Hello Shubham, 

The msc entomology course in IARI, eligibility criteria  is the person must have completed their bsc in agricagricul or horticulture or forestry or sericulture. So you are not eligible for it. If you really want to pursue entomology in IARI,  you can do your PhD in it. Msc zoology people are eligible to apply for it. Only bioinformatics course has the eligibility criteria for people who belong to any discipline can take it. If you are very particular about the college then you can choose this course. All the best!!
