Biology and ecology of eucalyptus psyllid pests in South Africa

The information in the data is used to gain new knowledge about the biology, host preference, and biological control agents of invasive eucalypt psyllid pests in South Africa. It includes data on morphometrics in the development of five immature stages of <em>Spondyliaspis</em> cf. <em>plicatuloides</em>, as well as the characterisation of leafy chemistry and morphology of eucalypts preferred and not preferred by<em> Glycaspis brimblecombei</em> and <em>Spondyliaspis</em> cf. <em>plicatuloides</em>. Furthermore, the parasitods of the studied psyllid pests' host specificity and host age preference were recorded.
