Insects represent almost all territories of the earth and account around 75% of total animal population. It is still ambiguous that being a cold blooded/poikilothermic organism, without acquired immune responses, how do they survive in all geographical regions of the world? Probably, it indicates its very strong innate immune responses i.e., cellular and humoral. Insect blood cells or hemocytes are the main component of cellular immune responses. They are biochemically very sensitive towards change and are the primary target of cellular defence system of insects and have proven their ability to mediate diverse immuno-defence processes against invading pathogens and other adverse conditions/stresses i.e., temperature, starvation, photoperiod, humidity etc. Therefore, in the present review, effort has been made to correlate various responses of hemocytes against the change, in order to propose hemocyte-based model in the form of catalogue to discern the health status and its future application in applied and biomedical sciences. Since hemocytes respond very instantly against change hence, it is expected that by using hemocyte catalogue as a pointer impact of several biotic and abiotic factors can be evaluated. Outcome of the present review will summarize the hemocytic response against adversaries/change in the form of catalogue for its potential use in applied and biomedical fields.
