A Study on the Adaptability Response between the Lac lnsect and lts Host Tree

Root secretion of the host tree and the quality of the lac produced are used as indexes based on which a study on the inter adaptability between the lac insect and its host tree is further conducted. According to the result,a decrease in the amount but an increase in the variety of amino acid in the secretion is observed in the host tree. Meanwhile,a significant difference in the composition of the lac is also observed on the lac insects of different host trees. The fact that lac is the secretion of lac insect shows that insects of the same species tend to develop different physiological bents.
