Fig. 8From: Defining the mechanisms of action and mosquito larva midgut response to a yeast-encapsulated orange oil larvicideTUNEL assay of larval midgut after sublethal exposure to YEOO (LC50) for 24Â h. a Dissected midgut from larvae fed on inactivated yeast, b, c dissected midguts from either live (b) or moribund (c) larvae fed YEOO LC50. Increased DNA fragmentation is seen in the midgut of moribund larvae. Abbreviations: TUNEL, Terminal deoxynucleotidyl transferase dUTP nick end labelingBack to article page
