Entomology is the science that studies?

Appeared in: RRB Staff Nurse Delhi-2015

Explanation

Entomology is the specific branch of zoology dedicated to the scientific study of insects.
The term originates from the Greek word 'entomon', which means 'insect'.
This field covers all aspects of insect life, including their anatomy, physiology, behavior, and classification.
A crucial sub-specialty for healthcare is Medical Entomology, which studies insects that cause or transmit diseases to humans.

Option A: The study of human behavior is the domain of the behavioral sciences, not entomology.
Option C: This is too specific. While ants are insects, entomology is the broader science that studies all insects, not just ants.
Option D: This relates to earth science, not life science. The study of rocks is completely separate from the study of insects.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Definition of scientific fields as background academic context rather than a clinical decision trigger.
Understanding medical entomology is crucial for nurses to identify, prevent, and manage vector-borne diseases like Malaria, Dengue, and Chikungunya, which are major public health issues in India.
Nurses play a key role in patient education regarding preventive measures, such as using insecticide-treated mosquito nets, applying insect repellents, and eliminating stagnant water sources to control vector breeding.
A strong grasp of this topic helps in community health nursing, enabling nurses to conduct effective awareness campaigns and surveillance for vector-borne diseases.

How to Approach the Question

First, identify the key term in the question stem, which is 'Entomology'.
This is a factual recall question that tests your knowledge of scientific terminology.
If you know the definition, you can directly select the correct answer. If unsure, try to use word roots. 'Entomon' is Greek for insect, and '-logy' means 'the study of'.
Evaluate each option. 'Behaviour of human being' relates to psychology. 'Formation of rocks' relates to geology.
Compare 'Insects' and 'Behaviour of ants'. The study of ants is a sub-specialty. 'Insects' is the broader, more general definition for Entomology, making it the best answer.
