Abstract
A new mutant, called bleached-eye, was discovered in Aedes taeniorhynchus (Wiedemann). Both the compound eyes and the larval ocelli of the mutant have only a slight pinkish color. In addition, the larval and pupal fat bodies are lightly pigmented. A series of crossing experiments revealed that bleached-eye (bl) is inherited as a simple autosomal, recessive to wild (+) type. Reduced hatchability and increased larval mortality occurred in bl mosquitoes when the maternal parent possessed the bl/bl genotype. The bl embryos from heterozygous (bl/+) females and normal embryos from bl females were not affected. These maternal effects associated with the bl mutant are conditional on the presence of an embryo with a bl/bl genotype. Nearly all eggs laid by bl females are rescued by bl+-bearing sperm. The sex of the offspring does not influence survival.
