Insects dominate the animal kingdom, both in terms of numbers and variety. One reason for their success is their remarkably swift and effective system of defense against infections, which differs dramatically from the immune systems of higher-order animals, including humans. Key to the insect immune system is an array of small antimicrobial peptide molecules. Most act, in essence, by latching on to the outer or inner membranes of bacteria and punching holes in the membranes, thereby killing the bacteria.
