Muestreo de poblaciones y actividad de vuelo de Aphis frangulae gossypii Glover (Homoptera, Aphididae) y otros pulgones sobre cítricos en Castellón

MELIA, A., 1995: Sampling populations and flight activity of Aphis frangulae gossypii Glover (Homoptera, Aphididae) and others aphids on citrics in Castellon. Bol. San. Veg. Plagas, 21(4): 601-610. The evolution of the population and the activity of flight of the four main species of aphids in citrics, Aphis frangulae gossypii Glover, Aphis spiraecola Patch, Toxoptera aurantii (Boyer de Fonscolombe) y Myzus persicae (Sulzer), have been studied on Clementine Clemenules and Oroval since 1985 to 1994, both included. The aphid that has had a denser population is the A. fr. gossypii and only one that has come over the threshold for intervention. On the fields these populations have been correlated with the captures of winged in yellow traps, settled on the ground, having established thresholds of usage of these traps.
