INTEGRATED MANAGEMENT OF COCKCHAFER BEETLES IN OIL PALM

1. How the problem is detected

1.1

This problem has been recently detected by routine inspection of Block 4 by assistant

manager, newly planted oil palm seedling. did not look good from far and the canopy

was not the normal healthy green colour.

1.2On closer examination. the leaves of the seedlings were eaten by some pests.

1.3No pest was seen at the time of inspection during day time. only the fresh damage of

small holes due to recent feeding and some fresh tiny faeces were seen.

1.4Checking was carried out at 9 pm the same night using torch light after the Asst. Mgr

reported the incidence to the manager. They came to the Block 4 planting and found

many small brown colour beetles feeding on the leaves. Some beetles were collected

for sending to the agronomist for identification

2. Identify the problem giving the brief description of the problem, scientific name,

classification , biology , etc.

2.1

NAMA BIASA (BAHASA MALAYSIA) Kumbang Kaboi Hitam

NAMA BIASA (BAHASA INGGERIS) Black Cockchafers Beetle

NAMA SAINTIFIK Apogonia spp.

ORDER Coleoptera

FAMILI Scarabaeidae

2.2 FEATURES

Also attacking other plants such as sapodilla, rambutan, coffee and palm oil

Kaboi black beetle attack at night in large numbers and can cause serious damage, especially fora small tree

Active at night and hide during the day under a layer of dry leaves or in the soil at the base Poko

attacked

The entire body has a small hole spots

2.3 BIOLOGY

Only adults are attacking the leaves. Egg and larval stages not found in the leaves

EGGS: An-one in the land larvae: In the land and feed on organic material for 67-77 days

ADULT: Can live up to 4 months in the laboratory

3. Describe the damage symptoms, assess the severity and in your opinion the economic

significance.

Damage the buds and young leaves from the outside to the inside, including the veins

Black beetles can be found on the surface of young leaves Damage caused by species

Kaboi greatest when compared with other Kaboi

3.3 Legume cover crops are also damaged by these cockchafer beetles. Many weeds are

alternatives host plants with similar damage symptoms, irregular small holes on leaves.

3.3 In high population , very severe defoliation occurred after new seedlings were planted in

the field.

4. What are the control methods used (including a brief description how these carried

out taking into consideration the environmental and safety requirements) in line with

IPM

5. GIVE AN ESTIMATION OF COST BENEFIT RELATIONSHIP

5.1Crop loss =27% of FFB/ha

assuming 1styear FFB yield = 14 ton/ha and

oil extraction ratio (OER) = 15%

27% of 14 Ton/ha = 3.78 ton

3.78 ton FFB = 0.567 ton oil

5.2Crop loss/ha at different CPO price

CPO price RM/ton X Crop loss Crop Loss in RM/ha

3000 0.567 1701.00

2000 0.567 1134.00

1500 0.567 850.50

1000 0.567 567.00

5.3Spraying cypermethrin 0.05% to control cockchafer beetles

Cypermethrin 5% product = RM25 / liter

Spraying 1styear palms require 200 ml/palm insecticide solution

1 ha has 145 palms and requires 145 x 200 ml = 29000 ml (29 litres)

0.05 % = 100 ml of 5 % product in 10 litres water, or 290ml in 29 litersolution

290 ml = RM 25 x 290/1000 = RM 7.25

Water transport and tractor running = Rm 1.00 / ha

labour cost = RM40/name

One worker can spray 2 ha per day, cost of spraying = RM 20 / ha

Total cost/ha/round = cemical + labour + water / tractor running = RM7.25 +

20 + 1 = 28.256 round of soraying to completely control the outbreak, total cost = RM28.25

x 6 = RM 169.25

5.4Benefit = Crop Loss (prevented)cost of control

At current CPO prices of RM 1500/ ton, benefit = RM 850.50RM 169.25 = RM

681.25

By effectively controlling cockchafer beetles, a benefit of RM 681.25 per ha was

obtained.
