Extract

The inheritance of black pupa in Lucilia cuprina (Wied.) was investigated by means of a series of back-crosses through five generations. Since an approximate 1:1 ratio of reddish brown to black pupae was observed throughout, it is concluded that the character black pupa is due to a single recessive gene (bp).

A test for the existence of a linkage group containing genes for black pupa and dieldrin-susceptibility was then made. The exposure of females from reddish brown and black pupae derived from back-crosses to discriminating levels of dieldrin, and the pattern of mortality observed with scalar concentrations of dieldrin, indicated that genes for black pupa (bp) and dieldrin-susceptibility (rdi) are on different chromosomes.
