The oil palm weevil Temnoschoita quadripustulata Gyllenhall (Coleoptera: Curculionidae) is widely distributed in oil palm fields and plantations in Ghana. It is a key pest of nursery and young field palms less than 1 year old. Over the years, oil palm nursery operators and farmers have complained about attack of the pest on their young palms. This study on “The oil palm weevil T. quadripustulata: Damage and Control in young oil palms in Ghana” was carried out in response to oil palm farmers’ complaints in the Jukwa Area in the Central Region. The aim was to identify breeding sites of the pest, assess the damage on palms in farms, identify predisposing factors on infested farms and nurseries, and set up pesticide trial using Pyrethrum 5EC and Diazol 50EW at the laboratory to determine effectiveness of some insecticides for control of the pest. The results of survey showed clearly that most of the young palms killed on the farms were due to T. quadripustulata. Developmental stages of the weevil i.e. larvae, pupae and adults were found in almost all the fresh dead field palms examined, debris of decomposing oil palm logs and damaged palms. Most of the farms and nursery palms infested were poorly maintained. Pyrethrum 5EC was found to be slow-acting on T. quadripustulata and killed most of the insects only after 48 hours. The chemical however was able to immobilize most of the insects at all the concentrations till they died. Diazol 50EW showed 50% mortality within 24 hours and 100% in 80 hours.
