InfoSAWIT, JAKARTA – The potential of the newly identified Elaidobius kamerunicus species to enhance palm oil productivity is promising. However, according to Marlon Sitanggang, Agronomy Division Head at PT Union Sampoerna Triputra Persada, the successful adoption of this new species requires a cautious and measured approach.
While the existing Elaidobius kamerunicus has significantly boosted palm oil productivity, it is not without its limitations. One key challenge is its dependence on environmental conditions. The beetle is highly sensitive to changes in temperature and humidity, factors that can impact its population and pollination activities. With the increasing unpredictability of climate change, this reliance poses a major sustainability risk for palm oil productivity.
Moreover, the current species is vulnerable to certain pests and diseases. Observations in the field have shown that natural predators like Cosmolestes bugs and spiders can reduce the beetle's pollination effectiveness. “Limited pollination efficiency is another issue, especially in large plantations where beetle populations may not be sufficient to meet pollination demands. Human activities, such as pesticide use, can further disrupt these populations,” Marlon told InfoSAWIT recently.
A lack of genetic diversity within Elaidobius kamerunicus populations is also a concern. If these beetles originate from a single source or have low genetic variation, they may struggle to adapt to environmental changes or new pathogen threats. Additionally, the pollination efficiency of Elaidobius kamerunicus may vary across different palm oil species. Some species may require supplementary or alternative pollinators to achieve optimal pollination levels.
Addressing these limitations through the development of new pollinator species or improved management practices could enhance the productivity and resilience of palm oil plantations. However, there is no guarantee that the new Elaidobius kamerunicus species will immediately boost productivity. Its success depends on thorough research and testing.
The new species must undergo extensive field trials across diverse climatic and soil conditions to ensure its ability to improve pollination efficiency and yields. Furthermore, the species must demonstrate adaptability to various environmental conditions distinct from its native habitat.
In this context, it is crucial to evaluate the pollination effectiveness of the new species compared to its predecessor. This can be measured by increases in fruit formation and fruit quality. Resistance to pests and diseases will also be a critical factor, as the new species must be more resilient to ensure stable and effective pollination.
The introduction of a new pollinator species holds significant promise for advancing palm oil sustainability, but careful assessment and strategic implementation are essential to realize its full potential. (T2)
