APPENDIX IV 



Parasites 



The following list includes all of the Ggg, larval, and pupal parasites 

 which were reared from Malacosoma during this study. The collection 

 number, nearest landmark, and state are given for all but a few collec- 

 tions that were made by other people or at other times; the complete 

 collection data can be obtained from Appendix I. 



We wish to thank the following individuals to whom we are most 

 grateful for the identification of the listed parasites : Dr. B. D. Burks of 

 the United States Department of Agriculture, United States National 

 Museum, who identified all of the Chalcidoidea except the Scelionidae 

 which were identified by Dr. Paul Marsh of the same organization; 

 Dr. Henry K. Townes, American Entomological Institute, Ann Arbor, 

 Michigan, who identified the ichneumonids ; Dr. C. F. W. Muesebeck, 

 U.S. National Mvxseum, who identified the braconids (except the 

 Rogas which it has not been possible to have identified as to species at 

 the present time) ; and Dr. H. J. Reinhard, Texas A. and M, University, 

 who identified the tachinids (with the exception that F. W. Stehr is 

 responsible for the specific identifications of the genus Lespesia using 

 Beneway's 1963 revision). Without their prompt cooperation this list 

 of parasites could not have been included in this publication. All of 

 the specimens are in the University of Minnesota Insect Collection 

 except for a few which were retained by the persons who made the 

 identifications. 



Egg Parasites 



As oudined in Appendix I, one or more egg masses were collected 

 for each collection at each locality whenever possible. The number of 

 egg masses per collection varied from zero to as high as 23, and is given 

 in Appendix I. These egg masses were held in 8-dram vials plugged 

 with cotton so any emerging parasites would be trapped for later ex- 

 amination. Nearly all egg masses wei'e collected after the larvae had 

 hatched, so any egg parasites which emerged before larval hatching 

 (such as Trichogramma) were missed. One or more egg masses were 

 found for 346 out of a total of 466 collections, but egg parasites were
