Web1 dag geleden · Not all parasitic wasps are successful biocontrol agents, Ghosh said. One reason is because the caterpillar’s immune system is composed of blood cells called hemocytes. These immune cells form hardened capsules around the parasitoid eggs, ultimately asphyxiating the parasitoid. But wasps can lay single eggs (solitary) or multiple … Web21 mei 2024 · Insects cannot produce antibodies because they lack the lymphocytes and immunoglobulin, so they rely on the rapid response of immune related hemocytes such as plasmatocytes and granulocytes. Thus, the immune system of insects is both non-specific and naïve when eliminating pathogens.
