Linking demography and consumption of Henosepilachna vigintioctopunctata (Coleoptera: Coccinellidae) fed on Solanum photeinocarpum (Solanales: Solanaceae): With a new method to project the uncertainty of population growth and consumption
Journal of Economic Entomology 111 (1), 1-9
Abstract: Because life tables are capable of providing the most comprehensive description on the survival, stage differentiation, and the reproduction of animal populations, they can be considered as the bases of population ecology and pest management. Researchers concerned with studies involving life tables inevitably face the problem of describing the variabilities that occur in the survival, stage differentiation, and fecundity data. Finding a means to include these variabilities in population projections concerning pest management may be problematic. Henosepilachna vigintioctopunctata (F.) (Coleoptera: Coccinellidae) is a pest of many plant species in Asia, including cultivated crops, ornamentals, and wild plants. The raw life history data (survival, stage differentiation, and fecundity) and consumption rate of both sexes of H. vigintioctopunctata reared on Solanum photeinocarpum Nakamura et Odashima (Solanales: Solanaceae) were collected in the laboratory and analyzed based on the age-stage, two-sex life table theory. The intrinsic rate of increase (r), finite rate of increase (lambda) , net reproductive rate (R₀), mean generation time (T), and net consumption rate (C₀) of H. vigintioctopunctata were 0.1312 d^-1, 1.1402 d^-1, 603.5 offspring, 48.8 d, and 77.8 cm², respectively. By using the bootstrap technique with 100,000 samples, we demonstrated that the life tables constructed based on the 2.5th and 97.5th percentiles of R₀ and λ can be used to describe the variabilities found in the survival and fecundity curves and to project the uncertainty of population growth.
