During the last severe outbreak of larvae of Melohnlha, the 

 author observed that the greatest damage was done on those fields 

 which were under clover when the adults last appeared in large 

 numbers. This recurs once in every four years, and the maximum 

 amount of injury is noticed two years afterwards, when the larvae have 

 become mature. As the females prefer friable soil for oviposition, 

 the author suggests that in the year when the adults appear, or the 

 year previously, wide strips of oats and red clover should be sown 

 around forests. These should be separated from the remaining fields 

 by a trench 2 feet deep, with vertical walls. During the third summer, 

 these strips must be ploughed up and the larvae picked out of them. 

 In orchards, trap-plants may be used, such as strawberries, salad and 

 beet, the roots of all of which are very attractive to the larvae.
