TEM of larval midgut after 30 min of YEOO LC₉₀ exposure (30 min after ingestion of YEOO). a No detectable microvilli and increased blebbing in the nucleus (N) and incipient fragmentation of the nuclear membrane (dashed arrow), with the PM2 still visible (arrows). b Greater magnification of apical cell surface with loss of microvilli (#) and blebbing of cell membrane with the PM2 (pm) still intact. c Detailed view of the apical epithelium (#) with significant destruction of the microvilli network. No YEOO are visible within the peritrophic space (*) surrounded by the PM2 (pm. d Slightly increased vacuolization is seen near the basal lamina (b) of midgut epithelial cells with still uniform mitochondria (m)
