| Abstract: | Experiments were conducted to study sexual isolation among two natural
populations of Drosophila ananassae maintained
at 18 °C and 24 °C for 12 generations in the
laboratory to see the effect of this environmental variable on behavioural
isolation. Multiple choice technique was used and matings were observed
directly in Elens Wattiaux mating chamber. Results showed sexual isolation
among strains that were maintained at different temperatures, indicating that
temperature may have affected the mating behaviour of the flies which resulted
in the induction of ethological isolation among the strains. |
