        | No. | Sample | DNJ (mg/g) |  
        | 1 | matured larvae I | 0.30 ± 0.030 d |  
        | 2 | matured larvae II | 0.13 ± 0.010 b |  
        | 3 | urine of matured larvae | 0.0044 ± 0.0031 a |  
        | 4 | feces of matured larvae | 0.96 ± 0.060 e |  
        | 5 | pupae | 0.23 ± 0.020 c |  
        | 6 | moths before excreting urine | 0.24 ± 0.040 c |  
        | 7 | urine of moths | 0.029 ± 0.013 a |  
        | 8 | moths after excreting urine | ND a |  | 
  
    | Note: Matured larvae I means that the matured larvae have not excreted all the
      urine and excrement; Matured larvae II means that the matured larvae have
      excreted all the urine and excrement and have begun silking; ND: not detected.
      Values are expressed as the means ± SD (n=3). Means without the same letters
    were considered significant, tested by one-way ANOVA and Fisher’s LSD, p ≤ 0.05. |
