BIBLIOGRAPHY OF TERMITES I955-60: SUBJECTS — SNYDER 



Karlson, P., and Butenhand, A., 1959, pp. 

 49-51. (Ectohormones of termites pro- 

 duced by reproductives influence colony 

 members, refers to Grassi and Sandias, 

 Grasse, et al., Light and Luschner.) 



Luscher, M., 1958b, pp. 144-150. (Effect of 

 corpora allata on the origin of substitute 

 reproductives.) 

 i960, pp. 549-563. (Europe, Kalotermes 

 flavicollis, caste determination is con- 

 trolled by hormones, after each pseudoer- 

 gate molt corpora allata secrete juvenile 

 hormone bringing individual into reac- 

 tive state of competence for differentia- 

 tion. The relative duration and intensity 



of secretion of the different endocrine 

 glands bring about differentiation.) 



Luscher, M., and Springhetti, A., i960, pp. 

 190-212. (Europe, Kalotermes flavicollis, 

 role of corpora allata, seems to produce 

 two different kinds of hormones, the 

 juvenile hormone probably increases the 

 competence for supplementary reproduc- 

 tive differentiation. The gonadotropic 

 hormone initiates presoldier differentia- 

 tion.)

 Congo, Macrotermitinae take soils from 

 depth, texture finer in mounds than in 

 adjacent soils; no difference for Ami- 

 termes mounds; mounds Cubitermes and 

 Nasutitermes have greater rate fine ele- 

 ments than surrounding soils which con- 

 tain important amount of iron oxide con- 

 cretions. Mounds Macrotermitinae poorer 

 in organic matter than adjacent land, 

 but contrary occurs in mounds Cubi- 

 termes, Nasutitermes, and Amitermes.)
