Abstract
The life table of Lasioderma serricorne (F.), interspecific competition
between L. serricorne and Tribolium castaneum (Herbst), and Oryzaephilus
surinamensis (Linnaeus), and the influence of methoprene and pyriproxifen on the
biology of L. serricorne were investigated. Two strains of L. serricorne (USM and
Japan strains) were reared under optimum conditions of 30 ± 2°C, 70 ± 5% relative
humidity (r. h.), and 16-hour photoperiod. There was no significant difference (P
0.05) between the total development time for all immature stages, adult longevity,
and lifetime fecundity per female of the USM and the Japan strains. There were also
no significant differences (P < 0.05) between the two strains for population
parameters n, instantaneous rate of increase; net reproductive rate; and T, mean
generation time. L. serricorne was reared together in limited food source with T.
castaneum and O. surinamensis to study the effect of interspecific competition
between the three stored product beetles.
