SEED CORN MAG-GOT ( Hylemyja cilicrura Rond.) 
Maryland. C. E. Andrus (May Jl): Erora 16.5 to 60.0 percent of the seedlings 
in two ■g'-acre plots of beans planted on May U at Beltsville were des- 
troyed by an unusually concerted attack of seed corn maggots. Counts 
made on May 20, based on a total of 2',607 plants from small samples, 
showed an average of 32.5 percent destroyed in one plot and 38 percent 
in the other. The above percentages of„ damage represent only seedlings 
in which the primary leaves were' completely'" destroyed. A large propor- 
tion of the remaining plants showed various degrees of injury, as did 
also the seedlings that had not yet emerged above the soil on the date 
of observation. It is estimated that not less than JO percent of. the 
early seedlings in these two plots were infested in some degree. Seed 
planted 1 week later in the first plot produced seedlings only 10. 5 per- 
cent of which were seriously damaged by the maggot.- Of 869 seedlings 
counted, only 93 were completely decapitated. 
Virginia. H. G. Walker and L. D. Anderson (May 25): Rather abundant early 
in the spring but has done little damage in the Norfolk district. 
Kentucky. W. A, Price (May 2U): Seed corn maggots are causing much loss to 
early planted corn, cucumber, and melon seed. 
Missouri. L. Haseman (May 26): During the first half of May numerous com- 
plaints were received of scattered heavy infestation of garden peas, 
melons, cucumbers, beans, and' corn. 
Nebraska. M. H.'Swenk (May 2H): Numerous complaints of damage were received 
from southeastern Nebraska during the latter half of May. 
Kansas. H. R. Bryson (May 2H): Several reports of this insect have been re- 
ceived. _ It has been reported attacking planted corn, kafir,.. melons, 
and beans. Soil conditions during the early part of the month were not 
favorable : to the gemination of seed. 
Oklahoma. F. A. Eenton (May 2U): The seed corn maggot was reported injuring 
corn at Okmulgee and McAlester. 
Utah. G. E. Knowlton (May 17): Seed corn maggot flies are very abundant in 
northern Utah in nearly all localities^ 
Washington. W. W. Baker (May 25): Peas, at Auburn, King County, planted on 
cabbage and cauliflower ground about a v;eek after the first crops were 
plowed under, are so severely damaged that the operators think they will 
have to replant in order to obtain a profitable stand. Estimate of 
damage by grower, 35 percent.
