"The study and description of the physical form of insects."
Categorization of insects into groups based on their physical and biological characteristics.
Taxonomy: The science of classifying organisms to create a hierarchical system of groups based on their characteristics.
Morphology: The study of the physical form and structure of insects, including their external and internal structures.
Systematics: The study of the evolutionary relationships and diversification of insects based on their evolutionary history and relationships.
Phylogenetics: The study of the evolution and diversification of insects based on their genetic relationships.
Nomenclature: The naming of insects and their groups according to international rules and conventions.
Classification systems: The different systems that are used to classify insects, such as the Linnaean system and the cladistic system.
Species concepts: The different ways in which species are defined and classified based on their biological characteristics and evolutionary relationships.
Insect identification: The methods used to identify and classify insects based on their morphological, genetic, and ecological characteristics.
Insect diversity: The wide range of insect species and their ecological roles, including their interactions with other organisms and ecosystems.
Biological classification: The use of biological characteristics and relationships to categorize and classify insects into different groups and taxa.
Insect classification keys: The tools used to classify insects based on their morphological and biological characteristics.
Insect pests: The economic, ecological, and public health impacts of different insect pest species, and their management and control measures.
Insecticides: The different types of insecticides and their effectiveness in controlling different insect pests.
Insect biology: The basic biology and life cycles of insects, including their behavior, physiology, and development.
Insect ecology: The study of the interactions between insects and their environment, including their role in ecosystems and their impact on other organisms.
Morphological classification: This classification is based on the physical characteristics or morphology of insects such as their wings, antennae, body shape, and segmentation.
Biological classification: This classification is based on the biological characteristics of insects such as their behavior, life history, reproductive system, and physiological processes.
Phylogenetic classification: This classification is based on the evolutionary relationships among insects. It uses molecular data to construct a phylogenetic tree that shows the evolutionary history and relationships of various insect groups.
Taxonomic classification: This classification is based on the system of taxonomic nomenclature, which assigns a unique scientific name to each insect species based on its morphology and biological characteristics.
Ecological classification: This classification is based on the habitat and ecological niche of insects. It considers factors such as their feeding habits, interactions with other organisms, and environmental preferences.
Geographic classification: This classification is based on the geographic distribution of insects. It considers factors such as their range, migratory patterns, and adaptations to different environments.
Behavioral classification: This classification is based on the behavioral characteristics of insects such as their communication methods, social organization, predator-prey relationships, and reproductive behavior.
Genetic classification: This classification is based on the genetic makeup of insects. It uses molecular genetics techniques to examine the variation in genes and gene expression among different insect populations.
Paleontological classification: This classification is based on the fossil records of extinct insects. It provides information about the evolutionary history and relationships of various insect groups.
Applied classification: This classification is based on the practical applications of entomology in fields such as agriculture, medicine, and forensic science. It considers factors such as pest management strategies, insect-borne diseases, and the use of insects in forensic investigations.
"The terminology used to describe insects is similar to that used for other arthropods due to their shared evolutionary history."
"They have a body divided into three regions (called tagmata) (head, thorax, and abdomen), three pairs of legs, and mouthparts located outside of the head capsule."
"The non-insect hexapods, which include Protura, Diplura, and Collembola."
"Individuals can range from 0.3 mm (fairyflies) to 30 cm across (great owlet moth)."
"Some insects have no eyes or many."
"Some insects have well-developed wings or none."
"Three pairs of legs."
"Legs modified for running, jumping, swimming, or even digging."
"Their closest relatives include Protura, Diplura, and Collembola."
"Insects can occupy almost every ecological niche except the deep ocean."
"Their body is divided into three regions (called tagmata): head, thorax, and abdomen."
"Mouthparts located outside of the head capsule."
"There is enormous variation in body structure amongst insect species."
"The great owlet moth can reach a size of 30 cm across."
"Some insects have no eyes."
"Some insects have well-developed wings or none."
"Legs modified for running, jumping, swimming, or even digging."
"The non-insect hexapods include Protura, Diplura, and Collembola."
