The psocid Liposcelis bostrychophila is a worldwide stored product pest of various processed and unprocessed
dry foods in households, granaries and warehouses. Recently, post-harvest treatments are not recommended
owe to food safety awareness. Therefore, it is necessary to develop an alternative approach of chemical to manage
L. bostrychophila. However, knowledges of the life history and ecological adaptability of L. bostrychophila are
important for identifying the optimal timing to implement effective control measures. In this study, we investigated
the developmental and reproductive traits of L. bostrychophila at 9 constant temperatures from 15 to 35�C at 2.5�C
interval. The development period from egg to adult was decreased with the increasing of temperatures until 30�C,
then increased at 35�C. At 35�C, most of the laid eggs did not hatched. The lower developmental threshold (T0)
and the thermal constant (K) estimated by using a linear model were 12.9�C and 346.2 degree-days, respectively.
The average life span of L. bostrychophila was ca. 138 days at 25�C and ca. 90 days at 30�C. The intrinsic rate of
natural increase (rm) was 0.077 at 25�C and 0.138 at 30�C. Our results would be useful for assessing the overall
effects of temperature on L. bostrychophila and the temperature effects should take into consideration when use the
management program of this pest species.
