[Establishment and analysis of laboratory population life table of Trichogramma dendrolimi developed on Antherea pernyi eggs].
The laboratory population life table of Trichogramma dendrolimi Matsumura developed on the eggs of Antherea pernyi was established by calculating the survival rate at immature stage and the adult reproduction. The survival rate of egg, larval and pupa was 1.00, 0.9186 and 0.8895, respectively, and the emergence rate of pupa was 0.8668. The total mortality rate at immature stage reached to 30%, which was a great difference from those developed on small host eggs. Each Trichogramma female could lay about 86 eggs on one Antherea pernyi egg. The index of Trichogramma population trend was 54.48. Analysis on the relationships among intrinsic rate of natural increase (rm), net production rate (R0) and index of population trend (I) showed that the R0 and I had the same biological meaning, and rm could be calculated with I value.
