Flight-muscle polymorphism in the cricket Gryllus firmus: muscle characteristics and their influence on the evolution of flightlessness.

Physiological zoology - 1 Jan 2000

Zera A J, Sall J, Grudzinski K

Abstract excerpt

Flight muscles of the cricket Gryllus firmus are polymorphic, existing as pink or white phenotypes. White muscles are smaller in size, have reduced number and size of muscle fibers, and have reduced in vitro enzyme activities and respiration rates relative to pink muscles of newly molted, fully winged adults. G. firmus is also polymorphic for wing length. All newly molted long-winged adults exhibited the...
