41 
of over 300 puparia of the fall generation during December and January 
indicate that approximately 93 percent of the larvae are viable and that 
over 55 percent have reversed their position in the puparia. 
A CRANE FLY (Tipulidae) ' 
California. A. E. Michelbacher (March 21): On the 28th of February serious 
injury to a grain planting by tipulid larvae was observed near Niles. The 
stand was destroyed over a rather extensive area. 
T03ACC0 THRIPS ( Frankliniella fusca Hinds) 
Florida. J. R. Watson (March 20): Moderately abundant on rye during the latter 
part of February and March. 
CORN 
CORN EAR WORM ( Heliothis ob sol eta Fab.) 
New Jersey. T. J. Headlee, R. C. Burdette, and B. F. triggers (March): Diggings 
made for pupae in southern New Jersey showed all of them to be killed by 
the cold weather. 
Florida. J. R. Watson (March 20): The corn ear worm is scarce. 
Missouri. L. Haseman (March 21): Recent diggings show that some pupae have 
survived the winter. 
Texas. F. L. Thomas (March 20): The first eggs were found by Dr. R. K. Fletcher 
in alfalfa in 3urleson County today. 
ALFALFA 
ALFALFA WEEVIL ( Hypera postica G-yll.) 
California. E. 0. Essig (March 22): Alfalfa weevils are moderately abundant 
throughout infested areas. 
A. E. Michelbacher (March 21): The alfalfa weevil situation is as follows: 
In the Tracy area the weevil can "be found in all fields. On March 20 the 
highest population was encountered at Vernalis. There an average of 1,198 
larvae were collected to the 100 sweeps. In the field examined some damage 
was noticeable, although not of a serious nature. In all other fields 
examined the average number of larvae taken per 100 sweeps ranged from 
2 to 200, in which fields no damage is apparent. In the Pleasanton district 
average larval counts of from 67 to 516 were taken on March 15. Up to 
that time no injury was apparent, and every indication was that the alfalfa 
for the most part would reach maturity before much injury occurred. It is 
the young vigorously growing fields in which the larval counts remain very 
low. In the country about Niles the highest larval counts have been taken. 
In one field an average count of 2,020 was taken to the 100 sweeps on March 
14, and in other fields on the same date average counts of as high as 575 
were taken. One field was swept today and an average count of 754 larvae 
was collected. The average taken from this field on the 14th was 552. In 
this district some injury is noticeable, but this is not true of all fields.
