(de Joannis, 1929)

Pteroma pendula is among most economically damaging pest of oil palm plantations in Malaysia and Indonesia, along with Metisa plana.[4][5][6] The caterpillars also feed on other trees and shrubs, including Acacia mangium, Delonix regia, Cassia fistula, and Callerya atropurpurea.[2][7] 31 different species have been identified as host plants for P. pendula.[8] Insecticides are the favoured method of controlling the moth in most commercial plantations.[8] Natural enemies such as predators, parasitoids, and fungi kill up to 4.85% of the population.[4][6][5]

Life cycle

edit

Survival rate of P. pendula eggs differs based on chosen host plant.[9] The species has six larval instars.[1][6] Pupae are typically found in middle and lower fronds, while caterpillars go higher in search fresh ones.[8] Dimorphism has been reported in the pupal and imago stages.[1][6] Males generally live longer than females.[9]

Damage symptoms

edit

P. pendula infestations can be detected by a number of symptoms. Holes in leaves and sometimes defoliation are some signs, and discolouration may also result.[1][7]
