Role of Animals in Agriculture

Insect Benefits and Uses

• Insect light traps can be used to grow mudfish, catfish, or tilapia by attracting insects that serve as a food source for the fish.
• Insects are beneficial in genetic and biological studies due to their simple body structure, rapid growth, and ability to produce multiple generations in a short period.

Insect Contributions to Soil and Water

• Burrowing insects contribute to soil fertility by creating channels for air and water to reach plant roots, improving soil aeration and drainage.
• Some insects are used as indicators for contaminants in drinking water, benefiting the health and well-being of humans and animals.

Insect Impact on Economy and Food

• Honey bees and wasps benefit economic crops by pollinating them, increasing yields and crop quality.
• Insects can impact stored food products and commerce by damaging or consuming food, leading to economic losses.

Insect-related Products and Hazards

• Silkworms produce silk by secreting a single thread of silk filament from their salivary glands, which is then wound onto a reel to create raw silk.
• Bee and wasp stings can cause harm to humans, including anaphylaxis in some cases.
• Termites, book lice, and some beetles can cause harm by damaging or consuming books, wood, and other materials.

Insect Control and Future Learning

• Efforts in controlling insects are relatively small compared to the losses incurred due to their impact on food and commerce.
• Crop protectionists can benefit from learning about insects to develop effective strategies for managing insect-related damage and improving crop yields.
• The next lesson will explore the concept of integrated pest management and its applications in agriculture and forestry.
