fields. These insects will mature within the next two weeks, and damage will cease. 

 Ordinarily, the plants recuperate reasonably well frcm this damage. Wireworms are 

 also being reported. They attack seeds and later drill holes into the base of 

 plants, killing them. 



Little can be done to control these insects now. Soil treatments with 

 aldrin or heptachlor prior to or at planting provide protection. 



Wind damage : Severe winds have whipped and frayed corn plants. Sand or 

 fine dirt has blasted the leaves until they are white, and tap roots have been 

 broken, allowing the plant to tip over. With moisture the plants will recuperate. 

 Insects are not involved. 



Hessian fly ; A spring generation has developed from flies that wintered 

 in early-planted wheat. This spring infestation is reported to be severe in seme 

 areas . 



Face flies : This new fly that clusters about the eyes and nostrils of 

 cattle is becoming more numerous and apparently will be quite noticeable by early 

 to mid-July. At present the only recommended control is to apply repellents and 

 pyrethrins to the head of the animal as sprays or specially prepared smears. 



Bean leaf beetle : Green, red o.r yellow beetles with black spots on their 

 backs are feeding on beans. The leaves of plants appear to have been peppered with 

 a shotgun. In cases of damage to the point of plant kill, apply l/h pound of 

 dieldrin, 1 1/2 pounds of toxaphene or 1 1/2 pounds of DDT per acre. 



Caution : Before applying insecticides, read labels carefully and follow 

 all precautions. This not only will insure personal safety, but will also eliminate 

 insecticide residue hazards. 



NOT FOR PUBLICATION — Special note to farm advisers and assistant farm 

 advisers: k-E members will soon begin making their summer project plans. Members 

 enrolled in the entomology project can obtain a free packet of 50 insect pins by 

 writing to Stevenson Moore, 280 Natural Resources Building, Urbana, Illinois. Be 

 .sure to obtain a supply of the new k-E Entomology Record Book (BP-23)> which also 

 contains cut-out labels for collections. In addition, insect -mounting boxes can be 

 purchased by members. Refer to the recent mimeograph on this subject for address 

 and price. 



This weekly report was prepared by H. B. Petty, Illinois Agricultural Ex-

 Agricultural Service, Plant Pest Control Branch, from information gathered by ento- 

 mologists and cooperators who send in weekly reports from their own localities.
