Climate elements and their relationship with the Guatemalan Moth Tecia solanivora (Povolný, 1973) (Lepidoptera: Gelechiidae) in potato (Solanum tuberosum L.) crop
Introduction. Climate variability and climate change scenarios influence the behavior of species and natural resources. The potato (Solanum tuberosum L., Solanaceae) crop produces a food of high nutritional value that is a staple in the family food basket. In Colombia, the production system is affected by pests, such as the Guatemalan potato moth caused by Tecia solanivora (Povolný), with few field studies describing its relationship with climate. Objective. To evaluate the effect of climatic elements on the adult male populations of T. solanivora in three potato crop cycles in a locality in Colombia. Materials and methods. In the municipality of Mosquera, Cundinamarca, Colombia, between November 2015 and October 2017, baited traps with sexual pheromone were located for the capture of adult Guatemalan potato moths in three potato cv Diacol capiro crop cycles, and the following were recorded: number of adults, precipitation (mm), relative humidity (%), minimum, mean, and maximum temperatures (°C), wind speed (km/h), solar brightness (h/day), agroclimatic indices of degree days (°Cd), reference evapotranspiration (mm/day), and water index (HI). Pearson and Dickey-Fuller tests, time series, and cross-correlation were performed. Results. The fluctuation of adults of T. solanivora was positively correlated with maximum temperature, degree days, and solar brightness, and a negatively correlated with precipitation (p<0.05). The maximum temperature (20 - 23 °C ±0.7 °C) presented the highest significance (p<0.05) of all the cross-correlations with Tecia solanivora, with a direct relationship when exceeding the autocorrelation coefficients, which increased the population and displacement of T. solanivora adults. The autocorrelation with precipitation (62 – 128 mm ±22 mm) showed population decrease (p<0.05). Conclusions. Climatic variables were critical limiting factors for the emergence and survival of T. solanivora.

La variabilidad climática y los escenarios de cambio climático influencian el comportamiento de las especies y los recursos naturales. El cultivo de la papa (Solanum tuberosum L., Solanaceae) produce un alimento de alto valor nutricional básico en la canasta familiar. En Colombia, el sistema productivo se ve afectado por plagas, como la polilla guatemalteca causada por Tecia solanivora (Povolný), con pocos estudios en campo que describan su relación con el clima. Objetivo. Evaluar el efecto de los elementos climáticos en las poblaciones de adultos machos de T. solanivora en tres ciclos de cultivo de papa en una localidad de Colombia. Materiales y métodos. En el municipio de Mosquera, Cundinamarca, Colombia, entre noviembre de 2015 a octubre de 2017, se localizaron trampas cebadas con feromona sexual para la captura de adultos de polilla guatemalteca en tres ciclos de cultivo de papa var Diacol capiro y se registraron: número de adultos, precipitación (mm), humedad relativa (%), temperaturas mínima, media y máxima (°C), velocidad del viento (km/h), brillo solar(h/día), índices agroclimáticos de grados día (°Cd), evapotranspiración de referencia (mm/día) e índice hídrico (IH). Se realizaron pruebas de Pearson y Dickey-Fuller, series de tiempo y correlación cruzada. Resultados. La fluctuación de adultos de T. solanivora presentó correlación positiva con la temperatura máxima, grados día y brillo solar, y correlación negativa con la precipitación (p<0,05). La temperatura máxima (20 - 23 °C ± 0,7 °C) presentó mayor significancia (p<0,05) de todas las correlaciones cruzadas con Tecia solanivora, con una relación directa al sobrepasar los coeficientes de autocorrelación, lo que incrementó la población y desplazamiento de los adultos de T. solanivora. La autocorrelación con la precipitación (62 – 128 mm ± 22 mm) presentó disminución de la población (p<0,05). Conclusiones. Las variables climáticas fueron limitantes críticas para la emergencia y supervivencia de T. solanivora.
