>Morphogenesis and cuticular markers during the larval‐pupal transformation of the medfly Ceratitis capitata

Changes in morphology during early metamorphosis of the medfly, Ceratitis capitata (Wied.) (Tephritidae) were correlated with biochemical differentiation events. Protein profiles were studied both in the 3rd instar larval cuticle further transformed into puparium and the newly synthesized pupal cuti...
