It now appears that borer development is ahead of corn development and that sur- 

 vival of first -generation borers should be generally low. Weather could still 

 change this situation; the next 2 weeks will determine the outcome. The most ad- 

 vanced fields of corn in the problem area should still be watched another 2 to 5 

 weeks for evidence of borer feeding. 



Soybeans 



Seed corn maggots were observed damaging soybeans. The maggots eat the germinat- 

 ing seed, and skips appear in the row of emerging beans. It is too late to con- 

 trol the maggot when damage is observed. 



Bean leaf beetles were observed eating holes in the leaves of newly emerging soy- 

 beans. Damage was not severe. If control becomes necessary, apply carbaryl 

 (Sevin) or toxaphene. 



Forage Insects 



Alfalfa weevil damage is about over. Spraying the new growth of the second crop 

 may still be justified in occasional alfalfa fields south of a line from Paris to 

 Alton. 



Alfalfa weevils have been found for the first time in Warren, Henderson, Mercer, 

 Boone, McHenry, Lee, and Mason counties. 



Stored-Grain Insects 



Stored-grain insects are lying in wait for wheat harvest, which is just around the 

 corner in southern sections. To protect stored wheat from insect damage, follow 

 these steps : 



1. Sweep up and clean out all old grain, chaff, and other debris inside and around 

 the storage bin. 



2. Apply a water-base spray of 1.5-percent premium-grade malathion (mix 5 ounces 

 of 50- to 57-percent malathion emulsion concentrate per gallon of water) or 



a 2.5-percent methoxychlor water-base (mix 14 ounces of 25-percent methoxychlor- 

 emulsion concentrate per gallon of water) to the ceiling, walls, and floor. 



5. If the wheat is to be stored for 1 month or longer, treat it with a premium- 

 grade malathion dust (40 to 60 pounds of 1 -percent dust per 1,000 bushels) or 

 spray (1 pint of 50- to 57-percent emulsion concentrate in 5 to 5 gallons of 

 water) . The dust is best applied on the surface of the wheat in the combine 

 hopper; the spray, as the wheat is augered or elevated into the bin. 



4, Clean out the combine hopper and auger. Throw away any grain remaining in 

 the hopper and auger from last season to prevent an infestation of the new 

 grain. 



Homeowner Insect Problems 



Sod webworm moths are emerging from larvae that survived the winter. The rapid 

 pupation and moth emergence being observed may cause some lawns to be damaged, 

 although first-generation worms are seldom numerous enough in lawns to cause
