EBONY, A SEMIDOMINANT LETHAL MUTANT IN THE MOSQUITO ANOPHELES ALBIMANUS

Abstract
Ebony (eb), a semidominant, autosomal mutant, was discovered in a stock of Anopheles albimanus Wiedemann that was treated with ethyl methane sulfonate. Ebony homozygotes are uniformly black during the four larval instars and die most commonly during the transition to the pupal stage. The heterozygotes (eb/eb+) are intermediate in color and fully viable. Propoxur resistance (prr) and the T(Y;2R)1 translocation were employed in crosses to assign eb to the left arm of chromosome 2.
