"A Limiting Factor in the Abundance of Certain Parasitic Fossorial 

 Hymenoptera," by Theodore H. Frison, Urbana, 111. (5 minutes). 



Certain fossorial Hymenoptera, important white grub parasites, are often common 

 in one vicinity and not in another. As the adults are succivorous, the absence of a 

 suitable nectarous food supply is one of the limiting factors in their numerical 

 abundance. It is suggested that the propagation of certain plants in suitable 

 situations on golf courses or other areas, may somewhat lessen the damage ^used 

 by white grubs.

The injury first reported as a disease, proves to be purely a mechanical (or physical)

 data on stages of kernel when injury can occur and notes on relation of insects 

 to nuts and to legumes, etc., which are its natural food and breeding hosts.
