A CUCUMBER BEETLE ( Diabrotica tricincta Say) 
New Mexico R. Middlebrcok (July 13): Reports from the eastern half of the 
State indicate that these oeetles are doing much damage to cucumbers, 
cantaloupes and watermelons. 
MELONS 
MELON APHID ( Aphis gossypii Glov.) 
Indiana J. J. Davis (July 16): The melon aphid has been unusually abundant 
on cantaloupes in the southern part of Indiana. 
Iowa Fred D. Butcher (July 14): Aphids are very generally present on 
cucumbers, watermelons, and cantaloupes. Ladybugs and syrphids 
are fairly plentiful. 
California Roy E. Campbell (July 12): The melon aphid is appearing in various 
fields on single plants, but infestation is scattered and damage 
slight. 
ONIONS 
ONION MAGGOT ( Hvlemvia antiqua Meig.) 
Michigan W. L. Ward (June 6): The onion maggot is reported present at 
Falmouth. 
Oregon E. A. Hayes (June l): Large acreages of onions at Salem, are being 
damaged by 'this pest. 
wTREV/ORKS ( Agriotes mancus Say and Melanotus sp .) 
Indiana J. J, Davis (July 16): Wireworrs were reported destroying onions 
near Albion in the northeastern part of the State. Investigation 
July 2 revealed two species involved. One company reports losses 
amounting ^o from §15,000 tc $20,000. Wireworme of all ages were 
found. All of the ground, which is muck, is well drained, but much 
of it is new ground, and the wireworms were on the whole more des- 
tructive and numerous on the newer ground, as might be expected. 
It was interesting to note that where the seed row was rolled when 
seed was planted , the onions came up better and irade a much greater 
growth than elsewhere and as a result were least injured. The wire- 
worms appeared about the middle of June, at which time the plants in 
tne rows not rolled were much smaller and the small amount of injury 
to xhe plants was much more severe than on the larger plants in the 
rolled rews ; in fact the rolled rows were comparatively little 
damaged. From all data that could be gathered, comparatively little 
injury would have resulted, except possibly in the newest ground, had 
the seed rows all been rolled after planting.
