Green June beetles are large, clumsy "beetles that make a loud buzzing 

 sound when flying. Ordinarily no control measures are required, since their 

 feeding is not serious unless they concentrate on fruits, such as peaches. 



Face flies and stable flies were more numerous on cattle in northern 

 Illinois this week than they have been all summer. 



We have been asked to clarify our dairy cattle spray recommendation. 

 In I963 we found that 2$ Ciodrin in oil, applied four to five times a week, pro- 

 vided about 90 percent control of face flies and stable flies and 100 percent 

 control of horn flies on dairy cattle on pasture during the day. A spray of 1$ 

 Ciodrin and l/U$- DDVP provided 100 percent control of horn flies, but only 

 slightly over 50 percent control of face flies and stable flies when the cattle 

 were on pasture. For this reason we recommended that 2$ Ciodrin in oil, al- 

 though more costly than other sprays, would provide much better protection for 

 cattle during the pasture hours. 



Caution : Before applying insecticides, read the labels carefully and 

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

 eliminate insecticide residue hazards.
