Introduction
If you are preparing for agricultural competitive exams like the Bihar Plant Protection, IBPS AFO, UPCATET, CUET, ADA, or any other state agriculture examination, mastering the History of Entomology in India is non-negotiable. This topic is filled with factual points, historical dates, and pivotal discoveries that frequently appear in exams.
While the scientific study of insects began much earlier globally, recorded observations and scientific research on Indian insects predominantly started in the 18th century. In this comprehensive guide, we will break down the chronological milestones, legendary scientists, important legislative acts, and the fascinating history of biological control in India. Let’s dive in!
Early Observations and Key Scientists (18th to 20th Century)
The early history of entomology in India is marked by the arrival of international scientists who laid the foundation for insect study in the subcontinent.
- 1758 - J.C. Fabricius: A Danish entomologist who became the first to conduct an extensive study on Indian insects.
- 1767 to 1779 - J.G. Koenig: He was the first to study Indian insect types in detail. He collected a massive number of insects from the Coromandel Coast in South India.
- Exam Tip: The Red Cotton Bug (Dysdercus koenigii) is named after him, as he was the one who discovered and introduced it.
- 1782 - Dr. Kerr: He published the first scientific account of the Lac insect. He originally named it Coccus lacca, which was later renamed Laccifer lacca and eventually Kerria lacca in his honor.
- 1791 - Dr. J. Anderson: Published a crucial monograph specifically on the Cochineal scale insect.
- 1901 - L. de Niceville: Appointed as the very first entomologist to the Government of India (British India).
- 1903 - H. Maxwell-Lefroy: Appointed as the second official entomologist to the Government of India.
Timeline of Major Institutions and Organizations
Understanding the establishment of research bodies is crucial for your exams. Here is a simplified timeline:
| Year | Event/Establishment | Key Details |
|---|---|---|
| 1905 | IARI Established | Set up in Pusa, Bihar. H. Maxwell-Lefroy was designated as the first Imperial Entomologist. |
| 1925 | Indian Lac Research Institute | Established in Ranchi (now in Jharkhand). It is presently known as the Indian Institute of Natural Resins and Gums. |
| 1937 | Dedicated Entomology Division | Started at IARI, New Delhi (relocated from Bihar after an earthquake). |
| 1937 | First Storage Pest Laboratory | Started in Hapur, Uttar Pradesh (under IARI control). |
| 1938 | Entomological Society of India (ESI) | Founded in New Delhi. Mian Afzal Husain was the 1st President, while Dr. Hem Singh Pruthi and Ramakrishna Ayyar were Vice Presidents. |
| 1939 | Locust Warning Organisation (LWO) | Established in Jodhpur to exclusively monitor and control locust threats. |
| 1946 | DPPQ&S Established | Directorate of Plant Protection, Quarantine & Storage established with its headquarters in Faridabad, Haryana. |
Legendary Entomologists and Their Contributions
Several pioneering figures shaped modern Indian entomology. Here are the most important ones to remember:
1. Dr. Hem Singh Pruthi
- 1934: Became the first Indian to hold the prestigious post of Imperial Entomologist at IARI.
- 1946: Appointed by the Government of India as the first Plant Protection Adviser.
2. H. Maxwell-Lefroy
- First Imperial Entomologist.
- Published landmark books: The Indian Insect Pests (1906) and Indian Insect Life (1909).
3. Dr. S. Pradhan
Often celebrated as the Father of Modern Applied Entomology in India. His major contributions include:
- Publishing the book Insect Pests of Crops in 1969.
- Formulating the concept of the "Pesticide Umbrella".
- Discovering the "Pusa Bin" (a storage structure).
- Reporting the antifeedant properties of Neem, proving that insects actively avoid feeding on it, a major breakthrough for natural pest control.
4. M.R.G.K. Nair
- Authored the comprehensive book Insects and Mites of Crops in India in 1975.
Important Legislative Acts in Indian Entomology
To prevent the entry and spread of exotic pests, the Indian parliament enacted several critical laws.
💡 Exam Tip: Expect at least one direct question from this section!
- 1912 - The Plant Quarantine Act: Enforced to monitor agricultural imports.
- 1914 - Destructive Insects and Pests Act (DIPA): Introduced to regulate and restrict the introduction of harmful insects into India from foreign countries.
- 1968 - Central Insecticide Act: Enacted by the Parliament in 1968, though it officially came into force on January 1, 1971.
History of Biological Control in India
Biological control is the use of natural enemies (predators, parasitoids, or pathogens) to manage pest populations. India has a rich history of importing and exporting natural enemies.
Text Flowchart: Evolution of Biological Control in India
- 1762: 🐦 Indian Myna Bird introduced from India to Mauritius to control the Red Locust.
- 1898: 🐞 Ladybird Beetle introduced from Australia to South India to control Citrus Mealybug and Coffee Green Scale.
- 1929: 🪲 Vedalia Beetle (Rodolia cardinalis) introduced in Tamil Nadu to control the Cottony Cushion Scale.
- 1937: 🐝 Aphelinus mali introduced from North America to Tamil Nadu to control the Woolly Apple Aphid.
- 1960: 🦟 Tachinid Parasitoid (Spogossia bezziana) introduced from Sri Lanka to control the Coconut Black-headed Caterpillar.
- 1977: 🔬 AICRP on Biological Control of Crop Pests and Weeds was initiated.
- 1981: 🏢 India's first private insectary and biocontrol research laboratory was established in Bengaluru.
- 1993: 🏛️ The Project Directorate on Biological Control became an independent institute in Bengaluru.
- 2009: 🌟 Upgraded to the National Bureau of Agriculturally Important Insects (NBAII).
Key Concepts Explained
- Entomology: The scientific study of insects.
- Plant Quarantine: Regulatory measures taken to prevent the introduction and spread of pests across borders.
- Biological Control: Managing agricultural pests by using their natural enemies (like predatory beetles or parasitic wasps) rather than chemical pesticides.
- Antifeedant Property: A characteristic found in certain substances (like Neem) that stops pests from eating the treated crop.
- Parasitoid: An organism that lives on or inside a host insect and eventually kills it, heavily utilized in biological control (e.g., Tachinid Parasitoid).
Summary (Quick Revision Points)
- 18th Century: Scientific observation of insects in India began.

Conclusion
The history of entomology in India is deeply intertwined with agricultural development and food security. From the earliest taxonomic collections by J.G. Koenig in the 18th century to the establishment of modern institutions like NBAII, Indian entomology has evolved to tackle massive pest challenges using legislation and advanced biological controls. Mastering these dates, acts, and scientific figures will give you a significant edge in your agricultural competitive exams.
