Spatially explicit individual-based modelling of insect-plant interactions: effects of level of detail in Queensland fruit fly models

Abstract

A form of agent-based modelling known as individual-based modelling has been used widely to simulate hypothesised mechanisms underlying processes in the real world, especially in the field of behavioural ecology. To apply this approach to insect-plant interactions the Queensland fruit fly (Qfly), Bactrocera tryoni (Froggatt) (Diptera: Tephritidae), a major native insect pest of horticulture in Australia, will be examined. Due to restriction on use of some chemicals, currently there is no suitable management system for control of Qfly. However, better Qfly management can be potentially advanced by targeted behavioural, physiological and ecological research on this species. Many control options depend on behavioural fundamentals of Qfly such as foraging and movement patterns (e.g. trapping control technique), and the use of resources like protein and food sources (e.g. bait spray control technique).
