昆虫寄主防御机制的研究很早就引起了科学家们的兴趣，对鳞翅目昆虫幼虫注射低剂量细菌时，发现其可作出有效的体液抗菌反应，开创了一系列先驱性的工作。到80年代初，从借古比天蚕（Hyalopboracecropia）滞育蛹的免疫血淋巴中分离到一种叫“cecropin”的抗菌肽。此后昆虫寄主? The research on insect host defense mechanism has long attracted the interest of scientists. When lepidopteran larvae were injected with low doses of bacteria, they found that they could make effective humoral antibacterial response and pioneered a series of pioneering work. By the early 1980s, an antimicrobial peptide called “cecropin” was isolated from the immune hemolymph of diapause pupae by Hyalopboracecropia. After insect host?
