Predicting the Potential Invasive Range of Klambothrips myopori (Thysanopetra: Phlaeothripidae)

Abstract Temperature-driven development of myoporum thrips, Klambothrips myopori (Thysanopetra: Phlaeothripidae), was examined at seven constant temperatures (15, 17, 20, 25, 30, 34, and 35.5°C) on Myoporum laetum Forst (Lamiales: Scrophulariaceae). Thrips successfully completed development to adult stage between 15 and 35.5°C. One linear and three nonlinear models were fitted to describe developmental rates of K. myopori as a function of temperature, and for estimating thermal constants and bioclimatic thresholds (Tmin, Topt, and Tmax). The Briere-1 model performed best in describing the developmental rate of cumulative life stages. Two ecological niche models, CLIMEX and Maxent, were used to predict the geographic distribution of K. myopori in its native range and globally. Overall predictions of environmental suitability differed greatly across models. The CLIMEX model accurately predicted known invasive and native localities, while the Maxent model failed to predict the native localities and parts of the invasive range. Based on the CLIMEX model, K. myopori has the potential to establish in many regions of the globe.
