Manifestation of eight lethals in Coelopa frigida (F.)
Published online by Cambridge University Press: 14 April 2009
Extract
The time of action and morphological pattern of damage of eight recessive autosomal lethals in Coelopa frigida (F.) is described. Seven embryonic lethals are phase-specific in their time of action but lethal glassy may cause death at any time from the beginning of the third instar onwards.
A method for estimating the preadult viability of heterozygotes for lethals is described. Heterozygotes for lethal E/L3 show some impairment of viability, whereas, under conditions of larval competition heterozygotes for lethal E/L4 are superior in viability to their wild type sibs.
