Entomology
Entomology is the branch of agricultural science that studies insects in relation to crops, stored products, ecosystems, and farm livelihoods. In agriculture, this includes both harmful insects that reduce yield and beneficial insects that support pollination and biological control.
Courses included in this section
This section currently includes course areas such as:
- Insect Morphology and Systematics
- Insect Ecology, IPM, Including Beneficial Insects
- Management of Beneficial Insects
Together, these courses help students move from insect identification to ecological understanding and then to practical pest-management decision making.
Why Entomology matters
Insects affect agriculture in many ways.
- Some damage leaves, stems, roots, grains, fruits, or storage produce.
- Some spread plant diseases.
- Some pollinate crops and improve yield.
- Some act as predators or parasitoids and help control pests naturally.
This means entomology is not only about killing insects. It is about understanding which insects matter, how they behave, what losses they cause, and how they should be managed intelligently.
Main learning themes
Students studying this section should expect to build understanding in:
- insect body structure and classification
- insect life cycles and behaviour
- ecological relationships between insects and crops
- pest status, economic threshold, and integrated pest management
- beneficial insects such as pollinators, predators, and parasitoids
- crop-specific and storage-pest management
How to study this section well
- Learn insects through symptom, insect, life stage, and management linkages.
- Do not separate morphology from field relevance; identification is useful because it supports the right management decision.
- Compare pests and beneficial insects side by side.
- Focus on IPM logic rather than pesticide names alone.
Who benefits most from this section
This subject area is especially useful for students interested in:
- crop protection
- pest scouting and field advisory work
- pesticide and biocontrol sectors
- integrated pest management
- higher studies in entomology or crop protection
Core takeaway
Entomology teaches students that insect management in agriculture is really about identification, ecology, threshold-based decision making, and balance between crop protection and beneficial insect conservation.
Frequently Asked Questions
What is entomology in agriculture?
Entomology in agriculture is the study of insects in relation to crops, stored produce, farm ecosystems, and livelihoods, including both harmful pests and beneficial insects.
Why is entomology important for BSc Agriculture students?
Entomology is important because insect pests can reduce yield and quality, spread plant diseases, and damage stored products, while beneficial insects support pollination and natural pest control.
What are beneficial insects in agriculture?
Beneficial insects are insects that help farming systems, mainly by pollinating crops or controlling pests as predators and parasitoids, so they are a key part of sustainable crop protection.
What is integrated pest management in simple words?
Integrated pest management, or IPM, is a decision-based approach that combines monitoring, insect biology, cultural methods, biological control, and need-based chemical use to manage pests safely and economically.
What is the difference between pest insects and beneficial insects?
Pest insects damage crops, stored produce, or farm resources, while beneficial insects support crop production directly or indirectly through pollination, predation, parasitism, or ecological balance.
Why is insect identification important in crop protection?
Correct identification is important because management depends on knowing which insect is present, which life stage is active, how it behaves, and whether it is harmful or beneficial.
