✦ Synopsis

In experiments on sexual competition in Drosophila melanogaster, the course of mating succes with time is represented by a sigmoid curve. By logarithmic transformation such curves are changed into straight lines that can be compared by covariance analysis. This method allows discrimination of the behaviour of the two types in competition, and allows us to follow it in the course of time. From a sexual competition experiment between the wild type Canton S and the mutant white-ebony we conclude that sexual activity of males and females of both types is generally 'frequency dependent', with evidence of 'rare-female advantage' as well as 'rare-male advantage'.

Herein we demonstrate that Drosophila larvae possess a synthetic activity capable of converting phenylalanine to tyrosine. This system is readily extractable and displays many characteristics of phenylalanine hydroxylase systems described in other organisms, the most notable being that a tetrahydrop

Strong sexual isolation established between D. melanogaster long-term cage populations (originated from common parents and being under selection pressure since 1972) is maintained (with a tendency to increase) for twelve years after the origin of the populations. The sexual isolation is also maintai
