INTRODUCTION
Bagworms (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
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 corbettipopulation
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
JUSTIFICATION
This study was done as there had been no study on
using pheromone trapping for
M. corbettiin Malaysia.
This study will provide control method of
M. corbettiwithout 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. corbettiin
population in plantation with pheromone trap and
plantation without pheromone trap
HYPOTHESIS.
H
o: There is no significance difference between the
M.
corbetti
population in plantation with pheromone
trap and plantation without pheromone trap.
H
o: 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.
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.
