Tennessee. L, B. Scott (September 19): Grasshoppers caused serious damage to 
tobacco early in the season, in north-central Tennessee. Damage de- 
creased as season progressed but moderate damage is still being done. 
Damaged more tobacco, in 1940 than all other insects combined. 
Indiana. L. E. Steiner (September 5): Completely defoliated many apple re- 
plants in some orchards in the Vincennes area. 
Ohio. T. H. Parks (September 2l): Became quite abundant during August in half 
a dozen central and several northern Ohio counties. Some defoliation o 
young ^ple trees occurred and in Pickaway Corinty a 15~acre field of 
corn v;as ruined. Hs^brid corn strains show marked difference in suscept: 
bility to injury. 
Michigan, R. Hutson (September 23): Eggs, chiefly Molanoplus mescicanus Sauss.. 
more numerous than last year in Emmet, Cheboygan, Antrim, Charlevoix, 
Presque Isle, Alpena, Crawford, Otsego, and Montmorency Counties, 
Wisconsin, E. L, Chambers (September 26): Damage much less this summer than 
for several years. Adult survey indicates that serious trouble may be 
expected from loss than one-fourth of the area previously having seriouj 
losses. Considerable migration of M, mexicanus during latter part of 
August, Very few eggs laid up to September I5, 
lowo,. H, E, Jaques (September);: Rather sCcarce in northwestern and southeastci 
parts of the Stat$, but rather vridely scattered throughout southwestern 
quarter, 
Missouri. G, D, Jones (September 25)* M, diff erentialis Thos, still oviposit- 
ing in central Missouri, Recent observations in scattered areas in 
southeastern Missouri showed a considerable second-brood 'infestation 
of fourth-instar nymphs of M, bivittatus Say. 
Oklahoma. C, P, Stiles (September 2j); Reported as numerous with some local 
heai'y infestations throughout northeastern Oklahoma. Principal species 
involved is M, different ialis . Second brood H, mexicanus had been hatch- 
ing over a period of several weeks in the northern half of Texas County 
and the northeastern pa,rt of Cimarron County and is dama..ging .early sovn 
wheat. Grasshoppers are now in all instars and from 30 '>^0 40 percent 
a,re' adults, 
F, A. Fenton (September 2S): Riie most serious insect outbreak in the 
State in the past month is that of M, moxicenus in Cimarron and Texas 
Counties, The second generation of this grasshopper is now developing 
and strong flights have been reported coning in from Kansas, Eggs of 
this- species were deposited, throughout the northern, part of Texas County 
end in sneJ.1 areas in Cimarron County in. J'aly, These eggs have hatched 
and the young hoppers arc damaging newly seeded wheat and rather ma.ture 
grain sorghums, A'bout 25 to 50 percent of these grasshoppers had"
