Greenbrier (Smilax rotundifolia L.). 



No experiments were conducted on this species at the laboratory. 

 Observations in the field indicate that this species is seldom attacked. 



Sweetbrier (Rosa rubiglnosa L.). 



Mr. Schaffner found larvae in the first four stages feeding to a slight extent 

 on this foliage. 



No tray experiments were conducted. It is an unfavored plant. 



Butternut (Juglans cinerea L. ). 



Iu a single instance stripping of this species has been recorded. Mr. Proctor 

 observed this at North Andover, Mass. Other reports indicate very light 

 feeding. 



In trays at Melrose Highlands and Worcester males were reared from 100 

 second-stage larvae. The caterpillars fed very sparingly and grew slowly. This 

 is an unfavored food plant. 



Hardy Catalpa (Catalpa speciosa Warder). 



No observations were made on this species in the field. 



In the Melrose Highland laboratory the larvae started in the first stage all 

 died before molting. Each succeeding stage was tried, and a few lived long 

 enough to molt once before dying. No adults were obtained. A very unfavored 

 species. 



Red Cedar {Juniper us virginiana, L.). 



This tree is seldom eaten to any appreciable extent by gipsy-moth larvae, 

 and only in the worst infestations do they show the least feeding on the new 

 growth. It is a common occurrence at the end of the larval season to find 

 trees heavily infested, due to the larvae having sought shelter from the hot 

 July sun. 



Trays were started with this cedar at the Melrose Highlands laboratory, 

 using each succeeding stage of the larva? from the first to the fifth, inclusive. 

 No moths were produced as a result of feeding on this plant. 



Southern White Cedar (Chamwcyparis thyoides [L.] B.S.P.). 



Mr. Schaffner reports considerable feeding on these trees each year, and in 

 1913 it amounted to 75 per cent defoliation. 



Tray records indicate that it is an unfavored species, although one male moth 

 was obtained from 100 fourth-stage larvae. It is probable that solid stands of 

 this species will not be injured. 



Wintergreen (Ganlthcria procumhcns L.). 



Mr. Shinkwin notes feeding on the leaves of this plant by gipsy-moth larvae, 

 and in rare instances there was considerable eating of the fruit. 



No tray experiments have been carried on with Ibis species. It is unfavored 

 food. 



Choke Cherry (Padus nana (Du Roi) Roomer). 



This species is found as an undershrub in many wood lots. Very little let 'ding 

 has been noted by any of the observers, and that was done almosl wholly by the 

 first three stages, the small larvae making pinholes in the leaves.
