenched with good 

 effect. Farmers must act in concert. Refers to cases cited by 

 LeBaron, Shimer, and Riley, indicating that cold may kill these 

 insects, and mentions also an instance in which some were thawed 

 from ice in which they had been frozen, and then moved about as 

 in spring. Copious rains at the periods of egg-hatching great 

 check upon multiplication. In a winter following a rainy season 

 they will be reduced to a minimum. Two successive favorable 

 years necessary to their fullest development, and they seldom ap- 

 pear in destructive numbers without having given warning the 

 previous year. 



Cultivator and Country Gentleman, July 1, 1875, v. 40, p. 405. 



A correspondent writes that the "growing of wheat has been 

 almost abandoned in Will Co. because of the chinch bug." 



Cultivator and Country Gentleman, July 8, 1875, v. 40, p. 428. 



Correspondent from Bond Co. says that rain has killed off nearly 

 all the chinch bugs. 



Everest, H. J. -Destroying Chinch Bugs. (Western Rural, July 

 17, 1875.) 



Writes from Dane Co., Wis., of saving corn fields by use of 

 fence boards and tar. Boards set up edgewise; dirt put against 

 their lower edge, and tar poured along the top, it being renewed 

 every five or six days. Holes dug in front of the boards, into 

 which the bugs fell. 



Western Rural, Oct. 23, 1875. Insect Injuries. 



Extract from a summary by the U. S. Department of Agriculture 

 of the injuries done by insects during the present year, which 

 states that the chinch bug "made its power felt in only a few 

 localities."
