A es pa 
where the B. funebris received honey-water for food their average length 
of life in May was 29 days for the females and 14.2 days for the males, 
as compared with 18.6 days for the females and 7.9 days for the males in 
July. The mean temperature for May was 71° F. and for July 87° F." 
Effectiveness of grasshorper—bait ingredients.-~-According to J. R. 
Parker, Bozeman, Mont., "Amyl acetate and cane molasses, when used alone 
in poisoned bran largely, increased mortality from 5 to 10 per cent. 
Early in the season amyl acetate used with cane molasses seemed to add 
to the attractiveness of the bait. Cane molasses was about 6 per cent 
better than beet molasses * * * Beet molasses can be used in areas where 
it is produced. There was no significant difference between sodium fluo-— 
Silicate and the arsenics (crude and sodium arsenite). Sodium fluosili- 
cate seemed to act more quickly but the total mortalities were in favor 
of the arsenicals." 
Parasitization of the wheat joint worm in Oregon.—-In November T. R, 
Chamberlin, Forest Grove, Oreg., made an examination of the fall collec-— 
tion of wheat stubble from the sample farm in the Molalla district and 
reports the following condition: Harmolita present, 28.2 per cent; Di- 
tropinotus aureoviridis Cwfd., 20.3 per cent; Eurytoma parva (Girault) 
Phillips, 48.2 per cent; Eupelmus allynii (French) and Eupelminus 
saltator Lind., 1.8 per cent; Calosota metallica Gah., 0.5 per cent; 
undetermined parasites, 1 per cent; total parasitization, 71.8 per cent. 
“ * * examinations showed that 78 other Eurytoma had been destroyed by 
Secondaries as follows: Ditropinotus, 56; E. allynii and E. Saltator, 15; 
Calosota, 4; undetermined parasites, 3. The Original parasitization of 
Eurytoma in the cells as counted in the fall was thus 52.9 per cent. It 
was also found that 118 other Harmolita had been destroyed by Eurytoma 
larvae which had entered more than one cell. The number of Harmolita 
originally present was, therefore, greater by 118 than was indicated by 
the fall count and the total destruction of Harmolita by Eurytoma was 
06.1 per cent and by all parasites was 73.1 per cent. * * * Comparing ~ 
the parasitization in the fall collection from the sample field in 1932 
with that in the corresponding collection in 1931, the total destruction 
of Harmolita by E. parva has increased from 45.2 to 56.1 per cont.) 4aaam 
By the middle of the month most of the H. tritici were still prepupae, 
whereas in 1931 practically all had pupated by the first of the month." 
Oviposition of the wheat sheath joint worm as it affects the plant.— 
W. J. Phillips, Charlottesville, Va., reports that "Of the three species 
of Harmolita infesting wheat, vaginicola, where present, is usually the 
most conspicuous, although it is nearly always the least abundant. * * * 
As H. vaginicola forms galls in the sheath of the upper leaf which con- 
Strict and impede the development of the wheat head, the primary objec— 
tive of our study was to contrast its egg-laying habits with those of He 
tritici, the gall of which is formed in the stem and may occur at any of 
the nodes in the plant, depending on the stage of nodal development at the
