The aim of current study was to determine the effects of long-time exposure of Zn²⁺ on feeding behavior of English green aphid, Sitobion avenae (Fabricius). We had stimulated the natural Zn²⁺ stress by watering the different concentration of Zn²⁺ solutions to the wheat plants under controlled greenhouse conditions. The 1^st, 5^th, 10^th and 15^th generations of apterous S. avenae populations reared on those plants were used in the experiments. At the three leaves stage (about 14 days after germination), a single apterous adult S. avenae was transferred to the plants and monitored by electrical penetration graph (EPG). The results showed that the feeding behavior of S. avenae was significantly influenced by Zn²⁺ stress. In particular, at the 1^st and 5^th generations, total duration and number of np and C waveforms were lower than the control at the concentration of 200 mg/kg, while they were higher than the control at 800 mg/kg. Compared with the control, at 15^th generation, these parameters of S. avenae under the high dose were significantly increased. Moreover, for the penetrating feeding on phloem, no significant influence was found about the duration of E1 involved in salivation and number of E2 waveform involved in passive feeding. However, the durations of single E1, E1 followed by sustained E2 and numbers of E2 were decreased by high-dose Zn²⁺ stress. Meanwhile, the feeding behavior of S. avenae was influenced by Zn²⁺ and could produce the accumulated effects under the stress of high-dose Zn²⁺. However, the feeding behavior of S. avenae could be promoted by low dose of Zn²⁺. Based on that, the effective concentration was 400 mg/kg. The Zn²⁺ stress have changed the feeding behavior of S. avenae since the 5^th and 10^th generations. That was resulted from the total durations and numbers of np and C were extended and increased, while the number of E2 was decreased. These findings will provide a theoretical basis for controlling the damage from S. avenae under Zn²⁺ contamination conditions.
