Anoplophora chinensis (Forster) is a xylophagous invasive cerambycid whose larvae feed on the lower bole and exposed roots of many tree species in orchard, urban, and forested habitats. Larval survival and development of A. chinensis from Italy and China were evaluated at eight constant temperatures (5, 10, 15, 20, 25, 30, 35, and 40°C). Development was slow or did not occur at temperatures ≤10 and >35°C. The TMin for the first six instars and the pupa was <10°C, while TMin for the higher instars was closer to 12°C. The ultimate instar for both populations was insensitive to temperature. When the TMax thresholds could be estimated they were between 31 and 41°C. Temperature also influenced larval weight gain; larvae held at 25–30°C generally weighed the most from the fourth instar on. The number of degree days for 50% of the population to molt to the next instar increased with increasing instar for both populations up through the sixth instar. Anoplophora chinensis may use wood moisture content in conjunction with temperature as a cue as to when to pupate. These responses of A. chinensis to temperature can be used for developing phenological models to predict timing of stages for management or eradication efforts.
