Red palm weevil (RPW), Rhynchophorus ferrugineus has been reported as a serious pest of coconut, sago and date in many parts the world.In Malaysia, RPW is lethal coconut Terengganu Sarawak.However, very limited information about reproductive performance available, specifically Malaysia.In present study, reared on (Metroxylon sagu) were studied using nine pairs virgin under laboratory conditions.The number eggs laid viability recorded daily until females could not produce eggs.The total 3081 average deposited by female was 342.3+0.97 (ranged from 270 to 396).The percentage hatchability 52.4% out 1614 hatched eggs, only 118 individuals (7.3%) survived late instar.However, no significant differences fecundity, larvae different observed.Females longevity found be strongly influenced laid; higher laid, shorter life span female.This study important understand biological aspects RPW, first step develop effective control strategy pest.
