Population control of the yellow-spined bamboo locust, Ceracris kiangsu, using urine-borne chemical baits in bamboo forest

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