- As a target of insect growth regulators, the ecdysone receptor complex binds ecdysone agonists to regulate gene transcription, development, and growth. To understand the response of Lymantria dispar to methoxyfenozide, we studied receptor complex transcription profiles following larval exposure to methoxyfenozide, and observed important variations amongst post-embryonic stages. After the exposure of 2nd and 3rd instar larvae to LC5 and LC20 methoxyfenozide for 72 h, the transcription levels of ecdysone receptor complex genes were mainly upregulated in 2nd instar larvae, but downregulated in 3rd instar larvae. These results provide expression characteristics of the ecdysone receptor complex in L. dispar larvae after methoxyfenozide exposure.
