OBJECTIVE OF THE DEPARTMENT

To boost up the sustainable tea farming in North East India by developing integrated pest management (IPM) programme, which may help to overcome the overuse of pesticides and consequent residue problems.

BRIEF HISTORY OF THE DEPARTMENT

The Entomology unit started functioning with the appointment of Mr C. B. Antram as the Entomologist in 1906 at Kannykoori in Cachar. The unit was shifted to Tocklai in 1911. The same year Mr. Antram resigned and Mr. E. A. Andrews took over the charge of the Department.
Earlier Dr G. Watt (1895), Dr H.H. Mann (1900-1907), Mr. C. M. Hutchinson (1903-1908) and Dr. G.D. Hope (1909) did some pioneering work at the initiative of the ITA.From 1948 to 1960 the Entomology section was under the Plant Pathology Department along with the Mycology Department. In 1958, a new ‘Pesticide Testing Unit’ was created. In 1961 all the three sections were brought under the “Plant Protection Department”. The Entomology Department started functioning independently from 1967. The Pesticide unit was merged with Entomology in 1971. In 1978, both the Entomology and Mycology Sections were re amalgamated as Plant Protection Division. In 2011-12 the concept of division was abolished and independent full-fledged identity was given to Entomology Department.

ACTIVITIES OF THE DEPARTMENT

1. The Department of Entomology is seriously involved in the research activities based on the development of integrated pest management strategies to ensure sustainable and safe living and working environments in the tea eco system.

2. The Entomology Department is engaged in the studies of bio-ecology of pest complex of tea, shade trees and ancillary crops and their management. Recommendation of pesticides for commercial use is made after thorough screening. The department also carries out testing of spraying equipments and nozzles, etc. Preparation of tea samples for residue studies and tainting are done by the Dept.

3. Analytical services for the diagnosis of pest and nematode infestations are also rendered through this laboratory. Estimation of root knot nematodes for nursery soils is another service rendered to the plantations.

4. Providing training and work shop to the planters for sustainable and integrated pest management for tea and advisory services to the members.

R & D Activities of Biochemistry Department

I ) Evaluation of plant extracts having pesticidal property.

II ) Use of entomopathogens and natural enemies.

III) Use of light and sticky traps.

IV) Studies on semiochemicals.

V ) Insect resistance management.

VI) Bio ecological studies of different tea pests.The faunistic surveys were led by the Tocklai entomologists from the year 1901to establish the Imperial Entomological Museum in Tocklai Experimental station, which is one of the oldest and largest collections of its kind in India. Now this collection houses more than twenty thousand specimens of which majority are authentically identified.

A major achievement of the department has been balance achieved in pursuing both the basic and applied aspects of tea entomology. The Department is particularly proud of its success in IPM package for tea pests of North East India.
