Summary: | Malaysia has the most developed oil palm industry in the world and this affects the overall agriculture
development of the country. The oil palm tree in Malaysia is Elaeis guineensis (African oil palm) and
the main pollinating agent is Elaeidobius kamerunicus (oil palm weevil). This study was conducted in
Bangka Semong oil palm plantation, Kota Samarahan, Sarawak to verify the occurrence of E.
kamerunicus in response to the productivity of oil palm. The result from this study showed that there
is a low occurrence of male flower inflorescences that anthesis (<1%) from 660 oil palm trees
sampled. The occurrence of oil palm weevil is higher in block F compared to A (Mann-Whitney U
test). The numbers of fresh fruit bunches sampled were significant different comparing four different
blocks (one-way ANOVA). The numbers of weevil presence is positively correlated with the numbers
of spikelet based on Spearman Rank Correlation test. However, there are no linear relationships
between the presence of weevils and the number of fresh fruit bunches or the average diameter of fruit
bunches. The findings of this study could provide the useful information on the relationship between
the occurrence of oil palm weevil and productivity. In addition, this study can serve as reference for
future studies and knowledge on the biology of these insects which is vital for better management of
oil palm yields. |
