Effect of trap color on species composition of alate aphids (Homoptera: Aphididae) caught over watermelon plants

The species composition and abundance of alate aphids caught in water traps containing green or yellow tiles were compared. Traps were operated in a watermelon field during the spring and autumn growing seasons of 1992. Aphis spiraecola Patch, a vector of watermelon mosaic virus 2 (WMV-2), accounted...

Summary:The species composition and abundance of alate aphids caught in water traps containing green or yellow tiles were compared. Traps were operated in a watermelon field during the spring and autumn growing seasons of 1992. Aphis spiraecola Patch, a vector of watermelon mosaic virus 2 (WMV-2), accounted for 79% of the aphids caught in the spring and 91% of those caught in the autumn in yellow traps. However, this species accounted for only 6% and 11% of aphids caught in green traps in the spring and autumn, respectively. Uroleucon pseudambrosiae (Olive), also a vector of WMV-2, was the most abundant aphid in green traps in the spring but was absent in the autumn. Aphis gossypii Glover (16% of aphids in green traps) and Aphis craccivora Koch (31%) were more common in the autumn than in the spring and may be important vectors of cucurbit potyviruses at that time. /// La compocisión y abundancia de especies de áfidos alados capturados en trampas de agua de color verde y amarillo en una plantación de sandía durante la temporada de primavera y otoño fueron comparadas. Aphis spiraecola Patch fue colectado en cantidades muy altas en trampas amarillas durante la primavera y otoño. Esta especie representó el 6% y 11% de los áfidos capturados en trampas verdes durante la primavera y el otoño, respectivamente. Uroleucon pseudambrosiae (Olive), otro vector del virus mosaico de la sandía tipo 2 (VMS-2), fue el áfido más abundante en trampas verdes durante la primavera; sin embargo, este vector no se atrapó en la temporada del otoño. Aphis gossypii Glover (16% de los áfidos capturados en trampas verdes) y Aphis craccivora Koch (31%) fueron más comunes en el otoño, indicando que pueden ser importantes vectores en epidemias causadas por potivirus en cucurvitaceas en esa estación.
