Life tables and the intrinsic rate of increase of Earias vittella (Lepidoptera: Noctuidae) reared on different hosts
International Journal of Tropical Insect Science 25 (2), 73-79
Abstract: Life table studies of Earias vittella (Fabricius) on different hosts in the Insect Biotech Laboratory, Department of Entomology, Dr PDKV Akola, revealed that survival (lx) of immature stages of E. vittella on different hosts was 0.65 on okra, 0.56 on cotton, 0.54 on semi-synthetic diet and 0.51 on mesta. The net reproductive rate (Ro), at the end of each generation, of E. vittella was 81.91 on okra, 56.70 on cotton, 53.02 on semi-synthetic diet and 36.63 on mesta (Hibiscus cannabinus L.). The net reproductive rate (Ro) followed the same order as the survival rate (lx) on the different hosts. The innate capacity for increase in numbers (rm) ranged between 0.0888 and 0.1334 females/female/day. In descending order, the rm values on different hosts were okra (0.1334), cotton (0.1111), semi-synthetic diet (0.1029) and mesta (0.0888).

L'étude de la table de vie de E. vittella (Fabricius) élevé sur différentes plantes hôtes et sur milieu artificiel au laboratoire de Biotechnologie des insectes, du département d'entomologie (Dr PDKV Akola), a révélé que le taux de survie (lx) des stades immatures d' E. vittella sur les différents substrats est de 0,65 sur gombo, 0,56 sur coton, 054 sur milieu artificiel et 0,51 sur mesta (Hibiscus cannabinus L.). Le taux net de reproduction (Ro) d´E vittella par génération est de 81,91 sur gombo, 56,70 sur coton, 53,02 sur milieu artificiel et de 36,63 sur mesta. On observe une évolution comparable du taux net de reproduction (Ro) et du taux de survie sur les différents substrats. La capacité innée d'accroissement (rm) est comprise entre 0,0888 et 0,1334 femelles/femelle/jour. Les valeurs du rm sont par ordre décroissant 0,1334 (gombo), 0,1111 (coton), 0,1029 (milieu semi synthétique) et 0,0888 (mesta).
