The meteorological polarimetric radar RMA1 located in the city of Córdoba was used for a nonconventional phenomenon detection. Massive migrations of both Ascia monuste during early summer of 2015 and Schistocerca cancellata during late winter of 2017 were characterized by means of polarimetric variables (correlation factor ${\rho }_{\mathit{hv}}$ and reflectivity factor $Z_H$). The butterfly swarms show a pulsating behavior as a consequence of biological needs. The highest altitude detected was 2400 m msl. The correlation factor confirms the biological characteristic of the echo. The locust swarm migration shows a different pattern in several ways. First, it has a more uniform aspect regarding its displacement. Second, the locusts were observed to attain altitudes of 1700 m msl. Third, the correlation coefficient for the locust case showed regions with high values, which are different from the low value areas. It is concluded that radar observations of insect species may result in useful biological criteria for the government to asses areas that need to be protected for agricultural production.

位于科尔多瓦市的气象极化雷达RMA1用于非常规现象检测。通过极化变量（相关因子）表征了2015年初夏的黑加西亚（Ascia monuste）和2017年冬后期的加拿大血吸虫Schistocerca cancellata的大规模迁移。${\rho }_{\mathit{v}}$ 和反射系数 ${ž}_H$）。蝴蝶群由于生物学需要而表现出搏动行为。检测到的最高海拔是2400 m msl。相关因子确定了回波的生物学特性。蝗虫群的迁移在几种方面显示出不同的模式。首先，它在位移方面有一个更为统一的方面。其次，观察到蝗虫的海拔高度为1700 m msl。第三，蝗虫情况的相关系数显示高值区域，与低值区域不同。结论是，雷达对昆虫种类的观察可能会为政府评估有用的生物标准提供依据，以评估需要为农业生产保护的地区。
