Host specificity and host stage preference of Psyllaephagus species (Hymenoptera: Encyrtidae) towards invasive eucalypt psyllids (Hemiptera: Aphalaridae)

The data set captures experimental results from laboratory tests assessing the host specificity and host stage preference of Psyllaephagus species (P. blastopsyllae, P. pilosus, and P. bliteus) toward invasive eucalypt psyllids (Blastopsylla occidentalis, Ctenarytaina eucalypti, Glycaspis brimblecombei, and Spondyliaspis cf. plicatuloides). The dataset includes data from choice and no-choice tests, host stage preference trials across five nymphal stages, and parasitoid development assessments. Key variables include parasitoid emergence rates, host stage preferences, and developmental outcomes on target and non-target psyllid species.
