Entomology Course

Lesson 1 • Insect Diversity and Classification

Introduces the taxonomic hierarchy and the 30+ orders of class Insecta. Students gain a framework for identifying and grouping insects systematically.

Lesson 2 • History and Scope of Entomology

Traces entomology from ancient observation to modern applied science. Establishes why insects matter across agriculture, medicine, ecology, and industry.

Lesson 3 • Ecological Roles of Insects

Examines insects as pollinators, decomposers, predators, prey, and pests. Connects insect function to ecosystem services and economic impact.

Lesson 1 • Endocrine System and Hormones

Explains juvenile hormone, ecdysone, and their roles in growth and metamorphosis. Hormonal pathways are targets for insect growth regulator pesticides.

Lesson 2 • Reproductive System and Physiology

Details male and female reproductive anatomy, fertilisation, and egg production. Reproductive physiology is essential for population modelling and rearing programmes.

Lesson 3 • Nervous System and Sensory Organs

Maps the insect nervous system from brain ganglia to peripheral receptors. Sensory biology explains host-finding, mating signals, and behavioural responses.

Lesson 4 • Digestive and Excretory Systems

Describes gut structure, digestion mechanics, and waste elimination via Malpighian tubules. Understanding digestion informs pesticide uptake and nutritional rearing.

Lesson 1 • Egg Biology and Hatching

Covers egg structure, chorion function, embryogenesis, and hatching triggers. Egg biology informs sampling methods and early-season pest forecasting.

Lesson 2 • Pupal Stage and Adult Emergence

Describes pupal types, histolysis, organogenesis, and eclosion. Pupal biology affects timing of adult emergence and trap design.

Lesson 3 • Types of Metamorphosis

Contrasts ametabolous, hemimetabolous, and holometabolous development with examples. Metamorphosis type determines management timing and monitoring strategies.

Lesson 4 • Larval and Nymphal Biology

Examines feeding behaviour, moulting, and instar progression in immature insects. Larval stages are often the most damaging and most targetable phase.

Lesson 1 • Killing, Relaxing, and Pinning Specimens

Details safe killing agents, relaxing chambers, and pinning standards for dry collections. Proper technique preserves diagnostic characters for long-term study.

Lesson 2 • Digital and Molecular Identification Tools

Introduces image-based AI identification apps, DNA barcoding, and online databases. Digital tools accelerate identification and support citizen science programmes.

Lesson 3 • Morphological Identification Keys

Trains systematic use of dichotomous and polytomous keys to family level. Key use is the core skill linking specimen to name in applied entomology.

Lesson 4 • Wet Preservation and Slide Mounting

Explains alcohol preservation for soft-bodied insects and microscope slide preparation. These methods are essential for small insects and larval identification.

Lesson 1 • Mating Systems and Reproductive Strategies

Analyses courtship rituals, mate choice, and competition strategies across orders. Mating behaviour knowledge supports sterile insect technique and population suppression.

Lesson 2 • Foraging and Feeding Behaviour

Examines host selection, optimal foraging theory, and feeding specialisation. Foraging behaviour drives crop damage patterns and informs trap placement.

Lesson 3 • Chemical Communication and Pheromones

Covers semiochemical classes, pheromone biosynthesis, and signal reception. Pheromone knowledge enables mating disruption and monitoring trap design.

Lesson 4 • Dispersal, Migration, and Habitat Use

Describes flight behaviour, long-distance migration, and habitat selection cues. Dispersal patterns determine pest spread rates and biocontrol agent establishment.

Lesson 1 • IPM Programme Design and Evaluation

Guides students through building, implementing, and auditing a full IPM plan. Programme evaluation ensures continuous improvement and regulatory compliance.

Lesson 2 • Chemical Control and Pesticide Basics

Introduces pesticide classes, modes of action, and application principles within IPM. Chemical tools are used selectively to preserve natural enemies and resistance management.

Lesson 3 • Monitoring and Sampling Strategies

Covers sequential sampling, fixed-count plans, and remote sensing for pest detection. Reliable monitoring data are the foundation of every IPM decision.

Lesson 4 • Cultural and Physical Control Methods

Examines crop rotation, sanitation, row covers, and tillage as non-chemical tactics. Cultural controls reduce pest pressure before chemical intervention is needed.

Lesson 5 • Economic Thresholds and Pest Status

Defines economic injury level, action threshold, and pest categorisation. Threshold concepts prevent unnecessary treatments and guide cost-effective decisions.

Lesson 1 • Flies, Fleas, and Other Vectors

Covers biting flies, fleas, lice, and their roles in disease and myiasis. Diverse vector groups require tailored surveillance and control approaches.

Lesson 2 • Public Health Vector Control Programmes

Describes surveillance networks, insecticide resistance monitoring, and community engagement. Effective programmes integrate entomological data with public health infrastructure.

Lesson 3 • Vector Biology and Disease Transmission

Explains mechanical versus biological transmission and vector competence factors. Transmission biology determines which control points break the disease cycle.

Lesson 4 • Mosquito-Borne Diseases and Control

Covers mosquito biology, major mosquito-borne pathogens, and integrated vector management. Mosquitoes represent the highest-burden vector group globally.

Lesson 1 • Forensic Entomology Principles

Introduces succession ecology on remains, postmortem interval estimation, and courtroom evidence standards. Forensic entomology links insect biology to legal investigations.

Lesson 2 • Entomology in Environmental Assessment

Uses insect bioindicators to assess water quality, habitat health, and climate change impacts. Biomonitoring programmes rely on standardised insect sampling protocols.

Lesson 3 • Stored Product and Urban Pest Entomology

Covers grain beetles, moths, cockroaches, termites, and bed bugs in built environments. Urban and stored-product pests require specialised detection and treatment protocols.

Lesson 4 • Pollinator Conservation and Management

Examines managed honey bee colonies, native bee diversity, and pollinator habitat. Pollinator health directly affects crop yields and ecosystem function.
