The effect of temperature on midgut and brain protein profiles in Morimus funereus larvae (Coleoptera: Cerambycidae)

The 7-days shift of M. funereus larvae, from nature to a constant temperature of 23 degrees C led to changes in midgut and brain protein quality and quantity. The changes in midgut protein profiles are characterized by an intensified protein band Mr of 29 kD, the absence of protein Mr of 22 kD and less intense bands Mr of 8.5-2.5 kD. Electrophoretic patterns of brain proteins showed less intense Mr of 66-2.5 kD protein bands.
