The yellow‐spined bamboo locust, Ceracris kiangsu Tsai (Orthoptera: Oedipodidae), is a notorious defoliator of bamboos in China. In commercial bamboo forests, spraying insecticides to control C. kiangsu is neither convenient nor economic, therefore environmentally acceptable and cost‐effective methods are needed. Ceracris kiangsu adults are known to aggregate and gnaw at human urine‐contaminated materials; NaCl is a strong phagostimulant and NH 4 HCO 3 is an attractant/arrestant. In the present paper, we found that foam plastic containers containing a blend of 0.03% bisultap, 3% NaCl, 3% NH 4 HCO 3 , and 0.1% Triton X‐100 (tetrad bait) had a powerful attracticidal effect and could kill a great number of especially female C. kiangsu adults, comparable to those containing a mixture of 0.03% bisultap and 5‐day‐incubated urine. In a field trial, the tetrad bait killed approximately 80% of females and about 9% of males in the treated plots after daily application for five consecutive days. The corrected average reduction rate was 48.2%. Moreover, the sex ratio was decreased from 1.18 before the trial to 0.25 after the experiment in the treated plots. These results indicated that there is the potential to develop a trap using NaCl as a phagostimulant and NH 4 HCO 3 as an attractant that can be used for C. kiangsu control.
