A figure of 70 to 80 percent is considered normal as a survival level- -above 80 is high, 

 and under 70 is below normal. Weather and farm practices may well determine the extent 

 of the corn borer problem this summer. 



Fungus gnats are numerous in some wheat fields , as well as in many buildings and homes . 

 These small, gnat-like flies (sometimes mistaken for the Hessian fly) develop in wet, de- 

 caying organic matter. They manage to crawl through window screens, becoming a nuisance 

 in homes. Inside the home, a 0.1-percent pyrethrin space spray applied from a pressurized 

 can will give quick knockdown and relief. 



Clover leaf weevil populations remained about the same as last week. From 2 to 4 per squan 

 foot were found in the central section of the state. All were less than half -grown and wen 

 difficult to find. 



Watch new seedlings of red clover and alfalfa for leaf damage. The presence of warm, rainy 

 weather is favorable for a fungus disease. Such a disease will reduce the number of 

 weevils. 



Potato leafhoppers are now present in alfalfa around the southern half of the state. They 

 are small, green, wedge-shaped insects that skid sideways when disturbed. They cause 

 yellowing on second and third cuttings of alfalfa. No control is recommended at this time. 



Clover mites are also becoming annoying in some homes. These mites are tiny, orange-to- 

 black moving specks about the size of a pinhead. They cover furniture, walls, curtains, 

 window sills, etc. as they attempt to find their way outdoors. They can be picked up with 

 a vacuum cleaner, or an 0.1-percent pyrethrin spray from a pressurized spray can will 

 give quick relief. Before fall, remove grass, clover, and weeds next to the foundation- - 

 leaving a strip of soil at least 18 inches wide. This bare soil serves as a barrier to the 

 mites. Replanting this strip with flowers, such as zinnia, marigold, chrysanthemum, or 

 salvia will prevent a clover -mite problem next year. 



Winged termites and ants are appearing and are causing concern to homeowners. If swarms of 

 flying termites appear, check for mud tubes on inside basement walls and on the outside of 

 foundations. Many termite -control problems are extremely complicated and require an ex- 

 perienced exterminator.
