This work evaluates the tolerance of adult Limnoperna fortunei to aerial exposure at different temperatures. The aim was to contribute knowledge about factors, such as the mussel’s capacity for survival out of water over long periods, allowing the invasion of new environments after terrestrial transport. The analysis of the results revealed that the time of exposure to air influenced mortality at different temperatures throughout the experimental period (P < 0.001). The time to reach 100% mortality at temperatures of 10°C, 20°C, and 30°C were 11, 6, and 3 days, respectively. Mussel mortality outside the water is directly related to air temperature, so the higher the temperature is, the greater the mortality. The results suggest that in the case of the land transport of structures biofouled with L. fortunei, this species can remain alive for 2 to 10 days, depending on the ambient temperature. Thus, aerial exposure may be used as a strategy to control the dispersal of the golden mussel. However, the time required for effective elimination of all individuals depends on the air temperature. The aerial exposure can also be used to periodically clean industrial systems and to eliminate the dispersion of propagules by vectors (e.g., transport of equipments/watercrafts).

Limnoperna Fortunei (Dunker, 1857) (Bivalvia: Mytilidae) 在不同温度下对空气暴露的耐受性

这项工作评估了成虫对不同温度下空气暴露的耐受性。目的是提供有关因素的知识，例如贻贝长期离开水的能力，允许陆地运输后入侵新环境。结果分析表明，在整个实验期间，暴露于空气的时间影响了不同温度下的死亡率（P < 0.001）。在 10°C、20°C 和 30°C 的温度下达到 100% 死亡率的时间分别为 11、6 和 3 天。水外贻贝的死亡率与气温直接相关，因此温度越高，死亡率越高。结果表明，在陆路运输被 L. Fortunei 生物污染的结构中，该物种可以存活 2 到 10 天，具体取决于环境温度。因此，空中暴露可用作控制金贻贝扩散的策略。但是，有效消灭所有个体所需的时间取决于气温。空中暴露也可用于定期清洁工业系统并消除载体（例如，设备/船只的运输）传播的繁殖体。
