| Research Abstract |
Aphids reproduce parthenogenetically and produce males and females in a single clonal line. In respect of each clone, aphids can be regarded as hermaphrodites. The present study investigated the pattern of sex allocation in several aphid species and obtained significant results from genetic and phylogenetic points of view. In particular, the study conducted in 2011examined in what pattern the sexual and hybrid strains of Acyrthosiphon pium pruduce males and sexual females. I found that in a hybrid strain, the females reared in a short day condition produced no viable males. This phenomenon agrees with Haldane's rule.
