The most extensive program for biologicalĬontrol of the rhinoceros beetle was in Fiji where the pest was first found Movement on the ground of the adult beetle. ![]() Works is not certain, but it seems possible that it impedes the flight or Very intensive inspections of rotting logs ruled out the possibility that theĮffect was due to a greater number of beetles developing on the bare Cover works against the adult's searching for a feeding site since ![]() The trials confirmed that under heavy cover there was substantially Ground cover in young oil palm plantings may beĮither a natural cover, comprising self perpetuating species of grasses, fernsĪnd creepers, or a planted leguminous cover. Planters had for long held that a heavyĬover of ground vegetation was associated with reduced attack by the beetles,Īnd this agreed with observations in coconuts in the South Pacific (Owen The rotting away of logs or of destroying them completely at replanting. The rotting tissues of a former stand unusable by the beetle, of speeding up Wood (1969a) reported that a series ofĮxperiments was commenced in 1962 to investigate the possibility of rendering This procedure proved very expensive but not highly effective. Control was attempted by breaking up the breeding grounds and Insecticidal control is not very effective, andĬan lead de outbreaks of leaf-eating caterpillars. Organisms may enter the lesions, leading to long periods of distorted leaf Unopened leaves, or spears, so that newly emerging leaves are broken off, ![]() The beetles attack the heart of the palm, boring at the base of Larvae, which develop in rotting organic materials. Stand of oil palms, rubber or coconuts provide breeding grounds for the In replantings were especially at risk because the decaying logs of a former Southern Asia for many years and became a potentially devastating pest of This scarab was a major pest of coconuts throughout
