Keywords: Insect immunity, innate immunity, cellular component, humoral component


Insects are the largest existing group of animals under the Phylum Arthropoda. They are most diverse group of animals found in all the plausible habitats. Due to such diversity, different food habit they have to face a huge variety of parasites and pathogens, like bacteria, virus, fungus, protozoa, helminth, etc. Their immune system has played a vital role in their long-term survival in the evolutionary path. But like other invertebrates insects mainly rely on the innate immunity. Their innate components are highly specialized to combat against the parasites and pathogens. In this review article, we have described all the components and mechanisms of innate immune response of insect.
