In holometabolous insects, the major developmental transitions – larval molting and pupation – are triggered by a pulse of 20‐hydroxyecdysone (20E) and coordinated by juvenile hormone. Methoxyfenozide (MF), an ecdysteroid agonist, represents a new class of insect growth regulators and is effective against lepidopteran pests. Fushi‐tarazu factor 1 (FTZ‐F1) is an ecdysone‐inducible transcription factor. To date, the effect of MF on 20E‐response genes remains unclear, and we speculate the involvement of FTZ‐F1 in MF's growth regulating effect.

剖析FTZ-F1在幼虫蜕皮和化up中的作用，以及甲氧基苯甲酰胺对棉铃虫的亚致死作用

在全脂类昆虫中，主要的发育过渡期-幼虫蜕皮和化are-是由20-羟基蜕皮激素（20E）的脉冲触发并由幼体激素协调的。蜕皮甾类激动剂甲氧芬尼（MF）代表了新型昆虫生长调节剂，对鳞翅目害虫有效。Fushi-tarazu因子1（FTZ-F1）是蜕皮激素诱导的转录因子。迄今为止，MF对20E反应基因的影响尚不清楚，我们推测FTZ-F1参与了MF的生长调节作用。
