of cotton controls the beetles for 1 

 year. 



Certain chemical insecticides have 

 been used in the past to control white- 

 fringed beetles on cropland. However, 

 many States have adopted or are con- 

 sidering restrictive legislation affecting 

 the use of these insecticides. For cur- 

 rent information about insecticides 

 approved for control of white-fringed 

 beetles in your State, consult your 

 local agricultural agent or State agri- 

 cultural experiment station. 



Nonagricuitural Land 



Federal or State quarantine pro- 

 grams may require you to control 

 white-fringed beetles on nonagricuitural 

 land. These include fields not used for 

 growing crops or grazing, for nurs- 

 eries, storage areas, railroad yards, 

 sidings, and roadways. Treatments are 

 applied under the supervision of Fed- 

 eral and State plant protection workers. 

 Consult them for additional informa- 

 tion about insecticides currently ap- 

 proved for these treatments, proper 

 rates of application, and other details. 



Quarantines 



To prevent the spread of white- 

 fringed beetles, Federal and State 

 quarantines have been estab- 

 lished. These quarantines are de- 

 signed to control the movement 

 of articles that could carry the 

 pests. 



In quarantined areas, plants 

 with roots attached, certain crops, 

 equipment, soil, forest products, 

 and other articles must be certi- 

 fied by a plant protection in- 

 spector before they can be 

 shipped to uninfested areas. To 

 be eligible for certification, the 

 articles must be treated or found 

 to be free of white-fringed beetles. 



For further information about 

 State and Federal quarantine 

 regulations contact your State de- 

 partment of agriculture, county 

 agricultural agent, or a plant pro- 

 tection office of the U.S. Depart- 

 ment of Agriculture. 



FINDING AND 



REPORTING 

 INFESTATIONS 



You can help prevent the spread of 

 white-fringed beetles by finding and 

 reporting infestations. 



Finding Larvae 



• Look around roots, particularly 

 if plants are wilting or dying. 



• Look for wilting, reddening, and 

 yellowing of young plants in fields, 

 vegetable gardens, and flower beds. 

 Examine the soil where there are skips 

 in rows of plants. 



• Dig up abnormal plants and look 



for larvae in the soil and on the roots. 

 Examine several plants that are wilting 

 or yellowing. 



Finding Adult Beetles 



• Look for sawtooth cuts on outer 

 edges of leaves; adults do not eat holes 

 in the leaves. (See photo, p. 2.) 



• Look for damage on leaves of 

 crops such as soybeans, velvetbeans, 

 peanuts, cotton, and clover. 



• Look for adults on broadleaf 

 weeds in fields, terraces, turnrows, and 

 fence lines. If weeds and small grains 

 are growing in the same field, beetles 

 will feed on the weeds.
