abstract
An age specific, life and fertility tables of Lasioderma serricorne on different varieties of turmeric (Duggirala, Tekurpet, Mydukur local and Kasturi) were constructed and various life parameters were calculated at the dept. of Entomology, S.V. Agricultural college, Tirupati, at prevailing room temperature of 30 ± 2° C and 65 ± 5 % RH. Among turmeric varieties, the insect when reared on Tekurpet showed a high survival rate, life expectancy, net reproductive rate (51.37), fecundity (58), intrinsic rate of natural increase (0.0705), low mortality rate, mean generation time (56.06) and doubling time (9.84) and was ranked as susceptible variety. Similarly, the insect when reared on Kasturi showed low survival rate, life expectancy, net reproductive rate (21.67), fecundity (42.14), intrinsic rate of natural increase (0.0432) high mortality rate, mean generation time (71.08) and doubling time (16.12) and was ranked as tolerant variety.
