ccn wasps (I. rimac). Mr. Holloway says: "Mr. Jaynes has been sending 
them in cans 5 1/4 by 10 3/4 inches, two cans to a crate. Though sent by 
airplane, reaching us in six days, the shipments have mostly been un— 
satisfactory, the survival being sometimes as low as about 1 per cent. 
It seemed tc make little difference as to whether or not the cans were 
with or without screened cpenings to allow forair. At last Mr. Jaynes sent 
a crate alone, 5 3/8 by 8 3/4 by 10 3/4 inches, without cans, the sides 
being screened and covered with black cloth to reduce the activity of 
the insects. This cage was a great success. Out of 980 wasps sent, 
550, or 56 per cent, reached us ealive," “ 
C. M. Packard and W. B. Noble, West Lafayette, Ind., made a study 
of widespread injury to lawns and golf greens by sod webworms during the 
month of July. "Several species are involved, as shown by our rearings, 
probably Crambus mutabilis Clem., C. trisectus Walk., and C. caliginosel— 
lus Clem., although authentic determinations have not yet been received 
from Washington. Wild birds and chickens have been observed digging up 
and eating the larvae. A dipterous parasite is common but not present in 
controlling numbers." 
The following report on eggs collected by J. ©. Frankenfeld, “an 
the range caterpillar (Hemileuca oliviae Ckll.) territory, in the vicini- 
ty of Tempe, Ariz., is submitted by him: * "Adult Anastatus semiflavidus 
Gahan have been recovered from 10 widely separated localities within the 
range caterpillar infested area. As stated in a previous report (May, 
1931), range caterpillar eggs were collected from 16 localities. Heavi- 
est parasitism occurs along the eastern and southern borders of the New 
Mexico infested area, principally around Clayton and Carrizozo, N. Mex. 
Although occasionally adults are still emerging, it is safe to state that 
not mere than 3 per cent parasitism will be found in any of the 16 locali- 
ties,! 
E. G. Davis, Tempe, Ariz., reports: "The second generation of 
eo ee ee a a er ee 
which causes the greatest damage to corn, was practically controlled this 
year in southern Arizona by the egg parasites — Trichogramma minutum and 
Prospaltella sp. Corn borer eggs were very numerous and the resultant 
larvae would have caused consiSerable damage had it not been for the ac— 
tivity of the egg parasites. A check of the eggs showed that S2 per cent 
had been parasitized, and of these parasitized eggs 50 per cent were by 
Prospaltella sp. and 42 per cent by T. minutaum. Althcugh corn borer eggs 
— ee 
were numerous in the fields, it was difficult te find unparasitized eggs." 
In an effort to determine the effect of the wheat joint worm 
(Harmolita tritici Fitch) upon the yield of wheat, T. R. Chamberlin col- 
lected samples from six preharvest wheat fields in Oregon. The heads were 
then sorted according to whether they came from stems free from infesta-— 
tion or from stems with one two or three infested joints. The results are re- 
ported as follows: "Wheat from one of these samples has been hand 
threshed and weighed. This sample indicates a reduction in yield of 22.2
