Transcriptional responses of Eucalyptus clones to the gall wasp, Leptocybe invasa
… invasa (Hymenoptera:Eulophidae) is an Australian gall-inducing wasp that oviposits along immature midribs, petioles and stems. The larvae are endophytic herbivores that cause the development of coalescing galls (abnormal plant growths) and lead to a wide range of symptoms such as stunted growth, …

The biological control of the weed Acacia longifolia by the gall wasp Trichilogaster acaciaelongfoliae: a study of a plant-insect interaction
… successes. This thesis is an evaluation of the gall wasp Trichilogaster acaciaelongifoliae as a biocontrol agent for the weed Acacia longifolia in South Africa. The wasp has been successful, and, in accordance with Harris (1980a), my aims were twofold: to quantify that success and to provide …

Foraging on insect mutualists by the thatching ant Formica obscuripes: Interspecific and intraspecific mechanisms and implications
… thatching ant Formica obscuripes and the cynipid gall wasp Disholcaspis perniciosa. The success of all but specialized parasites, Eudecatoma spp that attack before the gall is available for ant attendance, decreased in the presence of ants. Gall wasp survivorship and fecundity schedules fell and …

Parallel and Nonparallel Patterns of Genetic Co-Differentiation: Evidence for Host Associated Differentiation Among Trophic Levels of the Oak Gall Wasp System
… treatae (Hymenoptera: Cynipidae) induces galls on three species of live oak (Quercus) across the southern USA. Both HAD and geography structure genomic variation among host associated populations of B. treatae. The generalist inquiline parasitoid, Synergus sp. (Hymenoptera: Cynipidae) …

Multitrophic Interactions in a Prairie Insect Community: Ecology, Behavior, and Conservation
… plant recognition by males and females of the gall wasp Antistrophus rufus Gillette whose larvae fed in S. laciniatum and S. terebinthinaceum. I used olfactometry bioassays in the field and lab and gas chromatography-mass spectrometry to identify the chemical cues they use to identify their …
