The effect of cold upon the development of pigment in a white-eyed mutant form of the blow-fly (Calliphora erythrocephala)



  1. 1.

    Pupae and mature larvae of the blow-fly (Calliphora erythrocephala) will continue to develop slowly at a temperature of 4°C.

  2. 2.

    White-eyed mutant females which emerge from pupae subjected to the low temperature have, at emergence, eyes of a deeper yellow colour than mutant females newly emerged from pupae which have developed at 21°C.

  3. 3.

    Some flies of the white-eyed mutant strain emerged after 6 months while still in the refrigerator at 4°C. These mutant females had red pigment granules deposited in the secondary pigment cells and probably also in the primary pigment cells. Red pigment granules are never formed in white-eyed mutant aemales which emerge from pupae kept at 21°C.
