Pia es 
Cremastus hymeniae Vier. have been found to havea life cycle of about 26 days 
at Kobe, Japan, in July and August. About nine days are spent in the cocoon 
stage. Adults do not usually attack free-crawling larvae, but hunt actively 
for young larvae which have made shallow holes in the host plant. Corn- 
borer larvae 6 to 10 days old (second-instar) are successfully parasitized 
by this species. The adults can be kept alive in the laboratory for a con— 
Siderable length of time. Some adults kept at the Kobe laboratory had an 
average length of life of 64 2/3 days. These were given plenty of fresh water 
daily on pieces of cotton and also some in the form of a fine mist.. Lump 
sugar was also provided. The temperature in the laboratory was usually 
over 80° F. and often above 90° F." 
Of introduced parasites of the European corn borer, summer collec— 
tions made in the Eastern area by R. A. Biron, Arlington, Mass., "show 
Inareolata punctoria Rom, doing the best work, with Masicera senilis Meig. 
nearly as effective. Both together make up over three—quarters of the para— 
sites appearing in collections from 27 representative towns. Six of these 
towns run over 30 per cent parasitism, exclusive of the egg parasite. Tab— 
ulations are too bulky to offer but the dispersion records and rise of par- 
asitism from these 27 towns are gratifying. * * * Studies under cover of 
the parasite abundance per acre indicated a variation from approximately 
5,000 per acre to 10,000." It is pointed out, however, that "a careful check— 
up Of parasite cocoons and puparia indicated nearly twice as many parasites 
per acre as the figures offered in this report." 
According to H. H. Walkden, of the Wichita, Kans., laboratory, "The 
bait-trap record of emergence and flight of moths of cutworms and related 
species injurious to cereal and forage crops showed the occurrence of a 
heavy flight of Heliothis obsoleta Fab. beginning September 25. * * * The 
flight of adults of the corn earworm was so great that hordes of them set— 
tled down in the business district of the city, attracting general ae 
tion and causing considerable annoyance." 
G. W. Barber, of the Savannah, Ga., sublaboratory, states that "the 
total deficiency in rainfall for the year in the location of our station 
is about 20 inches, with the result that the soil during this month has 
been completely dry for the first few inches and is almost dry toa depth 
of at least 4 or 5 feet, much below the line where water is usually found 
by digging. This has appeared to have certain important effects on the 
soil habits of the ear worm. Larvae of the corn ear worm which entered 
the soil during the period August 20 to 25 dug much deeper as a rule than 
ft have ever observed heretofore under any conditions. Some of them dug so 
deeply that the pupae were found up to 10.4 inches below the surface, while 
depths of 6, 7, 8, and 9 inches were common. Most of these pupae hiber-— 
nated, as a result of these unusual depths." 
"Apanteles diatraeae Mues., the larval parasite of the southwestern 
corn borer (Diatraea grandiosella ‘Dyar), has been very active and effective 
during September," according to E. G. Davis, of Tucson, Ariz. "Adults 
have been numerous in green corn plantings and by the end of the month they 
had parasitized over 80 per cent of the third-generation corn—borer larvae. 
This parasite was still active at the end of the month, although there 
were few corn-borer larvae exposed enough to be attacked."
