dc.description.abstract | Investigations on biometricai analysis , biology, life tables and population dynamics of Achaea janata Linnaeus on different hosts viz., castor (Ricinus communis L.), ber (Ziziphus mauritiana L.), jojoba (Simmondisa chinesis L.) and pomegranate (Punica granatum L.) were carried out during the year 1988 and 1989 at Sardar Krushinagar. The biometricai analysis was carried out to test the aj)plicability of Dyar's law to the larvae of A. janata when reared on different hosts under laboratory condition. The measuranents of head capsule width of larvae fall into five well defined groups each indicating an instar, when larvae were reared on different hosts. The mean value of observed and calculated head capsules width and progression factor were close to each other which indicated that an increase in head width during successive Instar is in geometrical progression when larvae were reared on different hosts and it follows the Dyar’s law. The progression factors determined from the body length and width indicated the great deviation to provide any support for the theory suggested by Przibram’s and Megusar (1912). | en_US |
