Abstract:

[Objectives]  To explore changes in the content of specific biochemical substances in the soybean pod borer after diapause, as well as the impact of different host plants and diapause-inducing temperatures on these substances. [Methods]  The anthrone-sulfuric acid and methanol-chloroform extraction methods were used to determine the lipid, water, total sugar, trehalose, and glycerol, content of soybean pod borers on different host plants at different diapause-inducting temperatures before, and during, diapause. The results were analyzed with SPSS17.0 data analysis software. [Results]  The lipid, total sugar, trehalose, and glycogen, content of soybean pod borers increased significantly when these entered diapause, but their water content decreased significantly. Soybean pod borers fed on cultivated soybeans had significantly higher water, total sugar, and glycerol, content, and significantly lower trehalose content, than those fed on wild soybeans. There were no significant differences in these biochemical substances between soybean pod borers kept under different diapause-inducting temperatures. [Conclusion]  The levels of different biochemical substances in the soybean pod borer were affected by host plant but not by temperature. Levels of the biochemical substances examined significantly differed before and during diapause.
