INTRODUCTIONBagworms (Lepidoptera: Psychidae)

are leaf eating caterpillars, recognized by the distinctive bag which made from tough silk (Barlow, 1982).

In Malaysia, bagworms are common pest which infected orchard, landscape and ornamental tree (Ahmad and Ho, 1980).

Infestation of bagworms in oil palm plantation could inflict great loss in the production yield.

Common species of bagworms that can be found in oil palm plantation are Metisa plana, Pteroma pendula, and Mahasena corbetti.

Mahasena corbetti is a major pest in Eastern Sabah but not in peninsular Malaysia, (Wood & Nesbit, 1969).

Bagworms attack all stage of palms but bring more severe damage in mature palms as the dispersal is via overlapping of fronds (Basri, 2003).

The damage is caused by the young larvae that scrapes leaf epidermis and late larvae that creates hole on the leaves (Basri, 2003).

Even with moderate attack of 10-50% of leaf damage, it may cause severe loss about 43% production yield Basri, 2003).

There are many methods used to control Mahasena corbetti population in oil palm plantation.

Pheromone traps has not yet been used to control the bagworm population in Sabah oil palm plantation.

Live, virgin females hung within a sticky vane trap and placed in high concentration of bagworm populations in the field to attract male moths.

The sticky trap will serves to trap the males.

JUSTIFICATIONThis study was done as there had been no

study on using pheromone trapping for M. corbetti in Malaysia.

This study will provide control method of M. corbetti without using chemical insecticide. Thus, providing a sustainable agriculture practice for farmers.

This methods is an easier option for smallholders to adopt as trunk injection can only be use by trained personnels.

OBJECTIVES To evaluate the effectiveness of pheromone

trap as a control method for M. corbetti.

To compare the population of M. corbetti in population in plantation with pheromone trap and plantation without pheromone trap

HYPOTHESIS.Ho : There is no significance difference between

the M. corbetti population in plantation with

pheromone trap and plantation without pheromone trap.

Ho : There is a significance difference between the M.

corbetti population in plantation with pheromone

trap and plantation without pheromone trap.

LITERATURE REVIEW. The first study on potential of using pheromone trap

for monitoring and controlling Metisa plana in smallholder plantation with oil palm aged about 4 years. The study was done in Teluk Intan, Perak.

Receptive virgin female was used as pheromone source since no sex pheromone for Metisa plana had been developed thus far (Norman & Othman, 2006).

Norman and Othman had used 3 types of traps (Delta, Open-Delta, and Vane) to evaluate which traps will be effective to catch the male bagworms.

Vane traps appeared to be the most affective as the mean catches of moths per night in it was significantly greater than in other traps (Norman & Othman, 2006).

The rates of Metisa plana female bag which produced offspring in trap-treated plot were significantly lower than those in control plot (Norman & Othman, 2006).

Another study was done in the same district with different palms ages (16 years, 7 years and 6 years) in smallholder plantation to evaluate the efficiency of pheromone trapping as a control method.

The study was also done to determine suitable trapping height. There was no significant different in number of male moth captured between 2m pole and 4m pole (Norman et al., 2009).

According to the study, the number of live larvae and the percentage of bags with eggs in the trapping plots were always relatively lower (9.1–28.2%) compared to the control plots (28.6–48.6%) (Norman et al., 2009).

Trap design- Sticky vane trap are made from two

zink (overlapping both zink) plates (30 x 30cm).Receptive female will be placed on each plane of the trap. Polybutene glue sprayed evenly on each plane.

Trapping location- One trapping plot and one control

plot are put at the infested block.3 different location were chosen.

- Each location has different ages of oil palm (16, 7 and 6 years). Each block was named A, B and C.

- Each of plot consist of 6 x 18 palms.For each plots, ten traps were placed with distance of 18m each.

METHODOLOGY

Control plot- Similar in size with traps. Located approximately

100-200 meters away from the trapping plot.

Experiment procedures.- Sticky traps were hung on wooden poles 2m tall and

surrounded by palms of approximately 11m tall.- Randomized complete block design was used. Three

replicates for each trap height and five traps per replicate.

- Captures were recorded up to 14 days with the frequency of trapping every 2-3 months.

- The effects of mass trapping were determined. This was done by dissecting the female bags to determine the percentage of bags with eggs.

- The result above indicates mating and reproduction success, bagworm larval numbers and damage ranking of palms.
