Red Palm Weevil (RPW), Rhynchophorus ferrugineus, is a serious pest of palms throughout South and Southeast Asia which
are the native habitat of this pest. The aim of this study was to assess survival and fertility characteristics of the
Red Palm Weevil (RPW), R. ferrugineus in the laboratory. Life tables and population parameters of the RPW were
constructed on sugarcane slices as a course food for RPW under laboratory conditions. The results showed that the
highest mortality occurred in 12thinstar. The life table analysis showed that the population density of RPW
decreased gradually. The survival ratio of male to female was 0.396:0.604. The females lived for a maximum
of 196 days. The highest number of eggs produced per female per day was 5. The intrinsic rate of increase (rm)
in egg production per female per day was 0.17 and the daily finite of increase (?) was 1.19 females per female per day,
with a mean generation time (T) of 25.15 days. The net reproductive rate (Ro) of the population was 70.18.
The population doubling time (DT) was 4.8 days.
