In this study, conservation biological control principles were explored to determine whether the efficacy of Aphidius ervi Haliday (Hymenoptera: Braconidae), a parasitoid of the pea aphid Acyrthosiphon pisum Harris (Homoptera: ...

In this thesis, experiments were conducted in the laboratory and the field to determine whether the provision of floral resources to hoverflies could enhance the biological control of aphids. The overall aim was to clarify ...

The lens of the eye is a vital tissue in the visual system, responsible for the collection and focusing of light on to the retina. Comprised of epithelial cells at differing stages of differentiation, the transparency of ...

This document is the initial report on a systematic approach to the application of MLP to the aphid prediction problem. The aims of this initial work are three-fold; to investigate the effectiveness of a particular ...

This report presents two further experiments over the aphid data set. The first is an evaluation of the adaptive abilities of backpropagation of errors trained MLP and a comparison of these capabilities with the Simple ...

This report presents two further experiments over the Aphid data set. The first is a more detailed investigation of the sensitivity of Simple Evolving Connectionist System (SECoS) networks to the exclusion of various ...
