气候变化正在促使一系列昆虫物种的生命周期发生各种性质的变化，包括物候和化性的变化。在西班牙，有观察证据表明蛾Lobesia botrana Den。& Schiff。(Lep.:卷蛾科（Tortricidae）是一种重要的葡萄害虫，通常在地中海纬度地区三化性，倾向于提前春季出苗，显示出部分第四次额外飞行，这一事实可能归因于全球变暖。botrana物候在西班牙西南部的葡萄种植区，在过去的二十年（1984-2006年），利用飞行曲线与性信息素陷阱获得的数据库。计算了每个地区和年份的蛾的第二和第三次飞行高峰的日期，然后与时间（年）和当地温度进行了相关，得到的结果表明，在过去的20年中，当地变暖（由于全球变暖）的趋势值得注意，年和春季温度平均分别增加0.9和3.0摄氏度。因此，L. botrana的物候期大大提前了12天以上。此外，在2006年，物候的进步，促进了一个完整的第四次额外的飞行，这是从来没有报道过的事实，我们的知识在伊比利亚半岛蛾化性增加。botrana是从农业生态的角度来讨论的。
Climate change is promoting alterations of a very diverse nature in the life cycle of an array of insect species, including changes in phenology and voltinism. In Spain, there is observational evidence that the moth Lobesia botrana Den. & Schiff. (Lep.: Tortricidae), a key vine pest that is usually trivoltine in Mediterranean latitudes, tends to advance spring emergence, displaying a partial fourth additional flight, a fact that is potentially attributable to global warming.To verify this hypothesis, local temperatures were correlated with L. botrana phenology in six vine-growing areas of southwestern Spain during the last two decades (1984-2006) by exploiting the database of flight curves obtained with sexual pheromone traps. The dates of second and third flight peaks of the moth were calculated for each area and year and then correlated with both time (years) and local temperatures.The results obtained demonstrated a noteworthy trend towards local warming (as a result of global warming) in the last two decades, with mean increases in annual and spring temperatures of 0.9 and 3.0 degrees C, respectively. Therefore, L. botrana phenology has significantly advanced by more than 12 days. Moreover, the phenological advance contributed to increased moth voltinism in 2006 by promoting a complete fourth additional flight, a fact that has never been reported previously to our knowledge in the Iberian Peninsula.The potential impact of an earlier phenology and increased voltinism in L. botrana is discussed from an agro-ecological perspective.
