Athens, Ohio, and Las Cruces, N. Mex., indicates that the establishment 
of the species for the current season is assured. The abundance of the 
parasite at Columbus and Athens indicates that conditions here are very 
Satisfactory, at least late in the summer. If the fly can withstand the 
northern winter, it is believed that the introduction will be very suc— 
cessful. While no collections were made in Georgia, Alabama, or Kentucky, 
it is felt certain that the fly has become established there, at least in 
the latter two places, for conditions in Alabama and Kentucky were very © 
favorable for it. At both latter places all stages of the bean beetle 
were present and favorable weather continued for many weeks after liber-— 
ation. More flies were liberated at Birmingham, Ala., than at any other 
place. While the bean beetle infestation was not all that might be hoped 
for it at Las Cruces, N. Mex., the climatic conditions there would appear 
to be more favorable than at any other place in the United States where 
the bean beetle occurs in abundance." 
L. W. Brannon, Norfolk, Va., is conducting a study of the life his- 
tory and habits of the sweetpotato leaf beetle (Typophorus viridicyansus 
Crotch), about which there is little known, although it has been observed 
to attack sweetpotatoes for many years in certain sections of the South. 
He says: "It is apparent * * * that the insect will pass the winter in 
the larval stage and that only one generation develops during the year. 
Full-grown larvae were found feeding inside potatoes during the first 
part of the month, and in the same cages where these observations were 
made numerous larvae were found in the soil beneath the surface. Notes 
have been kept of larvae which have been observed in cells at the bottom 
of glass jars used in rearing. The majority of the full grown larvae 
have been observed in cells in the jars for a month or more in a quiescent 
state." 
E. W. Jones, of the soil insects laboratory at Walla Walla, Wash., 
submits data for October on the hibernation depths of larvae and adults 
of Pheletes californicus Mann. and P. canus Lec. Ina field containing a 
mixed stand of the two species 100 per cent of the larvae were found in 
the first foot of soil, and 72 per cent of the larvae and 89 per cent 
of the adults were hibernating at 5 to 9 inches. In a pure stand of P. 
Walitornicus 75° per cent of the larvae and 66 per cent of the adults 
were found hibernating at 3 to 9 inches. In a pure stand of P. canus 
64 per cent of the larvae were found at 9 to 15 inches, and 77 per cent 
of the adults were found at depths of 3 to 9 inches. 
Feeding experiments with the wireworm Pheletes californicus at Al- 
hambra, Calif., are reported by Roy E. Campbell. Results of these ex- 
periments indicate "that larvae can readily exist on very small amounts 
of food for long periods of time. It is also evident that the length of 
the larval stage of wireworms may either be lengthened or shortened de- 
pending on the amount of food consumed or available. * * * the majority 
of larvae which hatched in 19350 may complete their life cycle during the 
spring of 1932, providing, however, that they have favorable moisture, 
temperature, and food conditions. * * * larvae do not necessarily have 
to be of a certain size in order for pupation to occur; furthermore, the 
policy of attempting to determine the age of larvae according to their 
size appears questionable."
