Midgut ultrastructural profiles of untreated, dsGFP-treated and dsDvSnf7-treated western corn rootworm (WCR) second instar larvae fed for 5 days.

<p>The letter L with orange glowing background indicates the region of gut lumen, white arrows indicate endosomes, magenta arrows indicate lysosomes, black arrows indicate autolysosomes and MLB is multi-lamellar bodies. C′ is for the magnified view of macroautophagic complex in the midgut of dsDvSnf7-treated individuals. Scale bars = 4 µm (a, b, c), 1 µm (a′, b′) and 500 nm (c′). D refers to macroautophagic complexes counted in enterocytes of untreated, dsGFP-treated and dsDvSnf7-treated larval midgut. Error bars represent mean ± S.D. of three individuals.
