Entomology, derived from the Greek ‘entomon’ (insect) and ‘logos’ (study), is the science that is responsible for the study of insects in all its facets. The presence of insects is omnipresent in our environment, from wildlife to our homes, being crucial for the ecological balance and the survival of many ecosystems.

entomology investigate insects and entomologists analyze the morphology of insects and their development from the egg stage to adulthood.

What is an entomologist?

An entomologist is a scientist specializing in the study of insects, dedicated to investigating and understanding their lives. His work consists of:

  • Gather.
  • Identify.
  • Sort out.
  • Analyze.

The entomologist uses a variety of techniques and tools to carry out their work, such as:

  • Use of entomological nets.
  • Traps to collect samples.
  • Molecular and genetic techniques.

The field of work of an entomologist is wide and diverse. They intervene in the creation of strategies for the control of harmful insects.

The work of the entomologist can also be involved in scientific dissemination, educating the public about the importance of insects and their conservation.

be an entomologist requires passion for insects, scientific curiosity and perseverance in study and research. Their dedication and knowledge are fundamental to understanding and appreciating the importance of these beings.

What kind of animals does entomology study?

Entomology focuses on the study of insects, these are the largest group and diverse animal kingdom. Arthropods play a valuable role in terrestrial and marine ecosystems.

Among the groups of insects studied are:

  • beetles.
  • Butterflies and moths.
  • Bees and wasps.
  • Flies and mosquitoes.
  • Ants and termites.
  • Aphids and aphids.

In addition to these groups, entomologists can also investigate other insects, the information they obtain allows to know the role of insects in ecosystemsits relationship with other organisms and its influence on:

  • Agriculture.
  • Human health.
  • Biodiversity conservation.

Insects and Insect Infestation

In the field of entomology, special attention is paid to the study of insects in relation to pests. An insect pest refers to a uncontrolled proliferation of insects that causes economic, environmental or health damage. These insects can have a negative impact on agricultural crops, ornamental plants, human structures and public health.

Insect pest management can be based on both chemical and non-chemical approaches. Chemical methods include the use of insecticides to control and reduce populations of harmful insects. However, in recent years there has been interest in more sustainable non-chemical approaches.

He knowledge detailing of insects allows entomologists to:

  • Grasp better the reasons for the appearance of pests.
  • Toast solutions effective, respecting the environment.

Why are insects invertebrate animals of the arthropod kingdom?

Insects belong to the animal kingdom and are classified as invertebrates within the phylum arthropods. Arthropods are the largest and most diverse animal group, and comprise about 75% of all species known in the world.

The classification of insects as arthropods is based on common characteristics:

  • An external exoskeleton: It is the structural support of insects.
  • A rigid cover: Protection that covers your body.
  • a segmented body: Insects have three main body segments: head, thorax, and abdomen. The head contains the sensory organs and antennae, while the thorax houses the legs and wings in those insects that have them. The abdomen contains the internal organs and may present appendages such as cerci.

Insects are crucial in ecosystems, either as:

  • Plant pollinators.
  • Organic matter decomposers.
  • Natural pest controllers.

The diversity and abundance of insects have a significant impact on the biogeochemical cycles and in the food chain.

What is zoology?

Zoology is the branch of biology that is dedicated to the scientific study of animals. The word ‘Zoology’ derives from the Greek ‘zoon’ (animal) and ‘logos’ (study). Zoologists are dedicated to investigate and understand animal life in all its forms, from unicellular organisms to complex systems of ecological interaction.

Zoology is interested in the classification and taxonomy of animals. This classification is based on phylogeny, which studies the evolutionary relationships between species. It covers a wide range of specialties, such as:

  • Ichthyology (study of fish).
  • Herpetology (study of reptiles and amphibians).
  • Entomology (study of insects).

What is forensic entomology and what is it for?

Forensic entomology is a branch where knowledge of biology and insect behavior to solve crimes.

The main application of forensic entomology is in the estimate of elapsed time from death to the discovery of a corpse. Forensic entomologists analyze the stages of development and the composition of the species present in the carcass to determine the time elapsed since death.

What is agricultural entomology and what is its role?

Agricultural entomology is a branch of entomology that focuses on the study of insects in relation to the agriculture and crop production. Your goal is:

  • Understanding the interaction between insects and cultivated plants.
  • The development of strategies that manage insect populations sustainably.

The main function of agricultural entomology is protect crops and minimize damage caused by insect pests. Insects can have a significant impact on agricultural yields, either through feeding and damaging plants, or as vectors of plant diseases.

Agricultural entomology is also concerned with the study of pollinatorssuch as bees, and their importance in crop production.
