Entomopathogenic Virus (Bilogical Control Agent) of Setora nitens L.

ADVANTAGES:

  • Safe for humans and other non-target organisms.
  • Reduction of pesticide residues in food.
  • Preservation of other natural enemies.
  • Increased biodiversity in managed ecosystems.
  • Alternative to chemical insecticides.
  • Reduce the risks of pollution.
  • Limits the development of resistance in their host.

USE OF ENTHOMOPATHOGENIC AGENTS

S. nitens L. (Nettle Caterpillar)

  • Order: LepidopteraFamily: Limacodidae
  • Serious insect pest of oil palm (Frond damage of 90%; 30% crop loss)
  • Defoliators
  • 3 Species: Darna trima, Setothosea assigna, S. nitens

DISADVANTAGES:

  • Narrow host range when targeting a variety of pests at one time.
  • Cost more if compared to chemicals pesticides.
  • Lack of knowledge on their existence by potential local farmers
  • Non-existence of regulation and registration guidelines
  • Do not give a lasting solution (a pest outbreak)
  • Variable efficacy.
  • Proper timing and application procedures.
  • Limited potential market due to treatment for specific pest only.

Conventional Method

(Chemical Control)

Aerial Spraying

Ground Spraying

Trunk Injection

CONCLUSION...

ISSUES & PROBLEMS

(Chemical Control)

ENTHOMOPATHOGENIC

  • The virus infecting S. nitens is very PROMISING as bioinsecticides
  • Infected caterpillars could be kept under Freezing Temperatures as a source (usage if needed)
  • The virus is SPHERICAL & ABSENT of envelope (observation under TEM)

Control velvet bean caterpillar in Brazil

Other POTENTIAL enthomopathogenic agents in M'sia

Baculovirus

  • Environment damage
  • Pollution
  • Toxicity to human & domestic animals
  • Development of Resistance & New pest
  • Damage to beneficial insects
  • Resistance phenomena

  • VIRUS
  • FUNGI
  • BACTERIA
  • NEMATODES

Control Rhinoceres Beetle in the Andaman Islands, India.
