The Effect of Different Nitrogen Doses in Two Sugar Beet Varieties on Population Development of Aphids (Homoptera:Aphidoieda)
Öz
Population developments of aphid species on two sugar beet varieties, Eureka (monogerm) and S-814 (triploid),
fertilized with four different nitrogen doses (0, 15, 25, 35 kg/da) were surveyed in Altinekin – Konya province of
Turkey. The experiment was completely randomized design with three replications. The survey revealed that the
sugar beet varieties were harbored only two aphid species under given experimental conditions. The most common
species was Aphis fabae Scop. with a relative frequency of 91%, while Myzus persicae Sulz. was relatively less
abundant (9%) in the sampled areas.
In almost all plots, the first aphid occurrence was observed at the beginning of June, which coincides with 7-8
leaf stages of sugar beet varieties. The aphid populations peaked around mid July when the leaf number was maximum
(15-20 leaf stage) for sugar beet. Then the populations gradually declined until the beginning of August probably
due to increase in air temperature, and completely collapsed by mid August.
The abundance of A. fabae on variety S-814 was more than that of Eureka (P<0,01). Both A. fabae and total
aphid population were parallely increased with increasing nitrogen doses (P<0,05). The highest number of aphid
(229,67 + 16,65 aphid/plant) was found on variety S – 814 fertilized at 35 kg/da rate, whereas variety Eureka on
control plots harbored the lowest number of aphids (55 + 10,58 aphid/plant). For M. persicae, an effective virus
vector, while the differences between varieties were not significant, only the difference between unfertilized and
highest nitrogen dose were statistically important (P<0,05). Overall, due to aphid tendency toward nitrogen rich
plots, fertilization over 15-20 kg nitrogen/da was not suggested to control aphid population growth in sugar beet
fields.
