room at a practically constant temperature of approximately 75° F. Ap— 
parently, honey water as food greatly lengthens the life of Anastatus 
semiflavidus; water alone increases length of life materially, put the 
presence of H. oliviae eggs either alone or with water or honey water 
influences the length of life but little, if at all." 
Alfalfa seed chalcis reared from loco weed.--"During the last week 
in May a trip was made by E. E. Russell, of the Tempe, Ariz., laboratory, 
into northern Arizona in company with A. B. Ballantine, of the Univer-— 
Sity of Arizona Extension Service, in order to make a survey of the in- 
sect life attacking the loco weed. It was found that the species of loco 
of greatest concern to the ranchers in the area visited is what is spoken 
of as blue loco (Astragalus diphysus). Large seed pods, roots, and 
stems were collected from the localities visited. * * * 4 species of 
lepidopterous larvae from roots and stems; 2 species of Coleoptera; 
and 5 species of Hymenoptera, including Bruchophagus funebris How. and 
two of its most important parasites." 
R. L. Shotwell, Bozeman, Mont., "Small grain fields, especially barley 
fields of last year when stubbled into crop this spring, yielded an abun- 
dance of hoppers over the whole field. In this same type of field when 
well worked last fall and sowed to winter wheat, there were no hoppers 
this spring, indicating that cultural methods applied in the fall are a 
check to infestation. Corn land is worked in the spring on grain stub— 
ble left over the winter. These stubble fields produced abundance of 
hoppers this spring. When listed to corn, many were destroyed and the 
rest migrated to the edges of the field, where they were easily poisoned." 
COTTON INSECTS 
Baled alfalfa hay may carry pink bollworm.--"An experiment was 
planned," report D. A. Isler, and A. J. Chapman, Presidio, Tex., "to study 
the possibility of cotton bolls being raked up and baled with the hay 
when an old cotton field is planted to alfalfa, and to determine the 
rate of mortality and length of time long-cycle larvae remain in old 
bolis in an alfalfa field. On February 8 and 9 several bags of bolls, 
with an approximate infestation of 1.135 worms per boll, were distributed 
over about one-quarter acre of soil. The plot was then disk harrowed, 
alfalfa seed sown and covered by the use of a peg-—tooth harrow, and an 
irrigation given. On May 3 an examination of 100 bolls taken from the 
surface of the soil showed 87 live larvae. The alfalfa was cut on May 4 
and raked on May 5. From 2,125 pounds of hay, 291 bolis that had been 
raked up with the hay were collected. The examination of these bolls 
showed 97 live larvae. From these observations it is evident that there 
is considerable danger of reinfestation from old cotton fields seeded to 
alfalfa." The studies to determine larval survival in such bales have 
not been completed but indicate survival for several weeks.
