Greater Banded Hornet Overview

The Greater Banded Hornet (Vespa tropica) is a species of wasp found in various regions such as Southern Asia, New Guinea, and West Africa. They are known for inhabiting forests and nesting in tree hollows or subterranean cavities.

These hornets build their nests in a sealed environment, maintaining a stable temperature. As part of the genus Vespa, they are related to other well-known wasp species. Greater Banded Hornets play a crucial ecological role as predators of dragonflies and other insects.

Key Features of Greater Banded Hornet:

• Belongs to genus Vespa
• Inhabits Southern Asia, New Guinea, and West Africa
• Prefers forests, tree hollows, or subterranean cavities for nesting
• Maintains a stable temperature within the nest

Life Cycle and Behavior

Workers and Queens

• Workers and queens play distinct roles in greater banded hornet colonies
• Queens are responsible for laying eggs, while workers take care of the nest and forage for food

Nests and Colonies

Greater banded hornets create nests made of chewed wood fibers mixed with their saliva. These nests can be found in a variety of locations such as trees, shrubs, and even buildings.

• Nests house multiple generations of hornets
• Colonies consist of a single queen, many workers, and larvae

Preying on Honeybees

Greater banded hornets are predators of honeybees and may attack honeybee hives to obtain food.

• They are known to be aggressive towards honeybee colonies
• Hornets can cause significant damage to the honeybee population

In summary, the life cycle and behavior of the greater banded hornet involves a colony structure with a queen, workers, and larvae. They build nests from chewed wood fibers and saliva, and are known to prey aggressively on honeybees.

Greater Banded Hornet and Human Interactions

Stings and Health Hazards

• Stings: Greater Banded Hornet stings can be quite painful, given that they deliver venom through their stinger.
• Allergies: Some people may experience allergies or severe reactions to the venom, which can lead to hospitalization.

For example, the elderly are particularly vulnerable to stings and may suffer complications, such as difficulty breathing and a rapid drop in blood pressure, requiring immediate medical attention.

Impact on Gardens and Environment

• Nests: Greater Banded Hornets build nests that can disrupt human activity in gardens and surrounding areas, leading to potential encounters and stings.
• Garden plants: These hornets can sometimes be beneficial by preying on pest insects found in gardens, thereby helping to maintain a balanced ecosystem.

However, their efforts can inadvertently lead to the destruction of beneficial insects as well. In certain cases, such as their impact on Guam’s native ecosystems, the full consequences of their presence are yet to be determined¹.

Here is a comparison table highlighting the pros and cons of Greater Banded Hornets in gardens:

In conclusion, Greater Banded Hornets have notable interactions with humans, impacting both our health and gardens. Awareness of their stings, potential allergic reactions, and impact on the environment is essential to foster a harmonious coexistence.

Notable Species and Relatives

Asian Giant Hornet

The Asian Giant Hornet (Vespa mandarinia) is the largest hornet species in the world, with queens measuring up to 2 inches. They are known for their potent sting and aggressive behavior. Found in East Asia, these hornets are a significant threat to honeybees due to their predatory nature.

• Features:
  • Largest hornet species
  • Potent sting
  • Aggressive behavior

Japanese Giant Hornet

A subspecies of the Asian Giant Hornet, the Japanese Giant Hornet (Vespa mandarinia japonica) is native to Japan. They are similarly aggressive and a threat to honeybees. They can cause severe allergic reactions in humans when stung.

• Characteristics:
  • Subspecies of Asian Giant Hornet
  • Predatory nature
  • Severe stings

Oriental Hornet

The Oriental Hornet (Vespa orientalis) can be identified by its distinct yellow and brown coloration. Found in parts of Africa, Asia, and southern Europe, this species is less aggressive compared to the Asian Giant Hornet.

• Features:
  • Yellow and brown coloration
  • Less aggressive

European Hornet

The European Hornet (Vespa crabro) is native to Europe and Asia but has been introduced to North America. This species is more docile when compared to the Asian and Japanese Giant Hornets, but they can still deliver a painful sting.

• Characteristics:
  • Found in Europe, Asia, North America
  • More docile

Greater Banded Hornet Management and Control

Established Techniques

The control and management of Greater Banded Hornets involve a combination of methods to ensure the safety of humans and minimize damage to other pollinators like honey bees. Established techniques for controlling hornets include:

• Pesticides: Applying chemical treatments to the hornet nests to eliminate the colony.
• Physical removal: Engaging professional pest control companies to remove nests.

However, each approach has its pros and cons:

Traps

Hornet traps can be effective in capturing individual hornets or small groups. Some common types of hornet traps include:

• Bait traps: Using sweet substances to lure hornets into a trap where they cannot escape.
• Water traps: Filling a container with soapy water and a sweet bait to drown captured hornets.

Providing specific examples of each trap type:

• Bait trap example: Asian Giant Hornet lure trap
• Water trap example: Bucket trap with sugary bait

Reporting Sightings

Citizens play an important role in Greater Banded Hornet management. If you suspect a hornet sighting or nest, contact local pest control companies or wildlife authorities immediately.

For example, in the United States, the National Pesticide Information Center can provide guidance on who to contact in your region.
