摘要

Temperature preference of two invasive subterranean termites, Coptotermes gestroi (Wasmann) and Coptotermes formosanus Shiraki (Blattodea: Rhinotermitidae), and their hybrids were determined in a horizontal thermal gradient. The activity of workers of four mating combinations: female C. gestroi x male C. gestroi (C. gestroi), female C. formosanus x male C. formosanus (C. formosanus), female C. gestroi x male C. formosanus (Hybrid G), and female C. formosanus x male C. gestroi (Hybrid F), when placed on the temperature gradients were videotaped and analyzed to determine the mean temperature preference values (mTPV). The temperature ranges for active termites were 21.9-39.5 degrees C for C. gestroi, 11.1-39.5 degrees C for C. formosanus, 25.3-38.2 degrees C for Hybrid G, and 24.9-39.3 degrees C for Hybrid F. There was no significant difference in the mTPV of C. gestroi and both hybrid mating combinations. The mTPV of both Hybrid G and Hybrid F was significantly higher than the parental species C. formosanus. Our results indicate that hybrid populations of C. formosanus and C. gestroi might be more active in tropical than temperate regions, and if established in temperate regions, they will be more active in summer months when the mean temperature exceeds 25 degrees C.

Formosanus X雄性C. Gestroi（混合F）被染色并分析以确定平均温度偏好值（MTPV）。活性白蚁的温度范围为C.Gestroi，11.1-39.5摄氏度的C. FormoSanus，25.3-38.2℃，杂种G的25.3-38.2℃，24.9-39.3摄氏度。杂交F.没有显着C. Gestroi和混合交配组合的MTPV差异。杂种G和杂种F的MTPV显着高于父母种类C. Formosanus。我们的研究结果表明，C. Formosanus和C.Gestroi的杂交种群在热带地区可能比温带地区更活跃，如果在温带地区建立，它们将在夏季的平均温度超过25摄氏度时更活跃。
