- Abstract
Agricultural ecosystems are characterized by high spatial variability in abiotic characteristics that affect insect pest establishment and spread. The role of physiological responses to abiotic factors has been recognized as fundamental to insect range formation. Here we focus on the effects of various abiotic factors with potential to affect the probability of insects achieving pest status and propose ways to improve insect pest risk analyses using empirical as well as theoretical approaches. We discuss the data types used for pest risk analysis and present a process flowchart for preliminary pest risk assessment at both local and regional scales. This approach allows a quick assignment of preliminary risk levels taking into account known thermal thresholds for survival, effect of climatic factors on insect development, population dynamics as well as impact of local and regional landscape characteristics and soil properties on species abundance and dispersal. Using the process flowchart we conduct preliminary risk assessments for the carrot weevil, Listronotus oregonensis LeConte (Coleoptera: Curculionidae), and the brown marmorated stink bug, Halyomorpha halys Stal (Heteroptera: Pentatomidae), in Nova Scotia to demonstrate the utility of the framework.
