| description | Chlorantraniliprole, serving as a substitute for traditional insecticide, has been widely utilized in controlling lepidopteran pests. <i>Loxostege sticticalis</i> (Lepidoptera: Crambidae) is a polyphagous insect and poses a significant threat as a migratory insect. This study investigated the life history traits of a field-collected population in response to chlorantraniliprole exposure based on an age-stage, two-sex life table. After treating the third-instar larvae of <i>L. sticticalis</i> with three different doses of chlorantraniliprole, namely LC<sub>10</sub>, LC<sub>25</sub>, and LC<sub>50</sub>, the survival, development, and fecundity of <i>L. sticticalis</i> were affected significantly in a dose-dependent manner. Chlorantraniliprole at doses of LC<sub>10</sub>, LC<sub>25</sub>, and LC<sub>50</sub> prolonged the average generation time (<i>T</i>) compared to the control group. The net reproductive rate (<i>R<sub>0</sub></i>) and intrinsic growth rate (<i>r</i>) were significantly higher in the LC<sub>10</sub> group but significantly lower in the LC<sub>25</sub> and LC<sub>50</sub> groups. Chlorantraniliprole used at a dose of LC<sub>10</sub> was shown to increase the finite growth rate (<i>λ</i>), while it decreased <i>λ</i> at doses of LC<sub>25</sub> and LC<sub>50</sub>. These results suggested that chlorantraniliprole induces hormetic effects by enhancing fecundity and reproductive potential at lower sublethal concentration (LC<sub>10</sub>), while reducing the reproductive output at higher doses (LC<sub>25</sub> and LC<sub>50</sub>). Our results provide useful information for developing management strategies for <i>L. sticticalis</i> involving the use of chlorantraniliprole. |
