Study on defense reactions of silkworm, Bombyx mori to Cordyceps militaris.
2010
The 5th instar larvae of the YUN7 silkworm were infected by Cordyceps militaris to investigate the defense reactions.The content of haemolymph protein and the activity of phenoloxidase in silkworm was determined,and the part of invasive fungus was revealed through microscopic examination.The result showed that the vale of silkworm is the main spot of body wall defenes reaction;The phenol oxidase defense factor started when M05 invade,and enzyme activity increased to 0.77U;Haemolymph protein content increased when silkworm started defense response.After fungus invasion consumed or destroyed partial protein of haemolymph,the protein content reduced.
