Abstract
This study investigates the thermal activity thresholds of the predatory mirid Nesidiocoris tenuis Reuter (Hemiptera: Miridae) and two spotted spider mite Tetranychus urticae Koch (Acari: Tetranychidae). Adult N. tenuis lost locomotory function and entered chill coma at significantly lower temperatures (4.0°C and 0.3°C, respectively) than adult T. urticae (7.0°C and 5.7°C, respectively). However, the mirids were more adversely affected by high temperatures, with T. urticae losing the ability to walk and entering heat coma at higher temperatures (47.3°C and 49.7°C, respectively) than N. tenuis (43.5°C and 46.6°C, respectively). Across a range of temperatures (2.5–20°C) adult N. tenuis had faster walking speeds than T. urticae. These data are discussed in relation to the climatic conditions under which N. tenuis would be an effective biocontrol agent.
