He initiated pioneer studies on soil arthropods of this region as parts of Ph.D. researches and through a research project financed by ICAR. It is to his credit that the postgraduate teaching in Entomology and Agricultural Zoology started in 1968. Sufficient addition was made in applied as well as fundamental researches after Dr. Lallan Rai joined this Department as Professor in 1974. Separate research laboratories of toxicology, physiology, ecology, economic entomology and acarology were established. The faculty strength of the department was increased with the appointment of Dr. H.K. Singh as lecturer on 01.03.1976, later on Dr. H.K.Singh was appointed as Reader-cum-Entomologist (Pulses) on 01.01.1986 in the department, further two teachers namely Dr. Paras Nath and Dr. N.N.
