mpusa aphidis successfully grown on media.=-Le P. Rockwood, Forest 
Grove, Orege, reports that Einnpusa aphidis Hoffman, the fungus that caused 
an epidemic of disease among pea aphids (Tllinoia pisi Kalt.) and checked 
the alarming outbreak of aphids on vetches and field peas in the Willamette 
Valley in April of this year, was successfully grown on a medium consistirg 
of egg and vetch infusion, beaten up together, and also on salmone Pure 
cultures were obtained from 4 out of 24 original specimens. Aseptic condi+ 
tions of collection of the original material in the field appeared to be a 
prime factor in getting pure cultures. This adds one more species of 
Entomophthoraceae to the three others that have been recorded as success- 
fully grown by American workers--Entomophthora pseudococci Speare, by Dre 
Ae T. Speare in Hawaii, and Entomophthora sphaerosperma Frese and Empusa 
Spe, by Dre Wme He Sawyer, Jr., of Bates College. One other species has 
been grown in Europee 
Wheat injured by Sphenophorus confluens Chit.e--T. R. Chamberlin, 
Forest Grove, Oreg.e, reports that on May lo a field of winter wheat near 
Beaverton, Orege, was found to be heavily infested by this weevile Ovi 
position was taking place in the wheat stems and small larvae were commone 
Two samples from the field showed the following conditions: 
May 16 ~ Stems containing larvae or eggs ----------- 28.4 percent 
Stems containing vacated larval tunnels ---_27.43 percent 
Total stems damaged --~--~----------------- 55-7 percent 
Uninfested (some showing feeding punctures 
of adults)----------~--------------------- 44.3 percent

es were usually found in the center of the stem close to the ground in the 
joints directly above or below the adventitious roots. As the stem tends 
to be more or less solid in this region, the eggs may be placed in sperical 
pockets excavated by the adult or in tumels. Sometimes the ege was found 
in a tunnel or hollow-portion of the stem 4 or 5mm distant from the ovi-~ 
position punctures Considerable injury was done the stem by small larvae 
of the first or second stage, tunnels almost 2 inches long and filled with 
frass and having side pockets sometimes being made by a single larvae 
Several stems practically severed by larvae have been found. As the 
species is a large one doubtless many stems could be destroyed by a single 
larva before it reached full growth and, unless there is considerable more 
tality among the small larvae, there seems little chance for the wheat grow+ 
ing in fielde
