Insects have evolved various defense strategies involving both humoral and cellular immune responses to combat invading foreign pathogens. Encapsulation is a conserved cellular immune process targeted against any foreign intruder which is too large to be phagocytosed.
The polyhydroxylated derivatives of 7-dehydro, 6-ketocholesterol (Ecdysone, Ecdysteroids, Ecd) were accidentally discovered in the search for an insect moulting hormone in 1965. The first Ecd compound, named ecdysone (“ecdysis” = shedding off the cuticle), was isolated from
