Liam Harvey

Welcome to my e-portfolio. I completed a BSc in Conservation Biology and Ecology at the Centre for Ecology and Conservation, 2010 (University of Exeter, Falmouth campus). I then went on to complete a MSc in Food Security and Sustainable Agriculture at the University of Exeter, 2012, investigating the sub-lethal effects of imidacloprid on the performance of Bombus species (For more qualification information see below). My main interests lie in ecology and the development of strategies that lead to a reduction in the use of synthetic agrochemicals, particularly biological control. Currently, as part of a PhD, I am investigating the mid-season ‘crash’ of aphid populations in field Brassica crops. My three year studenship is funded by AHDB Horticulture.

The role of natural enemies in regulating aphid populations on vegetable Brassica crops

Research aim:

The proposed work will test the hypothesis that fungal epizootics are one of the principle factors causing the mid-season crash in populations of aphids on horticultural brassicas.


i. Monitor populations of healthy and fungus-infected cabbage aphids on sequentially planted brassicas and study the link between the mid-summer population crash and epizootics of insect pathogenic fungi.

ii. Identify insect pathogenic fungi associated with the cabbage aphid Brevicoryne brassicae on field brassicas.

iii. Use laboratory bioassays to measure the susceptibility of the cabbage aphid to fungi collected from the field and compare to commercial mycopesticides.

iv. Model the effect of temperature and moisture on the pathogenicity of fungi to the cabbage aphid to forecast the outbreak of fungal epizootics.
