Oil palm (Elaeis guineensis Jacq.) is one of the main plantation crops in Indonesia. The aroma of pollen and nectar from male oil palm flowers is attractive to pollinating insects. The lack of male flower availability in oil palm leads to a low population of E. kamerunicus due to habitat and food source limitations. The low population of pollinating insects results in sub-optimal oil palm produ…
Oil palm (Elaeis guineensis Jacq.) is one of the largest plantation commodities in Indonesia. Palm oil productivity depends on the amount of pollen from male flowers that falls onto female flowers. Oil palm pollination is carried out by natural pollinators such as Elaeidobius kamerunicus. The aroma of pollen and nectar from male oil palm flowers is favored by E. kamerunicus because it contains …
Visually identifying nettle caterpillars species is often difficult due to the similarity in shape between species. Therefore, the molecular identification approach using DNA barcoding methods, utilizing multigene mitochondrial markers such as COI, COII, and Cyt b, is expected to provide a more effective and scientific solution for specifically identifying pest species. The purpose of this stud…
Polyculture can increase land resource utilization and reduce the risk of crop failure in a single planting area.
