CLOVER CULTURE. 



brief as follows : The adult insect hibernates and may be 

 found in sunny places in early soring, or, for that matter, at 

 any warm spell during the winter. It is about one-eighth oi 

 an inch long, and is shown in the figure at c much enlarged, 

 the line at the left being a little longer than the actual 

 length of the average specimens. It is broad in proportion 

 to length, and is marked with numerous dark blotches and 

 stripes. The adults pair during April and the females 

 deposit- eggs in the leaves of clover and probably also in

the petiole and perhaps also near the ground in the crown. 

 The first larvae appear during the month of May, though egg 

 deposition lasts for some time and larvae of this first brood 

 may be appearing for some weeks. Some of them mature, 

 producing the adults by early in July, and these deposit eggs 

 which produce a second brood of larvae, and it is possible that 

 the earliest maturing of these might produce a third brood, 

 but the bulk of the insects are doubtless included within 

 two broods. Remedial measures for this pest are not readily 

 applied and the only reccommendation that seems feasible at 

 present is to use the flat "hopper-dozer," or "Tar Pan," which 

 has been proven at the Iowa Experiment Station to be so effec- 

 tive in killing the leaf -hoppers in pastures and meadows. It 

 will also serve to diminish their numbers greatly to burn over 

 the old grass, along fences and other places where the insects 

 hibernate, during late fall or early spring. The "Tar Pan" 

 could be best used in summer, directly after the cutting of the 

 first crop of clover.
