ABSTRACT
Three groups of Aedes aegypti maintained 8 generations in the laboratory at 20 degrees C, 27 +/- 1 degree C (normal control), and at 35 degrees C, respectively were analyzed for allozyme variability. Of the 8 larval loci examined Est alpha-1 and Lap-2 in generation 8 were still variable, while the other allozymes became uniform. The 35 degrees C population had mean level of heterozygosity of about 6% of individual per locus, less than those observed in the 20 degrees C and the control populations which were 14% and 13%, respectively. It is suggested that in the experimental populations, the rate of loss of alleles can be increased by high temperature which must not be higher than the optimum temperature of enzymes.
