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

ABSTRACT: Plants have evolved a variety of phytochemicals to defense insect feeding, whereas insects have also evolved diverse detoxification enzymes, which are adaptively induced as a prosurvival mechanism. Herein, Z-ligustilide in Ligusticum chuanxiong Hort. was found to exhibit a similar trend in the accumulation from December to May as the occurrence of Spodoptera litura (Fabricius) larvae. Importantly, S. litura larvae feeding enhanced Z-ligustilide level in the stem and leaf (p < 0.01). Moreover, Z-ligustilide ranging from 1 to 5 mg·g^-1 exhibited remarkable larvicidal activity, antifeedant activity, and growth inhibition against S. litura larvae. The LC₅₀ values of larvicidal activity for phthalides in L. chuanxiong were compared
