Abstract
Chemical compositions of host plants of the genus Albizia Durazz., viz., Albizia amara (Roxb.) Boiv., A. falcataria (L.) Fosberg, A. lebbeck (L.) Benth. and A. procera (Roxb.) Benth. and on the growth and development of Spirama retorta Clerck was studied. The larvae of S. retorta, is a serious pest of forest nurseries and young plantations in central regions of India. It devours young leaves and growing shoots, resulted in retardation in growth or mortality of the plants especially young seedling in nursery stage. The larva moulted through 6 or 7 instars. The different host plants exhibited to influence significantly on the larval survival, mortality, larval period, size and weight of various life stages and fecundity during development. On the basis of quality and chemical composition of different grade of host leaves, Albizia lebbeck is proved to be the most preferred favoured host plant than the other three species for the survival of this insect pest.
