Z-Ligustilide Exerted Hormetic Effect on Growth and Detoxification Enzymes of Spodoptera litura Larvae

Figure 1

S. litura larvae feeding contributes to the accumulation of Z-LIG in L. chuanxiong. (a) Representative images showing the occurrence of S. litura larvae in L. chuanxiong in the region of Pengzhou in Sichuan province, China. (b) The incidence rate of S. litura larvae in L. chuanxiong field from December to May. (c) The accumulation of Z-LIG in L. chuanxiong during different growth periods. The Z-LIG content in the rhizome and the stem and leaf was analyzed by GC-MS. (d) Influence of S. litura larvae feeding on the content of Z-LIG in the stem and leaf and the rhizome of the potted L. chuanxiong. After starvation for 4 h, Third instar larvae of S. litura were released to feed on the potted L. chuanxiong (2 larvae per plants). After 24 h, the plant materials were collected and the Z-LIG content in the rhizome and the stem and leaf was analyzed by GC-MS. Values are presented as means ± SD. () p<0.01. NS, nonsignificant.
