being fested as fly hosts by E. T, Fidos. Wichita, Kans., reveals that 
"Hordeum pusillum Nutt., a native grass common to many wheat fields in 
this section, appears to be an important (potential) host of Phytophaga 
destructor Say» Thirty-three and six tenths per cent of the plants in— 
fested with eggs (artificially) produced puparia or grown larvae on this 
grass. The puparia were much cmaller than those grown on wheat, but ap— 
peared to be normal in other respects." 
COTTON INSECTS 
Early oviposition of Pectinophora gossypiella Savnd.—-Reporting 
on the life history of the pink bollworm, W. L. Owen, jr., Presidio, 
Tex., says: "The first oviposition was recorded on April 21, when 135 
eggs were recovered from a lantern globe cage which carried cotton seed— 
lings. The eggs were fertile." 
First eggs of Heliothis obsoleta Fab in Rast Central Texas.—-B. 
W. Dunnam and R. K. Fletcher, College Station, Tex., report that "Al— 
though thousands of host plants were examined during the spring for 
eggs (of the cotton boll worm), none were found until April 8, when 5 
eggs were recorded on 700 alfalfa plants." 
Croton host of cotton fleahoppers.—-Mr. Dunnam and R. W. Moreland 
report: "On April 27 heavy infestations of cotton flea hoppers were ob— 
served in a few cotton fields in which croton and other weeds were pres— 
ent. The croton was in the 2~- and 4-leaf stage and the examination re-—- 
vealed from 1 to 4 hoppers on practically every plant in certain portions 
of these fields. Dock and cudweed were also infested. Moderate in- 
festations of cotton growing in these fields were also observed. A 
few infestations of the small croton growing in the woods were recorded." 
At Tallulah, La., K. P. Ewing and R. L. McGarr found "On April 5, the 
first field nymphs of the season on young croton plants. The largest 
nymph observed was a fourth instar. The first P. seriatus adult of the 
season was found on April 18 on erigeron." 
Record emergence of boll weevils at Tallulah.--G. A. Maloney re— 
ports that "Emergence to April 16 was 4.76 per cent, exceeding all records 
to this date and comparing with the next highest emergence of 3.71 per 
cent in 1927. * * * The first boll weevils in the field were reported by 
farmers from Rockwell County in the northern section during the week end—
