简介：
Overview
This study presents a protocol for identifying differentially expressed genes in Aedes albopictus mosquitoes during diapause and non-diapause states. The approach involves rearing mosquitoes under different photoperiods, followed by RNA extraction and high-throughput sequencing to analyze gene expression variations.
