Fig. 9From: Defining the mechanisms of action and mosquito larva midgut response to a yeast-encapsulated orange oil larvicideYEOO and PM2 permeability. Confocal microscopy of dissected midguts from larvae fed either on inactivated yeast (a) or YEOO LC90 (b) for 4Â h in conjunction with FITC-labeled dextran (MW: 2000Â kDa). No FITC-dextran label (MW: 2000Â kDa) was observed in the caeca of either control or YEOO-treated larvae, suggestive of no change in PM2 permeabilityBack to article page
