STUDIES ON THE INHERITANCE OF REPELLENT TOLERANCES IN AEDES-AEGYPTI

Two laboratory strains and 6 inbred strains of Aedes aegypti were test ed against deet, ethyl hexanediol, dimethyl phthalate, and Indalone(R) . Reciprocal crosses and backcrosses of 2 inbred strains were tested a gainst deet only. Results obtained were compatible with a quantitative genetic model in which the effects of the factors involved were multi plicative. Certain inbred strains differed significantly from cognate laboratory and/or inbred strains in tolerance to one or more test mate rials. Heritability in the broad sense (H-2) was estimated at 0.05 for deet, 0.22 for ethyl hexanediol, 0.48 for dimethyl phthalate, and 0.5 1 for Indalone. Partial dominance was observed in the inheritance of t olerance to deet.
