Abstract
Aphid growth on sucrose-rich plant sap of high osmotic pressure is underpinned by gut sucrase/transglucosidase activity and regulated proliferation of the aphid's complement of bacteria. This study will determine the enzymological basis of the sucrase/transglucosidase activity and the impacts of enzyme activity and the identity and density of bacteria on aphid osmoregulation and growth. One purpose of this integrated analysis of sugar utilisation, osmoregulation and insect-microbial interactions is to identify specific targets (e.g. gut enzymes) of value to aphid pest control.
