SMALL GRAINS 



Cereal leaf beetles are present in isolated areas of Illinois. The Illinois and U.S. 

 Departments of Agriculture are cooperating in a suppression program. Malathion will 

 be applied at 3 ounces per acre. It is an insecticide commonly used by homeowners on 

 flowers, shrubs, and vegetables, and is no more toxic than aspirin if ingested. How- 

 ever, this insecticide is extremely toxic to the beetle--also to mosquitoes and flies. 

 Unfortunately, it is toxic to honey bees, too. Beekeepers have been warned by the State 

 Apiary Inspector to cover hives or move them from areas to be sprayed. Spraying will 

 begin on May 4 . 



Armyworm moth flight is increasing. Watch lodged spots in grain fields; also, grass 

 fields with luxuriant growth. Moths concentrate their egg-laying in these spots, and 

 the worms will appear there first. Worms should be noticeable in extreme southern 

 Illinois within 2 to 5 weeks; in south-central and central Illinois, within 3 to 5 week: 



Applications of 1 to 1-1/4 pounds of malathion, 1 pound of trichlorfon (Dylox) , 1-1/2 

 pounds of carbaryl (Sevin) , or toxaphene will control armyworms. Do not apply carbaryl 

 to small grains after the boot stage. Do not feed forage or straw treated with toxapher 

 or trichlorfon to dairy cattle, livestock being fattened for slaughter, or poultry. 

 There is no waiting period between the application of toxaphene and grain harvest; a 

 week is required when applying malathion, 21 days for trichlorfon. 



HOMEOWNER 



The seventeen-year locust or periodical cicada, Brood 



X, was a problem in 1953. This brood, the largest 



one in the eastern United States , is due to appear 



by May 20 in southern Illinois, and by about June 10 



in the northern 



part of the 



state. Emergence 



will reach a peak 



a few weeks 



later. 



In 1953, these 

 periodical cica- 

 das, were pre- 

 sent in swarms 

 in Vermilion, 

 Edgar, Clark, 

 Crawford , Law- 

 rence, Wabash, Ed- 

 wards , White , 

 Williamson, Ran- 

 dolph, Morgan, Knox, and Lee counties. They were 

 present from a few specimens to swarms in other 

 counties , as indicated on the map . 



Infestation during 1970 may well follow the 1953 

 pattern. We are anxious to update our records on 



distribution of this brood of cicadas in Illinois, in order to make more-accurate pre- 

 dictions for 1987. Please send us specimens of cicadas that you encounter, noting the 

 date and location (nearest town) . Please mail such specimens to Dr. Lewis J. Stannard, 

 285 Natural Resources Building, Urbana, Illinois 61801.
