Gene expression of two antibacterial proteins was investigated using ligated larvae of the silkworm, Bombyx mori to explore the localization of the tissue responsible for receiving stimuli from injection of bacteria. For this Northern blot analysis was performed using two probes derived from cDNAs encoding cecropin B and attacin. Results showed that positive signals were detected only with RNA samples extracted from the site injected with bacteria in the ligated larvae and also in the decapitated larvae. The results were in contrast to gene expression of Sarcophaga lectin in ligated larvae of the flesh fly, Sarcophaga peregrina, in which only the anterior portion responded to body injury. These results suggest that there are at least two different mechanisms of gene expression of self-defense proteins in lepidopteran and dipteran insects.
