Abstract
A study on the implication of zero burning in the oil palm replanting program was carried
out in FELDA Plantations Sdn. Bhd., Lepar Utara Complex, Pahang. Damages caused by
rhinoceros beetles (RB) were assessed on different planting materials, palms of different
ages, palms planted on various land topographies (hillside, hilltop, roadside, border to
mature palm, swamp and valley) and various locations. Damages on oil palm trees in all
topographies were not significantly different (p>0.05). The 0 - 1 year tissue cultured
plants have higher damages caused by RB as compared to D x P (Dura x Pisifera).
A survey on the abundance of adult beetles was carried in a replanted oil palm in estates
of FELDA Lepar Utara 05, FELDA Lepar Utara 09, and FELDA Lepar Utara 14 of 0 - 3
years in approximately 120 hectares plot for 13 months using pheromone traps. High
numbers of adult rhinoceros beetles were caught in traps between 10th and 38th month
after felling (MAF) (EIL: 10 beetles/trap/week), and the beetle density started to decrease
39 MAF (below 10 beetles/trap/week). Rainfalls did not influence flying activities and
number of beetles caught (p>0.05) in the all traps locations. The abundance of Oryctes
rhinoceros in the decomposing trunk on different stages of beetle namely eggs, larvae,
prepupae, pupae and adult was carried out for 16 months period in approximately 40.00
hectares plot. Two types of breeding sites were selected, A: zero burning and B: partial
burning between 3 to 18 month after felling (MAF). Since 6th MAF, the populations of O.
rhinoceros were collected in trunk chipped however the highest population detected at
13th MAF and no bettle was detected at 3, 4 and 5th MAF of both sites. The third instar
larvae recorded as the dominant stage since the study was initiated except at 3, 4 and 5th
MAF. The difference practices through zero burning or partial burning of trunk chipped
did not influence (P>0.05) the abundance of all beetle stages except for first instar larvae
(p<0.05). Statistically, it was found that population of O. rhinoceross positively
significant due to the month after felling (ANOVA; F= 25.313: df= 6; p<0.05).
