abstract
An experiment was conducted at the Department of Entomology, College of Horticulture, Dr Yashwant Singh Parmar University of Horticulture and Forestry, Nauni, Solan, Himachal Pradesh during 2014-15. A life table for M. incognita was developed on tomato cultivar 'Solan Lalima' under laboratory conditions. The mortality rates were very high during egg and J2 stages prior to root penetration. The mortality of subsequent life stages was low and virtually constant. Egg laying started on 22 day and egg laying was completely stopped on the 32 day of the pivotal age. The gross reproductive rate and net reproductive rate of the nematode on tomato was 396.16 eggs/ female. The species had the approximate generation time of 26.36 days. The innate capacity for natural increase was 0.20. The values of true intrinsic rate found to be 0.217. The average time taken by the species to complete one generation was 25.08 days. Finite rate of natural increase and doubling time were 1.53, 3.91 days respectively.
