“Golden rain” Tree Extracts Show Promise as Eco-Friendly Palm Horn Beetle Control
KUALA LUMPUR – Research has uncovered that extracts from the S. multijuga tree, commonly known as “golden rain,” possess both attractant and insecticidal properties against the damaging palm horn beetle, offering a perhaps cheaper, more efficient, and environmentally friendly choice to synthetic pesticides.
The findings, recently published by researchers, reveal that synthetic pheromones derived from the tree can lure beetles, while extracts from its leaves, stems, and bark demonstrate direct toxicity. This dual-action potential is meaningful for the palm oil industry, which faces substantial economic losses due to the palm horn beetle’s destructive feeding habits. The research team believes the active compounds,potentially including pyridine alkaloids found in synthetic insecticides,could revolutionize pest management strategies.
Laboratory tests indicated that leaves were most effective at killing larvae, while stems and bark proved lethal to both larvae and adult beetles. Adult beetle mortality rates ranged from 12.5% to 25%,and larval mortality ranged from 1.25% to 3.75%. While these percentages are relatively low, researchers confirm the presence of bioactive compounds within the plant.
The discovery opens avenues for developing lasting pest control methods, reducing reliance on synthetic chemicals and minimizing environmental impact. Further research will focus on isolating and synthesizing the specific compounds responsible for the observed effects,paving the way for large-scale application in palm oil plantations.
