It seems that LdE74 mediates 20E signalling independent of the E75‐HR3‐FTZ‐F1 transcriptional cascade, which is required for larval–pupal metamorphosis and appendage growth in L. decemlineata.

Functional characterization of ultraspiracle in Leptinotarsa decemlineata using RNA interference assay

RNA interference of LdUSP in the final (fourth) instar larvae reduced the messenger RNA levels of four ecdysteroidogenesis genes and repressed the expression of five 20E signal genes in Leptinotarsa decemlineata, suggesting that USP is undoubtedly necessary for ecdystersoidogenesis, for mediation of 20E signalling and for initiation of metamorphosis in L. decem lineata.

Importance of Taiman in Larval-Pupal Transition in Leptinotarsa decemlineata

It is found that the LdTai mRNA levels were positively correlated with circulating JH and 20E titers in Leptinotarsa decemlineata; and ingestion of either JH or 20E stimulated the transcription of Ld Tai, indicating that Tai mediates both JHand 20E signaling.

Ecdysone receptor isoforms play distinct roles in larval–pupal–adult transition in Leptinotarsa decemlineata

Data suggest that EcR plays isoform‐specific roles in the regulation of ecdysteroidogenesis and the transduction of 20E signal in L. decemlineata.

It was showed that E74 plays a crucial role in the development, metamorphosis and reproduction of N. lugens, possibly via the interaction with βFtz-F1 at the genetic level, and provides a basis for the development of new target-based pesticides and new methods for the effective control of N .

RNA interference targeting ecdysone receptor blocks the larval–pupal transition in Henosepilachna vigintioctopunctata

There is a possibility of practical application of dsEcR as an environmentally friendly RNA pesticide to control H. vigintioctopunctata larvae, and high RNAi efficacy was obtained and identical RNAi phenotypes were observed in treated larvae.

In vitro midgut culture and in vivo bioassay revealed that 20E and an ecdysteroid agonist halofenozide (Hal) enhanced LdE75 expression in the day 1 final larval instars, and ingesting dsE75‐1 and ds E75‐2 from a common fragment of the three isoforms successfully knocked down these Ld E75s, and caused developmental arrest.
