Note générale : Special Edition

Résumé : #Scapanes australis# is a major insect pest of coconut palms in Papua New Guinea. Field observations showed that on host plants like coconuts, male #Scapanes# always attracted females and other male members. Bucket traps were developed to lure #Scapanes# beetles using live males as attractant (bait). Live males feeding on sugarcane were placed singly in an inner bucket within a 10 litres bucket container with rectangular holes at the side for insect entry and soapy water inside for drowning the insects. #Scapanes# populations were continuously monitored by traps and results indicated a gradual decline in the #Scapanes# population over time. Traps were also placed in the field to see if losses to coconuts used by #Scapanes# can be reduced. Results indicated that the reduction in trap catches was not consistent. Further studies are required to study the physiological behavior of male #Scapanes# and to improve the technique of trapping of #Scapanes# with male member alone. The role of trapping #Scapanes# in pest management is discussed.
