Since the catch increases with the suitability of the media for yeast de- 
velopment, the value of the solution as a bait depends very considerably 
upon the rate of its fermentation." 
Oriental parasites of corn borer shipped.-C. A. Clark reports from 
Kobe, Japan, that "Shipments of overwintering larvae (of parasites of the 
European corn borer) during January totaled 240,000 * * * The tachinid 
Ceromasia lepida Meig. and the ichneumonid Cremastus hymeniae Vier. should 
be obtained in numbers from these larvae. Kokubu section, in Kagoshima 
Ken, Kyushu Island, Japan, is a new section for large-scale collections. 
Larvae from this area will give the very desirable parasite C. hymeniae 
in much larger numbers than we have ever been able to secure before. Over 
100 fairly well-trained collectors are now available here and collections 
average 8,000 to 10,000 larvae per day. Kokubu section is about 15 miles 
from Kagoshima (City) and consists of a narrow valley about 10 miles long, 
with Kokubu as the principal town." 

Sorghum midge and corn earworm emerge early.-E. V. Walter and Lee 
Seaton, San Antonio, Tex., report their observations on Contarinia sorghi- 
cola Coq.: "The excessively warm, damp weather has apparently been quite fa- 
vorable to the midge so far. One adult female emerged in our emergence 
cage on February 20. On the same day Johnson grass was found in bloom. 
This is our earliest record of emergence and also of blooming Johnson 
grass. Part of a plot of grain sorghum was cut and bound in bundles and 
placed in a shock last November. The remainder of the plot was left stand- 
ing to get a comparison of the overwintering of the midge and parasites 
in the two treatments. One hundred apparently infested spikelets were 
taken from each of 10 heads from each source on February 10, thus giving 
1,000 spikelets from each source. These were dissected by Mr. Seaton * * * 
it seems that there was practically no difference in the ability of the 
midge or its parasites to successfully pass the winter in either of these 
treatments when the winter is as mild as the present one has been." George 
W. Barber, of the Savannah, Ga., sublaboratory, states that "On February 19 
a corn earworm moth (Heliothis obsoleta Fab.) emerged from hibernation, the 
larva having entered the soil between August 20 and 24, 1931. No other 
emergence from hibernation has been observed. In 1931 the earliest emerg— 
ing moth was recorded on May 1." 
New joint worm has three generations.-F. F. Dicke, engaged in joint- 
worm investigations at Charlottesville, Va., reports that "A new species 
of Harmolita was found infesting Reed canary grass (Phalaris arundinacea 
L.) at Fairfield, Va. Observations on the life cycle of the species 
during the past year revealed three complete generations. This is the 
first species of Harmolita on record having more than two generations 
annually. It was heavily parasitized by Syntomaspis lazulella Ashn. 
and moderately by Eupelmus_allynii (French) and a species of Merisus."
