| description | Neoleucinodes elegantalis Guenee (Lepidoptera: Crambidae) represents the most damaging pest of the Solanaceae family. Current studies have demonstrated that the species has differentiated into four races according to variations in female genitalia, wing morphometrics and sequencing of the Cytochrome Oxydase 1 (CO1) mitochondrial gene. The number of males captured in Colombia and Ecuador were registered using traps baited with two sex pheromone: NeolegantolR and P228. These pheromones were synthesized using natural female pheromones collected in Solanum lycopersicum L. plantations in Venezuela. In Colombia, the number of male catches was significantly higher for NeolegantolR than for P228 and this number was significantly higher on S. lycopersicum followed by S. quitoense and S. betaceum. The haplotype net obtained with the CO1 gene produced two main clusters: one cluster was comprised by specimens from S. lycopersicum and S. quitoense plants (both with medium sized female genitalia) and the other cluster by specimens from S. betaceum (large sized genitalia). The NeolegantolR pheromone was also tested in Ecuador, however, insignificant number of males were attracted. Results suggest that pheromone composition or concentration, host biotypes and geographic location are relevant to monitor populations of N. elegantalis. Further studies of the species should concentrate on establishing the pheromone composition and concentration among the four biotypes. |

Neoleucinodes elegantalis Guenée (Lepidoptera: Crambidae) representa la plaga más perjudicial de la familia Solanaceae. Estudios actuales demostraron que la especie se diferenció en cuatro razas según la variación de los órganos genitales femeninos, la morfometría del ala y la secuencia del gen mitocondrial Citocromo Oxidasa1 (CO1). Se cuantificó el número de machos capturados en Colombia y Ecuador empleando trampas cebadas con dos feromonas sexuales: Neolegantol® y P228 sintetizadas a partir de la feromona natural de hembras recolectadas en plantaciones de Solanum lycopersicum L. en Venezuela. En Colombia, el número de machos capturados fue significativamente mayor con Neolegantol® que con P228, y este número fue significativamente mayor en S. lycopersicum, seguido por S. quitoense y S. betaceum. La red haplotípica obtenida con el gen CO1 produjo dos grupos principales: un clúster conformado por especímenes de S. lycopersicum y S. quitoense (ambas hospederas dieron origen a hembras con genital mediano) y otro de S. betaceum (con genitales femeninos de gran tamaño). El Neolegantol® también fue probado en Ecuador, pero las capturas fueron insignificantes. Los resultados sugieren que la composición o la concentración de la feromona, los biotipos hospederos y la ubicación geográfica son factores relevantes para monitorear las poblaciones de N. elegantalis. Otros estudios de la especie deben encaminarse a determinar la composición y concentración de la feromona entre los cuatro biotipos. 2017-09 2017-10-04T16:19:50Z 2017-10-04T16:19:50Z Journal Article https://hdl.handle.net/10568/88130 en Open Access Corporación Colombiana de Investigación Agropecuaria Díaz-Montilla, Ana Elizabeth; Suárez-Barón, Harold; Gallego Sánchez, Gerardo; Viera-Arroyo, William Fernando; Saldamando-Benjumea, Clara Inés. 2017.
