Daegan joined Forest Research in 2006, following a post-doctoral role at the Natural History Museum, London, where he studied the evolutionary ecology and phylogenetics of termites and cockroaches. He also completed his PhD on dung beetle evolution and an MSc at the museum, in association with Imperial College, and has worked in southern Africa, Central and South America, and Madagascar.
Strategic research on the ecology and life history of new & emerging forest pests, in particular bark- and wood-boring beetles, and the risks they pose to British forests. Investigation into the susceptibility of UK woodlands to invasion by exotic insects, and research into the impacts of climate change on forest insect life cycles, distribution and pest status.
Susceptibility of UK forests to invasion by exotic bark beetles
Conducting a UK-wide inventory of bark beetles in key forest types. Researching the factors which influence the successful establishment of exotic bark beetle species, and consideration of risks posed by invasive species. Determination of the fungal associates of UK bark beetle communities, and the potential for transmission of tree-pathogenic fungi by beetle vectors (with Imperial College London).
The role of Agrilus biguttatus in Acute Oak Decline, and mechanisms of spread of the AOD bacteria
Project Leader, PhD Supervisor
A PhD research project on the ecology and development of the two-spotted oak borer, Agrilus biguttatus, which commonly occurs in association with the Acute Oak Decline disease. Novel life history data is being used to model this cryptic beetles’ distribution in the UK, and potential future impacts of climate change. We are also investigating how & when oak trees become susceptible to attack from the beetle. A new PhD will explore potential methods of spread between trees of the lesion-forming AOD bacteria.
nEUROSTRESSPEP, Novel biocontrol agents for insect pests from neuroendocrinology
An international consortium project to develop ‘greener’ biocontrol tools for pests of agriculture, horticulture and forestry, exploiting specific neuropeptide signalling hormones. Our detailed work on the life cycles of some key forest pests, and FR’s experience in forest trials, will be utilised to take this ground-breaking work from the laboratory to the field, and to address end-user needs in the forestry sector.
Pests and pathogens in a changing environment
Investigating the likely impact of climate change upon the life cycle, ecology, distribution and pest status of some key forest insects.
- The influence of a changing climate on development and voltinism in pine weevil, Hylobius abietis.
Exploring the relationship between the ecology and life cycle of Hylobius with temperature, and the development of phenology models to predict geographical variation in the number of generations per year under a changing climate.
- The influence of climate change on the interaction between an invasive forest pest and its natural enemy.
This PhD project combines laboratory, field and modelling research to understand the influence of climate change on geographical variations in life cycles and dynamic interaction between the European spruce bark beetle, Dendroctonus micans, and its natural enemy, Rhizophagus grandis.
- Fellow of the Royal Entomological Society
