them as did not die from parasites or other causes while in the 

 ground, later came out in the adult or moth stage. 



Why they did not reappear in great numbers as larvae is not 

 plain. From our experience with the outbreak, we consider it im- 

 possible that the parasites and predacious enemies are responsible 

 for the reduction of the species. As has already been indicated, the 

 moths which we reared from the larvae, that we fed to full size, were 

 unable to lay eggs, and we think it cjuite possible that this fact ac- 

 counts for the failure of the insect to reappear in noticeable num- 

 bers, but we feel sure that some individuals in the open field would 

 be able to reproduce and that a careful search would reveal a few 

 specimens at any time. It is entirely possible that the species mav 

 again become injurious, but it is not likely that in very many years 

 the same species will again be injurious in the same locality. This 

 insect is present throughout the state and has been present for many 

 years and the next time it becomes noticeably abundant it may be 

 in some remote spot.
