CHINCH BUG- ( Blissus leucopterus Say) 
Illinois. W. P. Flint (February 21): The chinch bug is present over all of 
the State with the exception of the extreme, northern and southern ends. 
Recent counts show a very low winter mortality, better than 90 per cent of 
the bugs being alive at this time. 
Iowa. C. J. Drake (February 17): The chinch bug is moderately abundant. It will 
probably do some damage --spot ted — in 10 to 15 counties, in small areas. 
H. E. Jaques (February 21): Chinch bugs are apparently showing up in con- 
siderable abundance. During a warm' spell just preceding our last freeze they 
were crawling about in last summer's heavily infested area in the southern 
part of Henry County in large numbers. 
Missouri. L. Kaseman (February 22): Two cold spells coming with sudden temperature 
drops and the more or less continuous wet weather are not favorable for the 
chinch, bug* ... 
Kansas. H, H. Bryson (February 23): More chinch bugs went into hibernation at 
Manhattan during the fall of 1932 than was the case the preceding year. Counts 
made to determine the number of bugs hibernating in the vicinity of Manhattan 
showed an average of 40 bugs to the bunch of native prairie grass, with a 
mortality of 5 per cent. The dryness of the winter in the State has been 
conducive thus for to the successful overwintering of the bugs. 
Oklahoma. C. F. Stiles (March l): Chinch bugs were quite numerous in bunch grass 
along the roadside in Pawnee County before the last cold snap, but I have not 
had time to make a survey since that time. 
WHEAT JOINT WOKM ( Harmolita tritici Fitch) 
Oregon. Monthly letter of the Bureau of Entomology, No. 224 (December 1932): 
T. R. Chamberlin, November, Forest Grove, Oreg. , made an examination of the 
fall collection of wheat stubble from the sample farm in the Molalla district 
and found Harmolita tritici present in 28.2 per cent of the straws. The 
following parasites were also present, in the percentage indicated; Ditropinotus 
aureoviridis Cwf d. , 20.3 per cent; Eurytoma parva (Girault) Phillips, 48.2 perce- 
Eupelmus allynii (French) and Eupelminus saltator Lind. , 1.8 per cent; 
Calosota metallica Gah.. C.5 per cent; undetermined parasites, 1 per cent; 
total parasitization, 71.8 per cent. *** examinations showed that 78 other 
Eurytoma had been destroyed by secondaries as follows: Ditropinotus, 56; 
E. allynii and E. saltator , 15; Calosota, 4; undetermined parasites, 3. The 
original parasitization of Eurytoma in the cells as counted in the fall was 
thus 52.9 per cent. It was also found that 118 other Harmolita had been 
destroyed by Eurytoma larvae which 'had entered more than one cell. The number 
of Harmolita originally present was, therefore, greater by 118 than was 
indicated by the fall count and the total destruction of Harmolita by Eurytoma 
was 56.1 per cent and by all parasites was 73.1 per cent. *** Comparing the 
parasitization in the fall collection from the sample field in 1932 with that 
in the corresponding collection in 1931, the total destruction of Harmolita 
by E. parva has increased from 45.2 to 56.1 per cent. *** By the middle of the 
month most of the H. tritic i were still pupae, whereas in 1931 practically all 
had pupated by the first of the month."
