Fig. 3From: Ad libitum consumption of protein- or peptide-sucrose solutions stimulates egg formation by prolonging the vitellogenic phase of oogenesis in anautogenous mosquitoesAedes aegypti (a), Ae. albopictus (b), An. gambiae (c), An. stephensi (d) and C. quinquefasciatus (e) shunt BSA-sucrose solutions into both the crop and midgut. Each image shows an explanted digestive tract from a female provided ad libitum access to BSA-sucrose containing blue food dye for 24Â h. The crop, dorsal diverticula (DD), anterior midgut (AMG), posterior midgut (PMG) and Malpighian tubules (MT) are indicated; the hindgut is visually obstructed by the MT but contained only trace amounts of blue BSA-sucrose, similar to the foregutBack to article page
