For control, use a grade of malathion labeled for use on stored grains. If a dust 

 is used, apply 15 pounds of the 1.0-percent dust per 500 square feet of surface. If 

 a spray is used, mix 5 ounces of the malathion liquid concentrate in a gallon of water 

 and apply 1 gallon of this mixture per 500 square feet. In addition, spray the walls 

 and ceiling of the bin above the grain. A fumigant-type insecticide will kill the 

 meal moths both on and in the wheat, but a fumigant does not prevent reinfestation. 



HOMEOWNER INSECT PROBLEMS 



Here is some good advice, slightly adapted, from the Purdue University Insect Newsletter. 

 Large numbers of insects can be seen on warm evenings, swarming around lights. These 

 insects find their way into homes and buildings, making a general nuisance of them- 

 selves. Insecticides are of little help, since within a few minutes after applying a 

 quick-knockdown space spray, there are more insects back at the light. You can help 

 lessen the problem by the type of lighting you use. Avoid strong, direct, white 

 lighting. Indirect or more subdued lighting is preferable. Indoor lights that shine 

 directly out of an opening should also be avoided. Colored walls that do not reflect 

 light are preferable to glossy white. Where possible, use yellow bulbs. Also a 

 bright light set in a tree, on a pole, or corner of a building some distance from 

 doors and windows will attract most of the insects and help lessen the number that 

 enter the building. 



Leafhoppers attracted to lights have been particularly annoying recently. These are 

 wedge-shaped green insects found by the hundreds at lights. 



Second-generation sod webworm moths have been emerging and laying eggs in lawns. This 

 egg-laying will continue for several more weeks. Apply ample fertilizer and water to 

 the lawn to help lessen the possibility of serious damage by these insects. Once 

 started, this program must be continued to avoid serious damage. If needed, an 

 application of carbaryl (Sevin) or diazinon as a spray or granules will effectively 

 control the worms for a week or two. A good time to apply the treatment is about two 

 weeks after a heavy moth flight. An additional treatment may be needed if egg-laying 

 continues heavy into late August. 



Millipedes are moving into homes from shrubbery beds, lawns, storm sewers, and nearby 

 wasteland with a heavy trash cover. These migrations are somewhat earlier than normal 

 (August and September) this year. It is usually the cool weather that causes them to 

 seek shelter in homes. These brown or gray, hard-shelled, slow-moving, wormlike animals 

 have two legs per body segment. They are sometimes called "thousand- leggers," and will 

 curl up in a tight coil when disturbed. Although harmless, they make a general nuisance 

 of themselves in the home, clustering in basements and garages. 



In cases of heavy- migrations, spray lawns and shrubbery beds with carbaryl (Sevin), 

 diazinon, or trichlorfon (Dylox) . This provides a barrier zone in which the millipedes 

 are killed, and prevents them from gaining access to the house. If migrations persist, 

 repeat the treatment in a week or two. For minor problems, spray shrubbery beds and 

 a 3- to 4-foot wide area around the foundation of the house for control. The general 

 lawn treatment will also control sod webworms and leafhoppers , but it is ineffective 

 against grubs.

LEAF BLIGHTS THREATEN CORN CROP 



Three corn leaf blights --northern, southern, and yellow leaf blight- -now threaten the 

 Illinois corn crop. All three blights are caused by fungi that infect the leaves when
