RNA extraction from insect samples is a crucial step in molecular biology studies aimed at understanding gene expression, functional genomics, and various other applications. This study presents an optimized protocol for RNA extraction from insect tissues using TRIzol reagent. The protocol involves homogenizing insect samples in TRIzol, followed by phase separation with chloroform, RNA precipitation with isopropanol, and washing with ethanol. The final RNA pellet is dissolved in RNase-free water. This method ensures high yield and purity of RNA, suitable for downstream applications such as RT-PCR and RNA sequencing. The efficacy of this protocol was validated through spectrophotometric analysis and agarose gel electrophoresis, demonstrating its reliability and efficiency for extracting RNA from a wide variety of insect species
