Toledo, Ohio, “is the preponderance of fields disked as the major treat— 
ment. Fields of standing stalks still comprise a large portion of the 
remaining unworked fields. Large quantities of debris have been left on 
the surface of the fields and in general plowing continues to be of 
poor quality. Weather conditions have been favorable to the borer and 
judging from examinations in various types of overwintering quarters 
the larvae are in gocd condition. There has been no advance in mortal-—- 
ity over the last pericd." 
Larval mortality of corn borer at Toledo.—-Morris Schlosberg re- 
ports that "A survey made toward the end of April revealed approxi- 
mately 5 per cent of the larvae to be dead in the stalks and debris of 
cornfields in the neighborhood of the Toledo, Ohio, Farm. The live 
larvae appeared heavy and in excellent condition. Low temperatures 
prevailed but ample moisture was present in the stalks." 
Trap lights capture numerous flea hoppers.- Some interesting 
records have been obtained by W. W. Stanley at Knoxville, Tenn. (reported 
by F. W. Poos, Rosslyn, Va.) in trap-light collecting of flea hoppers 
studied in relation to the alfalfa yellows. These records are summarized 
as follows:

Other Empoasca (new or species not 12 
recognized) 
All males collected prior to June 1 and after September 14 were ex- 
amined. These specimens showed a greater proportion of species other 
than fabae than was found during the period June 1 to September 14. Em— 
poasca fabae was most abundant at the light from June 10 to. July 1. It 
seems logical to conclude that this is true in the field also since the 
many field collections which have been examined (internal genitalia) 
bear this out. The proportion of sexes, however, is almost entirely re—- 
versed at the light trap, as compared with field collections. Of the 
total of 2,619 Empoasca examined from these trap-light collections, 
74 per cent were males, whereas our field collections usually consist 
of approximately 75 per cent females."
